I am plannimg a few outings in the near future to shoot some local minor hockey league games. The plan is to test my skills (or lack of...) with a bit of action photography. Since I will not be using a flash, I was wondering what ISO settings you would recommend. I will be using a tripod. I plan to try at ISO 400-800 and move up from there, depending on the results. Am I on the right path or should I start at a higher ISO setting? (1200 or even higher?) Any constructive advice is appreciated.
