I'm not a videographer, but in answer to the person who asked about using his wife's still shots in the video -- As a video ENJOYER, I love people who do that. Use the video to give the overall impression of the site, and the motion and progress of the dive, and interpose good still photos to bring in the true colors, and to record fine detail. I have seen some videos done by pros where they used lights and macro, but you can never really be still, and the smaller the subject, the more distracting and annoying the motion is to the viewer.
