Resizing Images While Keeping Resolution

By David Peters

When you resize a large, sharp photo to a smaller size you may find that the new image has lost its sharpness. This is a common problem with changing the size of large, clear images. The blurry look can detract from the quality of the image.

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

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 method is extremely effective in keeping the sharpness of the image. You can set this as the default to make things easy for you by going to Preferences> General where you will see Image Interpolation. Select Bicubic Sharper as the default choice and it will be set as the default from now on.

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. - 15437
