Heartography is Nikon's solution to knowing which moments you're going to want to remember with a photo. It's also the first camera rig that's been subject to animal testing, namely, Grizzler, a Border Collie/photographer. Nikon strapped a photographic device onto Grizzler that took a photo whenever his heart rate jumped, successfully capturing emotion-stirring images on film. Watch the video compilation below, in which Grizzler inexplicably has the voice of an unbelievably patronizing human being.
