Resizing Images in Adobe Photoshop
David Peters
When you make an image smaller you may interfere with the resolution making the final image take on a blurry appearance. With large, clear images this can be devastating to the effect of the image.
Fortunately Adobe Photoshop has the ability to fix this issue with its advanced editing tools.
This method will only work in Photoshop CS and CS2. These versions are more powerful in a lot of ways, so if you don't have them I'd recommend that you invest in a copy as you may find that you will need the more advanced features.
To reduce the size of an image go to Image> Image Size. Select Resample Image and then select Bicubic Sharper from the menu. This is the optimal setting for reducing the blurring of the image when you resize it.
When you want to increase the size of an image, but want to minimize the resolution loss choose Bicubic Smoother.
This process is so effective that I would recommend setting Bicubic Sharper as the default selection when you start the software. You can do this by going to Preferences> General> Image Interpolation. Here you can select Bicubic Sharper as the default.
Repeating the resizing process too many times will increase the resolution loss giving a blurry appearance. To avoid this only resize the image once. If you want try out different sizes, use a copy of the original image and when you find the right measurements, simply apply them to the original image once you're done.
