Going to try some shots at my daughter's volleyball game tonight and I'm not sure which would be the best priority setting for my 20D - Aperture or Shutter. I've played around with both Tv and Av settings, but not experienced enough to know which is better light-wise for an average indoor gym.
I realize I can try both settings tonight and use the more appropriate one next time, but I am trying to maximize the amount of time I get to watch as well as learn to take decent pictures.
