I'm not out to piddle in anyones pond, but I prefer to shoot in Mother nature. ...
I, too, have never photographed animals in zoos or game ranches, in part because the photo is only part of the experience. My wife and I have learned a lot about animal behavior watching the critters.
That said, a recent event around Grand Teton National Park brings another series of questions into play. What impact do wildlife photographers have on the wildlife? Grizzly 760 was one of the more photographed bears in Yellowstone/GTNP. He was exposed every year of his life to dozens, if not hundreds, of photographers (of which I was one, I'll admit) and became completely acclimated to them. Large crowds have watched him eating his way along a roadside for hours.
He was captured and moved a couple of years ago (hence the collar and his number) and returned to the Yellowstone/GTNP area. He was captured and moved again this year. This year, a couple of issues led to him being put down. So, the question is - do photographers acclimate wild animals to humans which then lead them to being shot by hunters or put down by Game and Fish? Would it be better to be taking photos on ranches?
