I am an absolute beginner with editing software. I have never edited an image with any program. I've always tried to get it right in the camera. Fine art photos that I've framed and hung at home have not been altered. What is the easiest editing software or program for me? I plan to make only simple enhancements...nothing fancy. I mainly shoot fine art stuff. I've got a Canon 40D with two lenses: Canon 10-20mm and Tamron 90mm Macro. Thanks in advance for any suggestions!
