Micki, if you're under purely actinic lighting, it will be dark. If you're under daylight (CFL, MH, LED), it's fine. As I told my wife, it's a $99 camera for use underwater, and it's going to give you about $200 quality for the price. I have a 20 minute vid that I'm going to put up on YouTube that Kenn has seen that looks pretty good.
