I am trying to hone my picture taking skills. I am using a Toshiba 4.0 MP point & shoot. This has most of the standard options like macro, white balances, shutter speed, etc. Is there a genral setup used for a starting point to take pictures through the tank? Then adjust from there. Any help on this would be great. I would like to be able to get some decent shoots with this camera then once I hone my skills, talk the Boss (fiance) into maybe an SLR. TIA
