It is not just a matter of learning Photoshop. The photo must look good to begin with. I learn so much about composing the shot, tips and tricks, and how to use m camera online. The Kodak site is very good. And googling finds all of the education an amateur like me can ever use.
I used to be the "go-to" gal at work when it came to kids' birthday party photos. Supposedly intelligent parents shoot the whole party without ever looking at the camera screen. I could pull out a lot of details in a nearly black photo of the kid that was shot facing toward the window, leaving nothing much but a shot of the white window light.
Can't really criticize them though, because a room full of 5 year olds takes up much more of the adults' attention than they can spare for snapping photos.
