Microcosmos: Extreme Closeups of Nature
Microcosmos is a 1996 documentary focusing on ultra-closeup photography of the natural world. Its subtitle in the original French is "Le peuple de l'herbe," which is "The grass people" in English -- the film follows the little people (okay, insects) living in the grass in a typical backyard. It's terrific. You should watch it if you like amazing photography or nature. First up, here's the trailer:
I don't speak any French, but I find this documentary completely entrancing. Here's the whole thing on YouTube:
I won't blame you if you skip ahead to 2:30, when the awesome closeup photography gets going.
And if YouTube isn't your thing, it's on BluRay.
