Our approach to UW Photography
Hardware
Just camera (for now it's SONY DSC-P100) with underwater housing (Marine Pack MPK-PHB) and two UW lights.
Software
Any software capable to adjust "levels" or "autolevel" will do. The good choice is Paint.net . It's very robust and absolutely free. You can see below what you can do just applying "autolevel" operation to your camera image
