Another alternative, (the path of least resistance), and to put an end to all this frustration, would be to hire a professional who sees the exact set up I have, and who can tell me exactly where to place lights, what Aperture and shutter speed to use in this context. At least he could tell me what to buy, and what not to buy. The problem is finding someone here on location who is not just as incompetent as myself. There's a few portrait photographers here in Fort Myers, but I have no clue if they know anything about shooting reflective bags.
As for the bags :
1. they do not move
2. I only require 12 different shots so 12 different angles.
How hard can this possibly be? At the moment I have an overload of information, with regards to the whole thing.
Then, another possibility comes to mind. Maybe, I am already getting the best possible shots for the current set up?
