If you learn the basics of angles, framing, shutter, and aperture you'll impress yourself with some shots you're able to get.

Most importantly, remember that even the best shoot a ton in order to get the ONE right picture. Not every picture is going to look good, so enjoy your time shooting, don't beat yourself up. Good luck!
