Wow. That takes a great deal of patience. I use a digital video camera, make several adjustments (e.g. lighting, outdoor, indoor, everything), and try to keep real steady. At home, I watch the videos and take screen shots of any good poses I happened to film.
I thought that's what you were doing, honestly, the shots are so good.
Once at my zoo in Cleveland, Ohio, I witnessed a rabbit get into the lion enclosure - the male lion ran after it so fast roaring and stuff and it was so scary! But the rabbit got away. He probably peed himself though from being so scared!
