Slightly off topic (or maybe not so much)... I've got a Canon S50 (with Canon housing) that I will be bringing on my trip in October. I'm still struggling a bit to take good pics... granted, the only test run I've given it so far is to fill up the bathtub, throw a few rocks in and stick my hands under the water to see what I get, so they're not nearly as spectacular as your shot, for sure, but did prove the casing didn't leak if nothing else. Anywho... my question is, what's the best setting to leave the camera on for underwater shots? So far I've just been leaving it on auto with very little success... tend to get a lot of blurry shots. Also, does your camera give you the option to turn it on/off while underwater? Mine seems to have the option of 'on' and 'on with viewscreen'. If you leave the viewscreen on the whole time you're underwater, how long does your battery normally last for? Thanks.
