When teaching jewelry making years ago, my goal was to have students get the basics down pat. That was and is the building point. Agreed, don't get too caught up in software! And, know the basics, first starting with your camera! I have a relatively new camera and make mistakes with it from not paying attention to little details. I would try to keep the manual handy and learn everything you can about how the camera reacts in different modes, etc. If you then get a wonderfully exposed shot or a blown out ruined one, you will have an idea "why" and be able to back up and do it better the next time. As I see it, learning how exposture works and learning to nicely frame the image in the view are two good places to start. I am still learning my newer camera and trying to get a better grip on the solid basics of good photography. Best wishes.
