I am trying very unsuccessfully to take shots inside a well lit dog arena with my D7100 and would like some suggestions on settings. I do not want to use a flash so the dogs will not be scared by the camera. My exposures haven't been too bad but any movement by dog or trainer is nothing but a complete blurry mess. Everything I have tried hasn't worked, and the results are so bad, there is no need to go over my failures. Just a good place to start might help, so I'll try to stay open to most suggestions. I know it will still take weeks, meeting once a week before I might get lucky enough to find a setting that works. The cell phones are looking so much better than anything coming out of my Nikon (embraissing for Nikon, not me) that I will no post online to share a single shot. Times like this I'm really sorry I bother with a camera that has endless settings that if everything is not tweaked just right you end up with complete failure.
