Thanks Randy. Basically it all came from playing with the camera. I've had the camera for a little over a year now.
Always shoot with light coming from behind you (back to the sun)
Angle is just about walking around until you find something cool. Take a shot, if you don't like it, move and try another one
Exposure: 100-200 for outside sunny day. 400 dawn/dusk with some lighting. 800 for night shots. I never use a flash, so a tripod is necessary for night shots.
Ideas = spontaneously thinking of something. I never have a plan of any shot I want. I was driving by, and saw the giant puddle (hey, I wonder if I can get a natural reflection?). Picture idea.
