Hello, I'm an amature photographer shooting with a fujifilm s1500. I'm helping the schools yearbook by taking photos at winter carnival, which takes place next week. I would like to help out by taking pictures at the dances. It would be dark and there would be lights as usual. What are the best settings for this? Also there is a major floor hockey tournament. What are the best settings for this. The gym is usually bright for this. Please help out and recomend settings and tips. Thanks in advance!
