When correcting an image for lens distortion the resulting image can be "pincushioned", that is the sides are caved-in and show as a transparent area.

Does anyone know of a way in Photoshop to "automatically crop" the image to remove the transparent zones? Using Trim does not work because the corners of the image extend out and prevent the transparent part from being removed.

the new cs5 has an option where it can fill in those areas using the new fill aware tool.

a manual crop with the marquee tool would do as you ask, i am not aware of an auto one
