How To Use Photoshop - Maintaining Sharpness When Resizing Images

By 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.

This is a problem in many editing programs, but Adobe Photoshop has the tools to fix this.

You must have at least Photoshop CS to perform this function. The CS series is the most advanced software for editing images so you should get a copy. It is used by media professionals all over the world because of its unrivaled capabilities.

To make an image smaller go to Image - Image Size - Re-sample Image. Choose Bi-cubic Sharper from the resulting menu. This setting will minimize any blur that occurs when resizing the image.

When you want to increase the size of an image, but want to minimize the resolution loss choose Bi-cubic Smoother.

This process is so effective that I would recommend setting Bi-cubic 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 Bi-cubic Sharper as the default.

Remember that performing more than one re-size on an image will give it more blur. To experiment with the size that you want, use a duplicate image as multiple resizing will ruin the original image. Once you've found the size you want, you can apply the dimensions to the original image.
