Hey Jim, since you are experimenting, why don't you place a flash camera and an IR camera in the same location. Set you IR to video and you flash camera to burst mode and maybe you could video the effects of white flash on the deer and see how they react. I have been gonna do this for some time but since I had to pull my camera I never got around to it. Maybe somebody on here has done such an experiment but I haven't seen it. Since you produce some excellent pics anyway, I think you may get some really great footage. I may try and do that myself after the wheat harvest is over here.
