Hey guys. I'm goinge to be getting a nikon 35mm soon, but I was wondering if anyone had some tips for taking pics of my tank/corals with my digital camera. It is an olympus stylus 740 if that helps. I have an underwater macro setting, but I just cant seem to get the color of my corals. With the flash, well you can imagine what that looks like. W/O flash, the pics turn out blue. I have tried taking pics under my T5's only and with halides. Any ideas?
