This was a happy accident kind of. I shot this on the Tennessee river and they are actually on their knees. This was taken just before sunset and having a reflector shine light back onto their bodies. I first took a couple of pictures of their faces then thought about making a composite photo so I took pictures of the surrounding area to make one large photo. This one was actually better than the one with their faces. Something about obscuring faces does the trick for me.
An intriguing image!
As Jason said below, this is really interesting. Super cool idea
