Hi! I know there is someone out there who knows about my issue - you guys are all so knowledgeable around here! Right now, due to the mounds of snow, I am relegated to shooting horses in an indoor arena. Typically, indoor riding arenas are lit with fluorescent lights - which doesn't make for the ideal lighting conditions. I'm also shooting the horses in motion at the trot - so not only am I looking to catch the legs in the "proper position" but I've got to contend with the light as well. I do use an expodisc most of the time to set my WB - which usually works out great. I typically have my camera set for 5 frames per second - and I've been playing with shooting in Manual and Program mode - What I need to correct is, those 5 frames can have vastly different exposures - from way under to way over. I'm also trying to stop the motion (I normally shoot at 6400 ISO). In this photo - the cadence of the stride (catching the horse at the top of the arc with their front legs is what we shoot for) is great but of course it is over exposed. I suspect I'm going to have to go back to manual - this camera is very new to me (2 or 3 weeks I think I've had it now). Any suggestions? Thanks much!
