Filter menu

There are too many filter tools to mention here. Under the Filter menu, you'll find a huge range of filter special effects, some of which are designed to lend an artistic look to your work. I use filters for jobs such as blurring pixels (depth-of-field effects) and some for distorting, sketching, stylizing, adding texture, and even for adding more digital noise. All filter effects can be used globally or simply applied to a smaller part of the image once they're confined inside a selection.

Correct Camera Distortion - Separate from the rest of the filters, Correct Camera Distortion is designed for correcting lens distortion. Use this to add or subtract optical errors, as well as creating a vignette and adjusting perspective.
