I am a beginning photographer and I want to be able to correct things in my photos if necessary. What do each of the Photoshop programs do differently? I would like to have my pictures purchasable and therefore need to have something that I can use easily to clean up scratches and blurred areas, as well as brighten colors and black and whites. I have never used Photoshop before, so my learning curve will be steep anyway, but I need to purchase a good "darkroom" program.
Photoshop Elements might suffice for your needs but it’s really up to you to decide.
If money is an issue you could also give the free Gimp a try, I guess.
