As much as I love Photoshop, its an expensive program, however, there are lots on online photo editing tools available for FREE...here are 28 of them. Each tool offers a variety of tools to edit, distort, and have fun with. I used "Picnik" to do some color correction on a photo of Alex (my son) sneaking up on an unsuspecting sea urchin (no worries, no sea urchins were harmed while filming) Jeffrey Eckhardt (14) was the photographer...nice shot.
Photoshop Express (from Photoshop)and FotoFlexer are online tools that weren't mentioned in the list (but should have been). If you use these tools for anything you can at least crop or reduce the photos before emailing your friends a super enlargement of their face you took with your 11 Megapixel camera ;). Check them out and have fun!
