thanks for the reality check. looks like I DO have to coin up (which i will). underwater is definitely a different game.
as for artificial lighting. that is out of the question. i am not interested in taking closeup. most of my targets will be 20'+ away. must rely on natural lighting.
i need a camera that is designed to produce clear crisp video in low lighting. (a compact camera will be a bonus)
please do keep those 1st hand experiences/recommendation coming. which camera and hopefully with a youtube video example? thanks.
How about this : GoPro Video Lighting System ?
I used it to 56 m in Truk Lagoon, inside and outside wrecks. Performed beautifully.
