I becamse a member of the photoshop website and have played a little with their photoshop express, but have not done much. I am worried I won't have time to edit my photos, but sure would like to so that they are nicer.
I use Photo Impact, but do not edit photos. I don't have the time. I'd rather take a few classes and improve my photography. ;)
I have read though that it makes a huge difference even in great photos. Plus the coloring can be off so you can make pics look more natural. But like you, time is the big thing.
