I just downloaded and installed GIMP from http://www.gimp.org. Before I did I looked a few review sites and the consensus was: “If Photoshop is a 10, this one goes to 11″. Nice reference to Spinal Tap.
This program can do everything that Photoshop can, it can open PSD files as well as all the others. The only thing is, you’ll have to learn a new program…but it’s FREE!
I recommend GIMP especially if you can’t shell out the $700 for Photoshop. I’ve already uninstalled my trial version of Photoshop…bbesides, learning something new is always good!
