I would like to have a good photo editing program. However I don't have any information to qualify one program over another. There is Paintshop Pro, Photoshop, and Picture Window Pro. The few 4x5 that are keepers I have enlarged and fixed by the lab. (BWC) The price range of the programs is confusing. A proffessional lab can make a lot of prints before I can justify Photoshop. Suggestions?
