Hmm, well I am not quite sure if this belongs in the beginner's forum, because it really is a newbie question, or if it should be here, but I took a guess. Hopefully I am right.
Anyway, I recently bought a Canon S90 and Ikelite housing. Couldn't afford the strobe yet. I am planning on doing the manta ray night dive and was wondering if it's even possible to take pictures without a strobe. Has anyone tried it, and have tips on settings? I was thinking that it might be possible to due the significant amount of ambient light already in the water?
