Hi, I’m the shooter David talks about – thanks to everybody for their comments.

I shoot Sharks and my primary aim is to capture fast action with a minimum of motion blur, hence the 720/50 overcranked to 60, 180 shutter. I also under-expose by 1/2 as in my experience, all camcorders over-expose when UW, and the exposure is spot on.

This is however not an issue of exposure.
I operate on auto iris (can’t be fiddling around) and the aperture sits comfortably at around 4. I get grain on sunny and cloudy days and whether I aim against the surface or against the bottom, meaning regardless of available light.

The grain appears in large uniformly colored areas of blue water as opposed to images where there’s a lot of different elements. One friend suggested that this may be the result of variable rate compression when writing to the SS card.

Went diving yesterday with a PP with detail set at -20, crisp at +50: no notable improvement!

Any UW shooters who could give me some additional tips?
