Good read. How do the pros do it is my question? The camera settings are always talked about but what about the tank setup? Should the tank be back lit? Most pro shots are done without any equipment of course but how do they make he ripple effect? With a fan? Should the room be dark, maybe curtains behind you to deflect any and all external light to avoid reflections? I could never find anything on the net or youtube for some reason. Comments, suggestions.... I would love to learn and I think that would be a great addition to this sticky.
