Okay, so another strange idea. I wanna make a portrait of someone in water, with the subject maybe around 12 inches below the surface. The camera over the water. If I choose to use strobes to light the whole thing up, what should I think of? Polarizing filters? How much of the light will bounce right back? Water has a pretty high albedo last time I checked. Could I put a small flash unit in quadruple freezer bags and go nuts with electrical tape on it and trigger via radio trigger, it a few inches below the water? I plan to use a handheld flash meter in reflected mode since it won't work under water, but how do I now I get a reading from the subject and not just the surface reflection? Should I just bracket away? Tips welcome..
