Aloha Ayse,
I switched to manual white balance several years ago to a marked improvement in color. I have attached a retractable clip to my tank band on my BCD with a 5"X7" white plastic slate attached. Once I am ready to shoot, I reach back, pull the slate forward, hold it about 1 foot in front of the lens and manually white balance. I verify the results in my color monitor or viewfinder, then let go of the slate and it slides back to the tank band. Previously I had the slate attached to the housing, and it was akward to unclip and use then try to reclip in a timely fashion.
I find at night, I only need to white balance 2-3 times for a dive, and then only if I change from 1 to 2 video lights, or from wide angle to macro. I use halogen lights that can be a little red with auto white balance, but are perfect with the adjusted, manual white balance.
During the day, I need to manually set the white balance every time lighting conditions change. I am unable to set sometimes below 50', in which case I use the alternate settings on my Sony VX-1000 and choose the one that looks the best (most often the artificial light icon).
I have found that the automatic white balance is much less accurate that the manual white balance setting. I use the manual white balance and a UR-Pro filter together. This allows me to shoot with the filter in as little as 1 foot of water, without having the overpowering red come through. I have had success in Adobe Premiere adjusting the colors in post production, but I would much rather capture good color than try to have the computer make good color.
Good luck,
