I am just getting the hang of shooting on apperature priority...most shots at f3.5 -4 at a 60th. The shutter speed did not vary yesterday (in 10' of water, moderate sun) and the fish pics were out of focus. I have been advised by an expert NOT to change the settings, but I'll never be able to get good pics of moving fish if I don't go to shutter priority! Any suggestions, anyone? THANKS!
