“GIMP? If I wanted to use a version of Photoshop from 1999, I would just go find a copy at the Goodwill.”
Haha, even Photoshop in 1999 was easier to use than GIMP. You can do a lot with it, but the frustration from trying to do even simple things with that interface is usually enough to get you to drop the seven hundred bucks for Photoshop!
I use CorelDraw myself. Mostly the Paint program. I have never come close to being a master of it. I have tried Photoshop but find Corel easier to use thought there are more how to’s for Photoshop. They can translate over to Corel.
GIMP is free and there are many video help how to’s to look at. Many at youtube.
