Horses from this angle look like a completely different kind of animal. I'm not sure which kind of animal that is, but it's a hilariously cute and silly one.
I wonder if horses see each other this way, and this is what they think they look like. The trick to getting a horse photo from this angle seems to be to stand directly behind the horse's eye, and point the camera towards the horse's mouth.
These photos make it look like the horse's snout is just a tiny little nub on the end of a giant, plump head. If I had horses, all I'd be doing all day long is taking photos of them like this.
