The lighting in the gym was really really good - I was looking up bball shooting before I went and I heard lots of horror stories. The metal halide lamps were 40' up, but there were lots of em.
some of these are at ISO 800, some at 1600. Since this was the first time, I was playing around a bit. Even at ISO 800 I could stop the action at 1/320th - I had the camera on shutterspeed priority and had a period of 1/320th and 1/400th. I didn't want to push the t1i further than ISO 1600 - I think thats the max of its actual ISO and I was getting decent shutterspeeds.
I was shooting automatic, AI servo. I did spend some time in each of the corners, and some time at both sides of half court, to try and judge which was best.
It was a good learning experience I think, one I'm likely to repeat a couple times for sure.
