Hi Dave,
Here are a couple of ideas/tips. Both shot with Nikon 16mm fisheye and film (by the way, d2x is on the way in the next few months).
The first one, from Fiji is in ambient light, while the second photo uses two flashes (IKE 200s) at 1/8 power not to overexpose the jacks. Shutter speeds are 1/125th of a sec and the aperture is around f8 or so, if I remember correctly.
I strongly suggest to always shoot in manual so you do the thinking, not the camera.
Instead of getting really fancy and using ND filters - something to remember with this kind of photography is to always position the sun on your back, if possible, so you don't blow out the skey/water/etc. Using Velvia or the equivalent setting in your digital camera generates the rich colors.
In both of these shots, the water was too deep to stand in. So... to stablize myself and my ancient film camera and strobes, I used a really hi-tech piece of gear. Are you ready? Sea noodles!
That's right. The kind sold at pharmacies and supermarkets for young children to use in the pool and ocean. Two of those provide plenty of buoyancy to balance your camera and stablize yourself. Just put them across your armpits and viola. They cost about US$2 apiece (just watch Nikon put their logo on something similar and sell them for $50 a pop).
For the Fiji shot, I used my sea sausage (surface signaling device) partially inflated. With fins and a snorkel, I swam around in a little cove in beautiful Yanuca Island and shot away - and got many many keepers.
Spit also works great to minimize water droplets - which in my opinion are no major sin if kept to a minimum - adds a sense of being there - having drops on your mask as you surface...
Good luck,
Michael
