TIP OF THE WEEK: How to change the image size of a photo in Adobe Photoshop
Teaching Photoshop for so many years, we’ve come across the same issues over and over again. One of the major problems especially for beginners is; how to re-size an image to 300 Pixels/Inch for print. Actually it is VERY simple: All a user has to understand is that Photoshop is based on pixels.
Simply pay attention to the “Pixel Dimensions” while changing the size of the image. The Pixel Dimensions should always remain the same! Reason: if Photoshop deletes Pixels or adds on Pixels, our image quality changes for the worse, gets blurry etc.
Step 1: Open the image in Photoshop CS6. Go to MENU > IMAGE > IMAGE SIZE.
Pay attention to the Pixel Dimensions which should remain the same. The Width and Height are linked together.
Step 2: Click off the Box “Resample Image” now the Width, Height and Resolution are linked together. Pay attention to the Pixel Dimensions on top. They are the same as before.
Step 3: Type in the Resolution field 300 Pixels/Inch for print. Notice that the Pixel Dimensions stay the same.
This means that we have changed the size of the image BUT, the Pixel Dimensions remain the same, so we have optimal quality for print.
Keep in mind that DPI is not PPI is not LPI and although there are many opinions as to the best re-sizing methods, one should at least utilize and compare the results of the 6 different re-sampling methods available at the bottom of the Photoshop image size dialog box, as the Automatic default setting “Bicubic Automatic” may not always be optimal.
