Как изменить размер в фотошопе cs6: Изменение размера изображений в Photoshop

Как изменить размер объекта в фотошопе при помощи инструмента перемещение

Зачастую, мы изучаем фотошоп с помощью уроков в интернете. Логично предположить, что существует определенный сленг, в котором разобраться новичку не так-то просто. Часто автор урока не считает нужным пояснять каждое действие, потому как считает их элементарным. А у новичка оно вызывает недоумение.

Сейчас я хочу дать вам ответ на вопрос: «как изменить размер объекта в фотошопе».

Начнем с пояснения, что представляет собой этот загадочный объект. Объектом может являться что угодно. Целое фото, его фрагмент или геометрическая фигура, даже текст! Все эти вещи можно подвести под одну общую черту. Они располагаются на отдельном слое. А именно – у вас есть возможность его изменить.

Давайте смоделируем ситуацию, в которой вам бы потребовалось изменить размеры объекта. Допустим, вам необходимо сделать коллаж. Для чего следует наложить на одно фото другое.

Возьмем для примера фото вот этого забавного пса.

Думаю, можно было бы сделать его чуть более серьезным, надев на него кепку с надписью police.

Кепка у меня в формате png. Как мы знаем, это формат позволяет сохранять изображения без заднего фона. Перетаскиваем кепку на исходное изображение с собакой.

Как видите, головной убор нашему другу явно маловат. Давайте его увеличим.

Убедитесь, что в окне слоев выделен нужный. С кепкой. Именно его мы будем изменять. Это важно!

Кликаем по инструменту «перемещение».

Вокруг нашего объекта появилась рамка, позволяющая изменить его размер. Мы можем поставить курсор на ее угол, и, придерживая правую клавишу мыши потянуть ее. Кепка увеличится.

Но стоит знать одну хитрость. Дабы кепка увеличивалась пропорционально, зажимайте клавишу shift.

Как видите, кепку мы увеличили, следственно, изучили, как изменять размер объекта в фотошопе.

Хочу оповестить вас еще об одной хитрости. Есть комбинация клавиш, позволяющая быстро вызывать рамку для последующего изменения объекта. Ctrl+t.

Тем, кто не до конца осознал произведенные действия. Этот метод сработает для любого объекта. Будь то геометрическая фигура, фото или текст. Объект может быть вырезанным или вставленным с другого фото или картинки. Такие мелочи не имеют значение. Не важна форма или происхождение объекта. Для них всех в Adobe Photoshop работает вышеописанный метод.

Как изменить размер изображения в фотошопе

Изменение размера изображения является одним из наиболее часто используемых навыков во всем Photoshop. Фактически, это настолько распространено, что даже людям, которые практически ничего не знают о Photoshop, все же удается использовать его для изменения размера своих изображений, что должно дать вам представление о том, насколько это легко сделать.

В этом уроке мы узнаем, как изменять размеры изображений, а также соблюдаем общее правило, чтобы ваши фотографии с измененным размером оставались четкими и четкими. Я буду использовать Photoshop CS5 здесь, но шаги те же, что и с любой последней версией программы.

Вот изображение, которое я открыл на своем экране:

Оригинальное фото.

Это фотография, сделанная во время поездки в Мексику. Конечно, оригинальная версия фотографии была намного больше, чем то, что мы видим здесь, но я изменил ее размер и уменьшил, чтобы он лучше подходил к странице. Как я это сделал? Это просто. Чтобы изменить размер изображения в Photoshop, мы используем команду « Размер изображения», к

которой мы можем перейти, зайдя в меню « Изображение» в строке меню в верхней части экрана и выбрав « Размер изображения» :

Перейдите в Изображение> Размер изображения.

Это вызовет диалоговое окно Размер изображения, как показано ниже:

Диалоговое окно «Размер изображения».

Этот снимок экрана диалогового окна «Размер изображения» был сделан сразу же после того, как я открыл исходную фотографию, а затем изменил ее размер до уменьшенной версии для отображения на странице. Если вы присмотритесь, вы заметите, что диалоговое окно разделено на два основных раздела — « Размеры в пикселях» и « Размер документа», каждый из которых показывает разные измерения. Так как этот урок посвящен тому, как изменить разм

Как изменить размер изображения в Фотошоп

Приветствую читателей блога ps-blog.ru! Один из самых распространенных навыков в Фотошоп, это изменение размеров изображения. Обладая этим навыком, вы легко сможете уменьшать и увеличивать любые изображения. Изменять размер изображения часто приходится для публикации в WEB, в журналы, для печати фотографий и много где ёще, поэтому если вы собираетесь работать в Фотошоп, то вы должны уметь это делать.

Скорее всего у вас возник вопрос: Как изменить изображение в Фотошоп? Всё просто. В этом уроке мы будем учиться открывать изображение в Фотошоп и изменять его размер. Как и в любом деле, здесь есть свои нюансы, с которыми вы рано или поздно столкнётесь и которые лучше нужно знать заранее, поэтому мы так же рассмотрим и эти нюансы. Предлагаю плавно перейти от теории к практике.

Шаг 1:

Откроем изображение, с которым будем работать. Для этого перемещаем курсор мыши вверх, заходим в меню программы Файл/Открыть. Или воспользуемся горячими клавишами ( CTRL+O).  После чего появится стандартное окно проводника для указания пути к изображению. Находим нужную картинку и щёлкаем по ней два раза левой кнопкой мыши. После чего в рабочей области окна Фотошоп появится выбранная картинка.

Шаг 2:

Заходим в меню программы Изображение/Размер изображение (CTRL+ALT+I). Перед нами откроется окно настройки размеров изображения:

ps-blog.ru

В этом окне мы видим информацию об изображение. В моём случае это: размер (вес) изображения 737,5К,  размер по ширине 204,6 мм, по высоте 153,1 мм, разрешение 72 пикселы/дюйм. В этом уроке мы будем уменьшать наше изображение, поэтому в поле «Ресамплинг» ставим галочку и выбираем «Бикубическая (с уменьшением)» Если вам нужно увеличить изображение, то выбираем «Сохранить детали (с увеличением)».

Затем вручную указываем ширину и высоту. Например, указав в поле «Ширина» значение 150 мм, значение «Высота» автоматически пропорционально выставляется равным 112,24 мм. Тоже самое произойдёт, если вначале указать высоту. Если второе значение автоматически не выставилось, то проверьте наличие галочки напротив значения «Ресамплинг», если ее нет, то выставьте ее и заново вбейте одно из значений.

Также обязательно обратите внимание на выставленные единицы измерения, представленные в выпадающем списке справа от значений, в моём случае это – «мм». Вы же, можете выбрать любые значения, которые вам больше нравятся (мм, см, пикселы, проценты, дюймы и т.д.).

Уменьшать значение разрешения не рекомендуется, так как ухудшается качество изображения, а увеличение этого значения в нашем случае не улучшит качество изображения, а только увеличит вес самой картинки. Поэтому оставляем значение «Разрешение» без изменений и нажимаем кнопку «ОК». Если по какой-то причине, вы не хотите сохранять пропорции исходной фотографии по длине и ширине, то снимите «птичку» с Ресамплинг (сохранить пропорции).

Шаг 3:

Итак, мы получили изображение 150 мм х 112,24 мм. Теперь необходимо закрепить полученный результат, для чего сохраним все наши изменения. Если изображение будет опубликовано в интернете, то идём в меню Файл/Сохранить для Web…(CTRL+

ALT+SHIFT+S). Либо сохраняем в формате JPEG (или в любом другом) с наилучшим качеством, идём в меню Файл/Сохранить как…(CTRL+SHIFT+S).

ps-blog.ru

Вот таким образом меняется размер изображения. Чтобы хорошо усвоить этот навык, обязательно потренируйтесь на нескольких фотографиях.

Разрешение и качество изображения

Качество изображения не пострадает, если уменьшать её в размерах. Важный нюанс при использование инструмента «Размер изображения» заключается в следующем: нельзя из изображения с меньшим разрешением получить точно такое же изображение без потери качества, но с большим разрешением.

Например, если взять нашу картинку и уменьшить её скажем до размера 100 мм на 74,83 мм, а потом полученный результат увеличить до разрешения 204,6 х 153,1 то в итоге увидим следующее:

ps-blog.ru

Вместо:

ps-blog.ru

Давайте разберемся, почему это происходит. Когда вы открываете растровое изображение (JPEG) в редакторе, в нашем случае это Фотошоп, и «уменьшаете в размерах картинку», то программа из файла изображения просто отбрасывает часть информации (пиксели). И делает это Фотошоп, кстати, лучше всех (Сохранить для Web, JPEG).

P.S. Надеюсь данный урок вам понравился, а полученные знания пригодятся. Понравилась статья — поделитесь с друзьями.

До встречи в следующем уроке!

 

90000 How to crop and resize images 90001 90002 Learn how to resize an image, crop and straighten, and add to the image canvas in Adobe Photoshop. 90003 90002 Change the size of an image. 90003 90002 Let’s talk about how to change the size of an image in Photoshop. I suggest that you start with this image from the downloadable practice files for this tutorial. I’d like to set the size of this image, so that it’s a good fit for posting to a particular website, where I happen to know, that the ideal image size is 900 pixels wide.Before we resize this image, let’s check how big it is to start with. In most cases, you’ll want to start with an image that’s bigger than or at least not a lot smaller than the resized image that you need. That’s because, if you enlarge an image a lot, at some point, it can start to look blurry. I’ll go down to the status bar at the bottom of the Document window, and I’ll click and hold on the document size information. In the small window that pops up, we can see that this file is 1 800 pixels wide by 1200 pixels high.Since we want to put it in a spot that’s only 900 pixels wide on our website, that means we’ll be scaling it down. To resize this image, I’ll go up to the Image menu, and I’ll choose Image Size … That opens the Image Size dialog box. If you like, you can make this window bigger by going to the bottom right corner and dragging out. Over on the left, you can see a preview of the image and on the right, are the controls for changing image size. There’s a lot of information here, but you do not have to work through all of it, particularly when you’re resizing an image that will be viewed on the screen as opposed to print.As we are in this example. So, there’s just a couple of things to check here. First, make sure that this Link icon is on. This is what it looks like when it’s on. If I click it, this is what it looks like when it’s off. So, we want it on, to make sure that the Width is linked to the Height, so that when we resize the image, the original proportion of width to height is preserved and the image does not look squeezed or stretched. Second, make sure that there’s a checkmark in this box, the Resample box.When this box is checked, you’re telling Photoshop that it’s OK to throw away some pixels when it makes this image smaller. Or if you were making the image bigger, to add some pixels. And third, take a look over to the right of the Width and Height fields, where you can see the unit of measurement that’s being used to report the dimensions of the image. By default, this is set to inches. But when you’re sizing an image for use on-screen as we’re doing in this example, the correct unit of measurement is not inches, it’s pixels.So, I’m going to click on either of these 2 menus, and change it from Inches to Pixels, and the other menu changes too because the Width and Height are linked. Now it’s time to change the size. I’ll go to the Width field and instead of 1800 I’ll type 900. You can see that the Height field automatically changed, and it changed proportionately. Now, here’s a bonus tip: if you wanted an image to have different proportions, say 900 by 400, rather than 900 by 600 in this case, the best way to achieve that would be to use another tool, the Crop tool, which we ‘re going to cover in another movie.Before I click OK, you may be wondering why I did not change the Resolution field. That’s because this Resolution field is only relevant when you’re preparing an image for print. When you’re sizing an image for on-screen use, as in this example, the number in this field really does not affect the dimensions of the image. So, you can leave it set to whatever it happens to be. So, after making those few changes in the Image Size dialog, we can now come down to the OK button and click there to close the Image Size dialog box and take us back to the Document window.If you like, you can go back to the Status bar and check the size of the resized image. I’ll click and hold on the information there and you can see that we now have a 900 by 600 pixel image instead of the original which was 1800 by 1200. All that is left to do, is to save the image. I’ll go up to the File menu, and I’m going to choose Save As … rather than Save because I do not want to save over the original 1800 by 1200 pixel version. So, in the Save As dialog, I’m going to give this version another name.You can type anything you want here. I’m going to type «Resize-web.jpg» for my web sized version of the file. I’ll leave everything else as it was and I’ll click Save. I’ll click OK in the JPEG options window, and now we’re done. So that’s how to resize an image for on-screen use in Photoshop’s CC Image Size dialog box. 90003 90002 90003 90002 90011 What you learned: To resize an image 90012 90003 90014 90015 Choose 90011 Image> Image Size 90012.90018 90015 Measure width and height in pixels for images you plan to use online or in inches (or centimeters) for images to print. Keep the link icon highlighted to preserve proportions. This automatically adjusts the height when you change the width and vice versa. 90018 90015 Select 90022 Resample 90023 to change the number of pixels in the image. This changes the image size. 90018 90015 Click OK. 90018 90027 90002 Change the resolution of an image.90003 90002 If you like to print images, it can be useful for you to have a basic understanding of what image resolution means in Photoshop, and how to change the resolution of an image to prepare it for print. That’s done in the Image Size dialog box. If you’re following along, let’s open this image, that you’ll find in the practice files for this tutorial. And then go up to the Image menu, and choose Image Size … In the Image Size dialog box, you can see the Dimensions of this image reported in pixels.When an image is still on your computer, that’s how we measure its size, in pixels. But if we were to print this image, we would measure the size of the print in inches, not pixels. Down here in the Resolution field, you can see the resolution that’s currently set for this image, it’s 100. There’s nothing special about a resolution of 100, it’s just a round number that I picked when I set up the file for this lesson. Now, what does Resolution mean here? Well, if you read across this line from left to right, you may get a sense of it.This is telling us that resolution is a particular number of Pixels / Inch, in this case 100 Pixels / Inch. Another way to say that, is that if and when you print this image, 100 pixels out of the total 1800 across and the total 1200 down, will be assigned to every printed inch, horizontally and vertically. Now if you do not like math problems, you can skip the next part, but if you like to think of this in terms of math, here’s a simple example. So, the math problem is: divide 1800 by 100 and you get 18.That means that at resolution of 100 pixels per inch, this file will print at 18 inches across. And it works the same way vertically. If we divide the total, 1200 pixels of height into groups of 100, that gives you 12 groups or 12 inches. So, the height of the printed image will be 12 inches. So, if you understand that basic concept, now you’re probably wondering, well what’s the best number to put in the Resolution field when you’re preparing an image for print? Unfortunately, there’s no one answer because that depends on what printer you’re using.But assuming you’re printing at home on a typical inkjet printer, it’s fair to say, that a resolution of about 300 pixels per inch will do. If I were to print the image with only 100 pixels per inch, it might look OK, but if you got really close to it, it would not look its best. Because my desktop inkjet printer really needs around 300 pixels per inch. So how do you go about changing the resolution of a printed image to 300 pixels per inch in this dialogue box? The first step is to make sure that the Resample box is unchecked.Because if we’re just changing the resolution, we probably do not want to change the total number of pixels in the file. And that’s what Resample does. So, let’s say that we want the total number of pixels in the file to remain at 1 800 by 1200. We just want to reallocate them into groups of 300 rather than groups of 100. So, what I’m going to do is type 300 in the Resolution field. Spoiler alert: when I do that, the number of inches in the Width and Height fields will change too. So, let’s go ahead and type 300 here.And sure enough the Width and Height have changed from 18 inches and 12 inches, to 6 inches by 4 inches. And that’s the size at which this image will print with the necessary resolution to make the best print. I’m done here, so I’m going to click OK. That closes the Image Size dialog box and takes me back out to the Document window. And here I have an image ready to save and print at 6 inches by 4 inches, with 300 pixels in every inch. 90003 90002 90003 90002 90011 What you learned: To change image resolution 90012 90003 90014 90015 Choose 90011 Image> Image Size 90012.Resolution in this dialog box means the number of image pixels that will be assigned to each inch when the image is printed. 90018 90015 Leave width and height set to inches for printing. 90018 90015 Deselect 90022 Resample 90023 to preserve the original number of image pixels. 90018 90015 In the 90022 Resolution 90023 field, set the number of pixels per inch to 300 for printing to a typical desktop inkjet printer. This changes the number of inches in the width and height fields. 90018 90015 Click OK.90018 90027 90002 The Crop tool is one of Photoshop’s CC most useful tools, particularly for those of you who take lots of photographs. You can use it to improve a composition and to straighten crooked photos. I’ve opened this photo from the practice files for this tutorial. So, I can show you the basics of the Crop tool. I’ll start by selecting the Crop tool here in the Tools panel. As soon as I do, you can see this border around the whole image. That’s the Crop box.I’ll move my cursor over any of the corners or any of the edges of the Crop box and drag to reshape that box. So, in this case, I might drag it way in to create a very different composition than the original photograph. As you create your crop, Photoshop shows you a preview with the areas to be cropped away shaded in gray. That way you can evaluate what it is you’re about to eliminate before you finalize the crop. Now, before I finalize this crop, I want to go up to the Options bar to show you an important option there.And that is Delete Cropped Pixels. That option is checked by default. I usually like to uncheck that. Because when Delete Cropped Pixels is checked, if you finalize the crop and save the image, you’ll permanently delete the cropped away pixels. But, with this option unchecked, you can bring back the cropped away pixels at any time. Let’s give it a try. I’m going to finalize this crop by going over to the big Checkmark in the Options bar and clicking there. Now, there are other ways to finalize a crop, but I like this way because it’s very simple.So now you can see the photo with the crop applied. Let’s say that I’m doing something else with the image and then, I change my mind about the way I’d cropped it. At any time, I can go back and select the Crop tool and then click on the image again, and all the pixels that I cropped away appear back in view and I can change my crop. This time I might include some of those cropped away pixels. By the way, you may have noticed that there’s a grid of vertical and horizontal lines on top of my photo as I use the Crop tool.This overlay presents a classic compositional technique known as the rule of thirds. The idea of ​​this technique is that if you place the important content in an image at the intersection of any of these horizontal and vertical lines you may improve the composition. Let’s give it a try with this image. I’m going to place the bouquet right at this intersection by clicking on the image and dragging and placing it here. And then I might reshape the crop boundary a little more, pulling it in tighter on this bouquet.And then I’ll click the Checkmark. Again, I’m going to click on the image with my Crop tool to try to fine-tune this crop a little more. I notice that this image is a little crooked, especially down here at the table. One of the things you can do with the Crop tool is straighten an image. There are a couple of ways you can do that. You either can move your cursor outside of one of the corners and manually try to drag to straighten the image, and this grid appears that helps you do that. I prefer the automatic method.So, I’m going to undo, that’s Command + Z on the Mac, Ctrl + Z on the PC. So, the image is crooked again and then I’ll go up to the Options bar and I’m going to use the automatic straighten tool. I’ll click on that tool to select it in the Options bar for the Crop tool. I’ll move into the image, and then I’m going to click along the edge of this table, hold my mouse down, and drag a little way further along that edge. Now you do not have to go all the way along with the edge. Sometimes just a little bit will do the trick, like this.And Photoshop uses your line as a guide to rotate the image so that the content looks straight. I’m going to fine-tune this crop a little more, maybe bringing up this edge and maybe moving the bouquet over a bit to put it right in the center. And then I’m going to go up to the Options bar and click the Checkmark to finalize my crop. So those are some of the basics of the Crop tool. I hope you give these techniques a try to work on your own compositions in Photoshop. 90003 90002 90003 90002 90011 What you learned: To crop and straighten an image 90012 90003 90014 90015 Select the 90022 Crop 90023 tool in the 90022 Tools 90023 panel.A crop border appears. 90018 90015 Drag any edge or corner to adjust the size and shape of the crop border. 90018 90015 Drag inside the crop border to position the image inside the crop border. 90018 90015 Drag outside a corner of the crop border to rotate or straighten. 90018 90015 Click the check mark in the options bar or press Enter (Windows) or Return (macOS) to complete the crop. 90018 90027 90002 Add some space to the document canvas.90003 90002 There may be times when you want to add to your document canvas, so there’s more room to add elements like text or images to your design. You can do that by using the Canvas Size command which we’ll look at in this lesson. If you’re following along, you can use this image from the practice files for this tutorial or an image of your own. To add to the canvas around this image, I’ll go up to the Image menu, where there is a Canvas Size … command right below the Image Size… command. Now, just to keep these 2 straight, the Image Size command …, which we looked at in another video in this tutorial, works differently than the Canvas Size … command. Unlike Image Size …, Canvas Size … does not change the size of your actual photos or other artwork or images in a composition. It just lets you add space around those items. So, let’s select Canvas Size … And that opens the Canvas Size dialog. At the top of this dialog, you can see the Width and Height of this image in Inches.And down here you can add to the Width of the canvas or add to the Height of the canvas or both. And those fields are set to Inches by default also. But when you’re preparing an image for online use, rather than for print, it makes more sense to change this unit of measurement to Pixels because that’s the way we measure and talk about the size of images on screen, as you learned earlier in this tutorial. So, I’m going to change either one of these menus from Inches to Pixels. And the other menu changes too.If you know the total width in pixels that you want the image to be after expanding the canvas, you could type that number here in the Width field. But it’s often easier to just tell Photoshop how many pixels to add to the canvas without worrying about what the total will be. To do that, come down here and click the Relative checkbox. That sets the number in the Width and Height fields to 0. And now, I can type in the number of pixels that I want to add to the canvas. So, let’s say that I want to add 400 pixels to the width of the canvas.I’ll type 400 here. If I wanted to add to the height of the canvas, I could do that too. I’m just going to leave that at 0 for now. And then I’ll click OK to apply that. And out in the Document window, you can see that Photoshop added canvas to both the left and the right sides of this photo. What it did was split the 400 pixels of extra width that I asked it for, into 200 pixels on the right and 200 pixels over here on the left. Well, what if I wanted to add canvas to just one side of this image.Let’s say over here to the right side. That’s done slightly differently. So, let’s undo what we’ve done so far, try that instead. I’ll press Command + Z on the Mac, Ctrl + Z on a PC to undo. And I’ll go back to the Image menu and choose Canvas Size … again. The first thing I’m going to do here is to check that the Width and Height fields are still set to Pixels. And they’re not, they’ve reverted to the default Inches. So again, I’ll change those menus to Pixels. And I’ll double check that Relative is checked.As I said, I want the added canvas to appear just on the right side of this image. To do that, I’ll go down to this anchor diagram and I’m going to click on the middle box on the left side of this diagram. What that does is tell Photoshop to pin or anchor the image to the left side of the canvas, and put the extra canvas to its right. So now I’m going to go up to the Width field, and I’m going to type in the number of pixels that I want to add to the right side of this image. Let’s add 800 pixels.And click OK. And that’s exactly the effect that I wanted. You probably noticed that so far, my canvas extensions have all been white. But you can control the color of your canvas extension, here in the Canvas Size dialog, using the Canvas extension color menu here. By the way, if you’re working on another image, and you’re not on a special background layer, as we are in this image, then your Canvas extension color menu will be unavailable and the canvas that you add will be transparent. It will appear like a gray and white checkerboard in Photoshop.I’m just going to click Cancel. And, if I want to save this image, I’ll go to the File menu and I’ll choose Save As …, so I do not save over my original. So that’s how you can add space to your document canvas, so you have some extra room to add more image elements. 90003 90002 90003 90002 90011 What you learned: To change canvas size 90012 90003 90014 90015 Choose 90011 Image> Canvas Size 90012 90018 90015 To add a canvas, enter the amount of width and height to add.Measure width and height in pixels for online use or in inches for print. 90018 90015 Select 90022 Relative 90023, and then select an anchor point in the canvas diagram. The arrows point to the sides where the canvas will be added. 90018 90015 Click OK. 90018 90027 .90000 Resizing Images To Match Photo Frame Sizes With Photoshop CS6 90001 90002 90002 90004 Written by Steve Patterson. 90005 90004 In this tutorial, we’ll look at one of the most common issues that photographers and Photoshop users run into when resizing images for print — how to resize them to fit within a certain size picture frame when the aspect ratio of the photo and the frame are different. 90005 90004 Most photos captured with a digital camera today can easily be resized to print as a 4 «x6» or 8 «x12», perfect for displaying in, well, 4 «x6» or 8 «x12» frames.But obviously (and thankfully) not all frames are 4 «x6» or 8 «x12». What if you want to display your image as a 5 «x7», an 8 «x10», 11 «x14» and so on? How do you resize the image to print in these different aspect ratios without squishing, stretching or in any way distorting the look of the original? You may have already discovered that there’s no way to do that in Photoshop’s Image Size dialog box. As we’ll learn in this tutorial, what we actually need is a two-step process involving both the Image Size command and Photoshop’s Crop Tool.Yet even though there’s a bit more to it, reshaping an image for a specific frame size is easy. When you’re done with this tutorial, you’ll be able to print your photos for display in any size frames you choose! 90005 90004 I’ll be using Photoshop CS6 here. To get the most from this tutorial, you should already have a basic understanding of how to resize images. If you’re not familiar with image resizing, you’ll first want to read through our How To Resize Images In Photoshop tutorial before you continue.I also suggest reading our Cropping Images in Photoshop CS6 tutorial for a more detailed explanation of how the Crop Tool works as well as its new features in CS6. 90005 90004 Download this tutorial as a print-ready PDF! 90005 90014 The Aspect Ratio Problem 90015 90004 Before we learn how to change the print size and aspect ratio of an image, let’s take a quick look at the problem. Here’s the photo I currently have open on my screen (holiday family portrait photo from Shutterstock): 90005 90018 90018 90004 The original image.90005 90004 Let’s say I want to print an 8 «x10» version of this photo. I’ll try resizing it the way I would normally resize an image, and that’s by using Photoshop’s Image Size command. To get to the Image Size command, I’ll go up to the 90023 Edit 90024 menu in the Menu Bar along the top of the screen and choose 90023 Image Size 90024: 90005 90028 90028 90004 Going to Edit> Image Size. 90005 90004 This opens the Image Size dialog box. Again, if you’re not familiar with this dialog box or how to resize images in general, be sure to read through our How To Resize Images In Photoshop tutorial first: 90005 90034 90034 90004 The Image Size dialog box in Photoshop CS6.90005 90004 Since I’m only interested in changing the print size of the image, I’ll uncheck the 90023 Resample Image 90024 option. This way, I will not be changing the actual number of pixels in the image (a process known as resampling). I’ll only be changing the size at which it will print: 90005 90042 90042 90004 Unchecking the Resample Image option. 90005 90004 We control the print size of an image using the 90023 Document Size 90024 section of the dialog box. At the moment, it’s telling me that my image will print 14 inches wide by 9.333 inches tall at a resolution of 300 pixels per inch: 90005 90050 90050 90004 The current print size of the image (14 inches x 9.333 inches). 90005 90004 I want to print the image as an 8 «x10» (or more specifically, a 10 «x8»), so I’ll change the 90023 Width 90024 value from 14 inches to 90023 10 inches 90024. When changing the print size, Photoshop always tries to maintain the original aspect ratio of the image so we do not distort its appearance, and it does this by automatically changing the other value for us.For example, we see here that when I changed the Width value to 10 inches, Photoshop went ahead and automatically entered a new Height value for me to keep the aspect ratio the same. Unfortunately, that meant setting the height to 90023 6.667 inches 90024. I want to print the image as a 8 «x10», not a 6.667 «x10», so this did not give me what I needed: 90005 90062 90062 90004 Changing the Width to 10 inches set the Height to only 6.667 inches. Not what I wanted. 90005 90004 No worries, I’ll just change the 90023 Height 90024 value myself from 6.667 inches to 90023 8 inches 90024. Did that work? Nope. Photoshop went and changed the Width value on me from 10 inches to 90023 12 inches 90024, again to keep the photo’s original aspect ratio intact: 90005 90074 90074 90004 Changing the Height to 8 inches set the Width to 12 inches. Also not what I wanted. 90005 90004 Whether I change the Width or the Height value, it makes no difference. Photoshop keeps changing the other value to something other than what I need. The culprit is the photo’s 90079 aspect ratio 90080 — the relationship between the width and height of the image.Its current ratio will not allow it to fit within an 8×10 (or 10×8) shape, and there’s nothing I can do about that here in the Image Size dialog box. So, I’ll accept my defeat (for now) and click the 90023 Cancel 90024 button to close out of it: 90005 90084 90084 90004 Clicking the Cancel button. 90005 90014 Step 1: Duplicate The Image 90015 90004 The first thing we need to do, then, is change the aspect ratio of our image so it 90079 will 90080 fit within the shape we need. But before we do that, let’s duplicate the image so our original remains safe and unharmed.To duplicate it, I’ll go up to the 90023 Image 90024 menu at the top of the screen and choose 90023 Duplicate 90024: 90005 90098 90098 90004 Going to Image> Duplicate. 90005 90004 Photoshop opens the Duplicate Image dialog box where we can give the copy a specific name or just accept the default name (which is what I’m going to do). If your original document contains multiple layers, you’ll want to check the 90023 Duplicate Merged Layers Only 90024 option to have Photoshop merge all the layers onto a single layer.In my case, since my document contains just one layer, the option is grayed out. Click OK when you’re done: 90005 90106 90106 90004 The Duplicate Image dialog box. 90005 90004 Photoshop makes a copy of the image and opens it in its own separate document with its name appearing in the tab along the top. We can now safely resize our image without worrying that we’ll accidentally overwrite the original: 90005 90112 90112 90004 The duplicate image appears in a separate document. 90005 90014 Step 2: Select The Crop Tool 90015 90004 To change the aspect ratio, we can use Photoshop’s 90023 Crop Tool 90024.I’ll select the Crop Tool from the Tools panel along the left of the screen (or I could simply press the letter 90023 C 90024 on my keyboard to access it with the handy shortcut): 90005 90124 90124 90004 Grabbing the Crop Tool. 90005 90014 Step 3: Enter Your New Aspect Ratio 90015 90004 The Crop Tool in Photoshop CS6 gives us several different aspect ratio and crop size presets to choose from using the 90023 Presets 90024 option near the far left of the Options Bar along the top of the screen, but I find the easiest thing to do here is simply leave this option set to 90023 Original Ratio 90024: 90005 90136 90136 90004 Setting the Presets option to Original Ratio.90005 90004 This way, I can enter the exact aspect ratio I need into the 90023 width and height boxes 90024 directly to the right of the Presets option. Since I need to create an 8 «x10» version of the image, with the width being the larger of the two dimensions, I’ll click inside the first box on the left (the width) and enter a value of 90023 10 90024. Then I’ll click inside the second box (the height) and enter a value of 90023 8 90024. There’s no need to enter a measurement type, like «in» for inches, since all we’re doing is setting the aspect ratio itself, not actual measurements: 90005 90148 90148 90004 Entering a new aspect ratio of 10: 8.90005 90014 Step 4: Resize The Crop Box As Needed 90015 90004 In Photoshop CS6, selecting the Crop Tool automatically places a 90023 crop box 90024 around the image, and as soon as we enter a new aspect ratio into the Options Bar, Photoshop instantly reshapes the crop box to match the new ratio. The area inside the crop box is what we’ll be keeping, while everything outside the box will be cropped away: 90005 90158 90158 90004 Photoshop adds a crop box and reshapes it to the new aspect ratio.90005 90004 You can resize the crop box as needed by clicking and dragging any of its four sides or its four corners. Regardless of which side or corner you’re dragging, the aspect ratio of the box will remain locked in place. All we can do is resize it, making it larger or smaller. You can also move the image around inside the crop box to reposition it by clicking and dragging anywhere inside the box. Here, I’ve made the crop box just a bit smaller than it was initially by dragging the bottom left corner inward, then I clicked and dragged the image inside the box towards the left to center the family inside of it: 90005 90164 90164 90004 Resizing the crop box and repositioning the image inside it.90005 90014 Step 5: Turn The «Delete Cropped Pixels» Option Off 90015 90004 Before we actually crop the image, there’s one more thing we should do, and that’s make sure the 90023 Delete Cropped Pixels 90024 option in the Options Bar is not selected (unchecked). Photoshop CS6 gives us the choice of either deleting the pixels we crop away or simply hiding them. The advantage with hiding them is that it’s non-destructive. We can easily come back later, reselect the Crop Tool, and then resize or reposition the crop box.This can be a handy feature if you realize later in the Image Size dialog box that you’ve cropped the image too small to print at larger sizes. We’ll come back to this topic at the end of the tutorial, but for now, simply make sure Delete Cropped Pixels is unchecked: 90005 90174 90174 90004 Leave Delete Cropped Pixels turned off. 90005 90014 Step 6: Crop The Image 90015 90004 When you’re happy with the size and position of the crop box, press 90023 Enter 90024 (Win) / 90023 Return 90024 (Mac) on your keyboard to accept it and have Photoshop crop the image to your new aspect ratio (to then remove the crop box from around the image, simply select any of the other tools in the Tools panel): 90005 90186 90186 90004 The image after cropping it to its new aspect ratio.90005 90014 Step 7: Select The Image Size Command 90015 90004 Now that my image has been cropped to its new aspect ratio, I’ll reselect Photoshop’s Image Size command by going up to the 90023 Image 90024 menu at the top of the screen and choosing 90023 Image Size 90024: 90005 90198 90198 90004 Going back to Edit> Image Size. 90005 90014 Step 8: Uncheck The Resample Image Option 90015 90004 When the Image Size dialog box opens, I’ll again uncheck the 90023 Resample Image 90024 option at the bottom so I’m only changing the print size, not the number of pixels in the image: 90005 90208 90208 90004 Unchecking the Resample Image option.90005 90014 Step 9: Change The Width And Height 90015 90004 This time, after cropping the image, the Document Size section is telling me that my photo will print 11.167 inches wide by 8.933 inches high, again at a resolution of 300 pixels per inch: 90005 90216 90216 90004 The initial print size after cropping to the new aspect ratio. 90005 90004 Since I need an 8 «x10» print, I’ll change the 90023 Width 90024 value to 90023 10 inches 90024, just like I did earlier. And just like Photoshop did earlier, it maintains the aspect ratio of the image by automatically changing the other value for me.Yet this time, because I used the Crop Tool to crop the photo to its new aspect ratio before opening the Image Size dialog box, Photoshop is able to set the Height value to 90023 8 inches 90024, giving me the exact print dimensions I need: 90005 90228 90228 90004 Cropping the image first made it easy to resize it for print. 90005 90014 The Resolution Value 90015 90004 One very important thing you’ll want to keep an eye on as you’re resizing the image for print, especially after cropping it, is the 90023 Resolution 90024 value.This tells us how many of the pixels in the image your printer will squeeze into every inch of paper. Generally, higher resolution values ​​produce sharper, more detailed images because we’re printing more pixels per inch and packing more detail into the area. You’ll find the Resolution value directly below the Width and Height options in the Document Size section. Here, it’s telling me that after resizing my image to an 8 «x10», it will print at a resolution of 335 pixels per inch. Your resolution value may show something different: 90005 90238 90238 90004 The current print resolution of the image.90005 90004 Again generally speaking, for high quality, professional looking prints, you’ll want your resolution value to be no lower than around 90023 240 pixels per inch 90024. Higher than that is great, but if you go much below that, your printed image will not look as crisp and sharp as you expected. If you do find your resolution value dropping below 240 pixels per inch, it may be because you cropped too much of the original image away, with not enough pixels remaining to print a high quality version at the size you need.In that case, you may want to cancel out of the Image Size dialog box, then go back, reselect the Crop Tool and re-adjust your crop box, this time keeping more of the original photo and cropping less of it away (this is why we made sure the Delete Cropped Pixels option was turned off back in Step 5). 90005 90004 Or, if it’s still too small and you absolutely need to print it at the larger size, you can enlarge the image by resampling it. You’ll find more information on resampling images in our Image Resolution and Print Quality tutorial as well as our Difference Between Image Resizing and Resampling tutorial.But again, as long as the Resolution value remains around 240 pixels per inch or higher after entering your new width and height, you can click OK to close out of the Image Size dialog box and you’re good to go! 90005 90004 And there we have it! That’s how to resize and reshape an image to print in any aspect ratio you need using the Crop Tool and the Image Size dialog box in Photoshop CS6! 90005 90014 Subscribe to our newsletter 90015 90004 Be the first the know when new tutorials are added! 90005 90254 .90000 How To Resize Images in Photoshop 90001 90002 90002 90004 Written by Steve Patterson. 90005 90004 Resizing an image is one of the most commonly used skills in all of Photoshop. It’s so common, in fact, that even people who know virtually nothing about Photoshop still manage to use it to resize their images, which should give you an idea of ​​how easy it is to do. 90005 90004 In this tutorial, we’ll learn how to resize images, as well as a general rule to keep in mind so your resized photos remain crisp and sharp.I’ll be using Photoshop CS5 here but the steps are the same with any recent version of the program. 90005 90004 Download this tutorial as a print-ready PDF! 90005 90004 Here’s an image I have open on my screen: 90005 90014 90014 90004 The original photo. 90005 90004 This is a photo taken on a trip to Mexico. Of course, the original version of the photo was much larger than what we’re seeing here, but I’ve resized it and made it smaller so it fits better on the page. How did I do that? It’s easy.To resize an image in Photoshop, we use the 90019 Image Size 90020 command which we can get to by going up to the 90019 Image 90020 menu in the Menu Bar along the top of the screen and choosing 90019 Image Size 90020: 90005 90026 90026 90004 Go to Image> Image Size. 90005 90004 This will bring up the Image Size dialog box, as shown below: 90005 90032 90032 90004 The Image Size dialog box. 90005 90004 This screenshot of the Image Size dialog box was taken immediately after I opened the original photo, before I resized it to a smaller version for displaying on the page.If you look closely, you’ll notice that the dialog box is divided into two main sections — 90019 Pixel Dimensions 90020 and 90019 Document Size 90020 — each showing different measurements. Since this tutorial is all about how to resize an image, we only need to concern ourselves with the top section, Pixel Dimensions, since it’s the one that controls the actual, physical dimensions (in pixels) of the photo. 90005 90004 Let’s look more closely, then, at the Pixel Dimensions section, which tells us two things about our image.First, if we look directly to the right of the words «Pixel Dimensions», we can see the current 90019 file size 90020 of the image. In my case, it’s telling me that my photo is 90019 14.6 M 90020 (the «M» stands for megabytes, or «millions of bytes»): 90005 90048 90048 90004 The current file size is displayed to the right of the words «Pixel Dimensions». 90005 90004 Knowing the file size of the image can be useful if you want to compare the size of the original version with the resized version, but it does not help us actually resize our image.For that, we need the other bit of information that the Pixel Dimensions section is telling us — the current 90019 Width 90020 and 90019 Height 90020 of our image: 90005 90058 90058 90004 The current width and height of the image, in pixels. 90005 90004 Here, we see that my original photo was 2608 pixels wide by 1952 pixels high. At that size, I’d have no problem printing a great looking 8×10, but I needed a smaller version, one that would fit better on these pages. So how did I make it smaller? I simply changed the numbers in the Width and Height boxes to what I needed! I’ll set the new width for my image to 900 pixels and the height to 647 pixels (of course this is just an example, you can enter whatever size you need): 90005 90064 90064 90004 Entering new Width and Height values ​​for the image.90005 90004 To change the Width and Height values, simply 90019 double-click 90020 inside one of the two boxes (either Width or Height), which will highlight the number currently showing in the box, and then type a new value. When you’re done, click the OK button and Photoshop will resize your image to the new dimensions you’ve specified. 90005 90004 You can also resize your image by a percentage of the original image size rather than typing in a specific pixel value. If you look to the right of the Width and Height value boxes, you’ll notice that the measurement type is currently set to 90019 pixels 90020, but if you click on either the word «pixels» or the arrow to the right of the word , a drop-down menu will appear which lets you change the measurement type to 90019 percent 90020: 90005 90078 90078 90004 Changing the measurement type from pixels to percent.90005 90004 Once you’ve chosen percent as your measurement type, the Pixel Dimensions section will display the width and height of your image as a percentage rather than a pixel value. Resizing the image using a percentage is done the same way as if you were using pixel values. Just 90019 double-click 90020 inside the Width or Height value box and type in a new percentage. When you’re done, click the OK button and Photoshop will resize the image to whatever percent value you entered. 90005 90004 You’ll notice, unless you’ve changed the default settings, that when you enter in a new Width or Height value, the other value changes automatically.In other words, if you try to change the value for the width of your image, the height will change along with it. That’s because by default, Photoshop keeps the original aspect ratio of the image intact when you resize it, which is usually what you want. Normally, you would not change the width of a photo without changing the height as well, otherwise things will look distorted. Photoshop lets us know that the width and height values ​​of the image are currently linked together by displaying a 90019 linked icon 90020 to the right of the values: 90005 90090 90090 90004 This icon tells us that the Width and Height values ​​are currently linked together.90005 90004 If you look near the bottom of the Image Size dialog box, you’ll see the 90019 Constrain Proportions 90020 option which controls whether the width and height are linked. By default, the option is selected, but if you need to change the width and height separately, simply uncheck this option: 90005 90098 90098 90004 The Constrain Proportions option keeps the aspect ratio intact but can be disabled if needed. 90005 90102 Resizing And Image Quality 90103 90004 Resizing images in Photoshop may be easy, but there’s something very important to keep in mind when it comes to maintaining image quality.In general, it’s okay to make a photo smaller than its original size, but you want to avoid making it larger whenever possible. Let’s look at an example. 90005 90004 Let’s say I need to make the width and height of my photo smaller by 50 percent. To do that, in the Image Size dialog box, I’ll simply change both the Width and Height values ​​to 50 percent: 90005 90108 90108 90004 Reducing the size of the image. 90005 90004 I’ll click OK in the top right corner of the Image Size dialog box, at which point Photoshop closes the dialog box and resizes my image.Since I made both the width 90113 and 90114 height smaller by 50 percent, the photo is now one fourth of its original size: 90005 90116 90116 90004 The image after resizing the width and height by 50 percent. 90005 90004 As we can see, the photo is now much smaller but the overall image quality remains pretty consistent. Let’s see what happens, though, if I take this smaller image and try to enlarge it back to its original size. To do that, I’ll re-open the Image Size dialog box by going up to the Image menu at the top of the screen and choosing Image Size, then I’ll set both the Width and Height values ​​to 200 percent: 90005 90122 90122 90004 Changing the Width and Height values ​​to 200 percent.90005 90004 I’ll click OK to accept the values ​​and close out of the Image Size dialog box, at which point Photoshop enlarges the image, making it four times the size it was a moment ago: 90005 90128 90128 90004 The image after increasing its size by 200 percent. 90005 90004 Let’s compare the image quality of the enlarged version with that of the original version: 90005 90014 90014 90004 The original photo. 90005 90004 By enlarging the image, I’ve managed to return it to its original size, but when we compare the quality with that of the original, the enlarged version clearly does not look as good.We’ve lost a lot of detail in the image, and it’s starting to look soft and blurry. If I was to enlarge it even further, the image quality would grow progressively worse. 90005 90004 Here’s why. When you use the Image Size command to make a photo smaller, Photoshop makes it smaller essentially by throwing away pixels. It just takes some of the pixels from the image and tosses them out the virtual window. Fortunately, Photoshop is really good at knowing which pixels to throw away without sacrificing image quality, so making our images smaller is not usually a problem.90005 90004 The problem comes in when we ask Photoshop to make our images larger. If Photoshop makes them smaller by tossing pixels away, how do you think it makes them larger? If you answered, «By 90113 adding 90114 pixels to the image», you’d be right! But here’s the bigger question. Where does Photoshop get these new pixels from that it’s adding to the image? If you answered, «Um, I’m not sure. I guess it just kind of makes them up out of thin air», you’d be right again! 90005 90004 And therein lies the problem.When Photoshop makes an image larger, it has to add pixels that were not there before, and since Photoshop was not on the scene when you took the photo, it has no idea what a larger, more detailed version of the image should actually look like, which means it has to guess. Of course, Photoshop is a very powerful program and its guesses are based on some very complicated and advanced math, but at the end of the day, it’s still just a guess, and it’s not going to guess correctly. Bottom line, the larger you try to make your image, the worse your image is going to look.Instead of the sharp, highly detailed version you were hoping for, you’ll get something that looks dull, soft and blurry. 90005 90004 So again, when resizing your image, it’s okay to make your images smaller, but you should avoid making them larger at all cost unless you absolutely do not care about image quality. And really, who does not care about image quality? That’s just nonsense. 90005 90102 Subscribe to our newsletter 90103 90004 Be the first the know when new tutorials are added! 90005 90154 .90000 How to resize an image in Photoshop and keep best quality 90001 90002 In this tutorial, I’m going to address some things that a lot of people do not know.

On screen you see 90037 90038 pixels 90039 90040 of light and in print you see 90037 90038 dots 90039 90040 of ink. This is where the terms DPI (dots per inch) and PPI (pixels per inch) come from. In an over simplification, you can think of them as the same thing, however dots refer to print and pixels are a digital display.Many people mistakingly talk about DPI on screen, this is incorrect, but now you will know what they mean. DPI and PPI are both a way to describe 90037 90038 resolution 90039 90040. 90003 90002 You have heard the terms hi-resoluton, or low-resolution, or low-res. This means how dense are the pixels (or dots). More density = more resolution, or detail. If there is not enough resolution (image is not big enough) then you will see a noticeable softness to the image, or even jaggies (also called pixelization).Too much resolution, will not affect the image display quality, you will just have an unnecessarily large file. So let’s find the best resolution for your needs. 90003 90002 90053 90003 90002 The goal is to keep the quality as close to the original as possible and this article will show to how to do that. This is one of the big things that separate the pros from the amateurs, the quality of the final images. 90003 90057 Digital Resolution explained 90058 90002 Every screen has a native resolution, maybe its 750 x 1334 pixels or 326 ppi as the iphone retina.326 refers to 326 square pixels fit into 1 square inch of the display to perfectly match the screen size. But a better way to measure screen resolution is with overall pixels. 90003 90061 90023 For example many monitors (HD) are 1920 pixels across by 1080 pixels high. 1920 × 1080. 90024 90023 4K (Ultra HD) is 3840 x 2160. 90024 90023 A Canon 5d Mk4 camera is approx. 30 Megapixels (Mega = a million pixels). 6720 x 4480 pixels (6720 × 4480 = 30,105,600 pixels). 90024 90068 90057 Print Resolution explained 90058 90002 Print is measured in dots per inch (DPI) (LPI Lines per inch or line screen is used in commercial printing).If you have more dots in a square inch, you will have more resolution or detail in your print. Typical print resolution is 300dpi (some inkjet printers print better at 360 or 240 for example, look at your specs). This means that there are 300 dots of ink per square inch or printed material. If your image is less, it will look soft, if its larger, there is no benefit as a printer can not print beyond its maximum resolution. Ok, how to tell if it’s the right size? 90003 90022 90023 In Photoshop choose Image> Image size 90024 90023 Turn OFF resample.90024 90023 Enter your target resolution into the Resolution filed, in this case 300ppi (if you are targeting 300 DPI, PPI is the digital equivalent) 90024 90031 90002 You will now see that a 939 x 932 pixel image can print at 3.13 x 3.1 inches and look nice and sharp at 300ppi / 300dpi. If you need to it print larger you either need to select a larger image or scale the image up (resample). 90003 90002 90084 90003 90002 The problem with sampling up (enlarging) is that you will lose image quality.The larger you make it, the more quality you will lose. If you need to scale the image down (reduce) then the quality loss is not so much as issue, although you may need to sharpen an image if you shrink it too much (more about that soon). 90003 90013 How to describe an image size 90014 90002 If someone asks for an image of a certain size, just saying «4 × 6 inches» or «at 300dpi» does not give you enough information. Sometimes people even go as far as to say «300 dpi at 12Mb,» this does not help either because the file size does not really have bearing on the physical size of an image because file compression and file type all effect this.What you need to know id one of 2 things, either 90003 90022 90023 The overall pixel dimensions. Say 3000, 4000pixels. 90024 90023 Provide the target size AND resolution. For example, 4 × 6 inches at 300DPI / 300PPI. (See how to crop to an exact size and resolution) 90024 90031 90013 Resizing an Image and Photoshop Interpolation 90014 90002 When you change the size of the image, Photoshop has to recreate the pixels. Photoshop needs to know how to jam the pixels together and which ones to throw away when you scale down.It also needs to know how to create pixels when scaling up. This process is called 90037 resampling 90040. When you scale an image even by a single pixel, the entire image is resampled or rewritten. This is why creating the image at the correct size in the first place is great. However, do not fear, Photoshop does a really great job of resampling and many times you will never be able to see the difference in quality. 90003 90002 In order to resample, Photoshop has to do some math to know how to recreate pixels.This math is called 90037 interpolation 90040 (in-terpol-ation). Interpolation is important because certain types of interpolation will give you better results for different types of images. I’m going to attempt to keep this as non-technical in simple language and guide you to the best options. There were originally 3 types of interpolation in Photoshop (here is a non-scientific way for you to look at them). 90003 90061 90023 Nearest neighbor — Think of this as looking at the nearest pixel and matching its color and tone.90024 90023 Bi-linear — Think of this as looking at the 4 surrounding pixels and finding the average 90024 90023 Bi-Cubic — like looking at the 16 surrounding pixels and finding an average. But giving more weight to the 8 closest pixels. 90024 90068 90002 Typically bi-linear is best for line art and simple graphics, where are bi-cubic is best for photos and graphics containing gradients, but wait, it does not stop here. 90003 90002 90119 90003 90002 Adobe added 2 more types of Bicubic (In Photoshop CS3).They added: 90003 90061 90023 BiCubic Smoother: Smoothens out artifacts created in enlargements 90024 90023 Bicubic sharper: Sharpens to bring back lost details while reducing a file 90024 90068 90002 (See what features were added in which versions of Photoshop in our free superguides) 90003 90002 There are 2 more options what are they? 90003 90002 Automatic (Photoshop CS6), it selects Bicubic Smoother (CS6) / Preserve Details (CC) when enlarging and it chooses BiCubic Sharpener when reducing images.Automatic is easiest most of the time, but keep reading because it might not best the best option all the time. 90003 90013 Stair Step Interpolation 90014 90002 There is a «secret squirrel handshake» for experienced Photoshop users «in the know.» This secret is often credited to Fred Miranda, for discovering the stair step interpolation. It works like this, when you enlarge or reduce an image, rather than just jump to the final amount, scale it up or down at 10% at a time. You will see a marked improvement in your image sharpness and final quality 90037 90038 IF 90039 90040 you are using CS6 or the older interpolation algorithms.90003 90002 However, on testing I have found that Preserve Details produces the same result as stair step and I hazard a guess that some of that is built into the newest algorithm. This was one of the unsung heroes in the first release of Photoshop CC. 90003 90013 Ok Colin, enough! Which is the best resizing method to use? 90014 90002 Ok, this is where the rubber hits the road and it’s a good time for you to open the test image into Photoshop and test for yourself. You can also see me test it on the video above.90003 90002 I have found for upscaling that Preserve Details works really well for for many images, especially line art and graphics images (although for simple line art, sometimes bi-linear yields better results). However, sometimes for photographs bi-linear smoother can produce a more natural (although softer) results which has less halos and artifacts. You can always apply some sharpening to the result. The results depend on how much you are scaling up the image and also how detailed the image is vs large gradient areas such as skies in photos.So, do not just reach for auto. Try a couple of variations to see if you can coax better results out of Photoshop, sometimes you can. 90003 90013 Tips for scaling images in Photoshop 90014 90002 Ok, if you are still reading you are either a bit more advanced, or hungry to learn all you can. When you are scaling up or down images here are some tips to keep in mind. 90003 90061 90023 Always view images at 100%, there is no other way to tell the true quality as this is the only magnification that gives true feedback.90024 90023 Consider resizing the image twice, once for graphics, and another for photos and then combine the results. 90024 90023 Use resize presets if you are scaling images to a set size often 90024 90023 You can use Image Processor pro to batch process a lot of images. File> Automate> Image Processor Pro 90024 90023 Remember the interpolation methods are available for Image Processor Pro, Save For web, export as, as well as resize. 90024 90023 If you are needing to really enlarge an image look at some 3rd party plugins such as Alien Skins Blow up or OnOne’s perfect resize (formally known as Genuine Fractals) who 90037 claim 90040 they can scale images up to 1000x and still keep quality.90024 90068 90002 Thanks for checking out this tutorial / article.
