Underwater freediving photography is really fun (and physically challenging).
You have to deal with waves, currents, your breath hold, your own buoyancy, your camera's buoyancy, adjusting camera settings using a huge clunky UW case - all at the same time. Plus it's hard to communicate with your model while out in the sea.
Not to take away anything from other kinds of photography, I can barely take photos when I'm not underwater.
