One way to find things out is to do the dive yourself whichI did last week with Keller Laros (the Manta Man) and Jacks Dive Locker. Thedive was amazing and lived up to its reputation 100%. It was hard to believe whatI was witnessing in person; like a choreographed underwater ballet; simply magical.
Regarding WB adjustments: it was easy to WB to my lightcannon with a WB card, the problemis that there are so many other divers with so many different lights, that itbecomes impossible to get an accurate setting for the entire dive. I made surethat I entered the water after most of the divers so I could be down longerthen them and their ambient light. When the Mantas came into range from theblackness with no ambient light, the color was spot on. The ambient light inthe beginning of the dive looked greenish in color. Since I had no way to WB tothe ambient light, I can only suggest fixing the WB in post production. So forme, I had to take two routes to get the job done. The footage came out greatand I will post upon completion. Definitely the night dive of a lifetime formost divers. All I can say is the WOW factor was in full force. Another tip I can give is to keep your lightsaway from the lens as much as possible to limit backscatter from the plankton. Havingnumerous 1000lb animals dive bomb your lights with mouths wide open and turningjust inches from your face is an experience youll never forget!
