I thought things like staged photos and events were pretty common knowledge. I mean, James Audubon hired hunters to collect specimens for him so he could make all of those beautiful bird paintings and Disney running lemmings off the cliff seems to be the event everyone always brings up. It can often be hard to get good shots (if sometimes impossible), even with lenses that can focus farther, higher definition cameras, better imaging technology, motion activated cameras, those fancy little snake cameras, etc. Documentaries often use a lot of really cool tricks, such as filming insect activities in studios with special artificial nests or taking two or three different reels of completely different animals of the same species hunting and splicing them together. The way I see it is nature is a fickle thing and even when you're in the thick of it, it's easy to miss what's going on. The filmmakers are doing their best to tell fact based stories and if that involves using a little trickery, I'm okay with that. I think the only issue I have is when wildlife photographers use bait to lure animals into a shot. I'm very anti-feeding wildlife (I'm even morally against birdfeeders and bird baths, believe it or not) and I don't think that's okay in the slightest.
