Going through some old stuff this evening. Here's a shot from Samoa. It's the reef guys were surfing over and I was swimming over.
Wow... I'd love to get a shot like that... what settings did you use?... do you remember? What's your ISO? I've tried a shot like that with ISO 400, and 15 seconds is never enough, which I think is the max time length for my camera... plus it gets grainy.
