:) I was just too late to reach you this chat session! Anyhow. I've taken some pictures in aquariums, most of them NO good, - but some of them at least good enough to be used to illustrate what not to and what to do. *lol* Circumstances around these pictures: They are taken 4 years ago, with the first generation Casio digital cameras. The technology has come a LONG way since then. Also Monterey aquarium is pretty professionally set up, - meaning that several of the tanks seem to be set up for photography. They had back lights. Like this one. What I did (in addition to take a LOT of pictures that are rubbish) - was of course NO flash light. :) The light is the crucial thing here and in the next picture, - the light source was a bit different....
