Yeah, I kinda keyed in on that last week and was playing with my waterproof point and shoot, my DSLR let's me dial in a custom k level if I want but I havent had the time to set it up and play in a while...
This is exactly what most people run into. Most point and shoots don't correct for the white balance properly under the blue actinic lighting...mainly because the photo-sensors in the camera aren't picking up "white light" under the actinic bulbs. The Kelvin temp of most reef tanks is going to be outside of the "expected range" of those cameras. You can correct the hue/saturation post-exposure with photoshop...but even then you are limited unless your point-and-shoot takes pictures in RAW format.
If you have a DSLR that allows custom temperature setting, then it just takes a few minutes of fiddling with the settings to get things dialed in.
I'm sure there are others here that have more experience with photography...especially when shooting reefs, but I'd be willing to help out with some pointers if anybody has some burning questions on how to set up their DSLR's white balance for tank photography. Let me know and I'll be more than willing to do so at the meeting if the host/mods are cool with that. I can also bring my camera, tripod, and remote flash (nikon mount) for anybody that wants to just play around a bit. FWIW...a flash placed off camera can really help level out the blue hues too, but it does add another variable to setting your white balance correctly, and of course it's only a convenient solution if you have a DSLR.
