Roman,
Do you know Dave? If not, let me introduce you to him at the next MWDC meeting he's at. He's pretty much the photo guru in our club.
I know he's got a setup with a camera with two strobes [well, and a nikonos V mounted on the top of the other camera housing
]. Both of those strobes have SL4s [Don't remember who makes those. UK or Princeton Tec; UK I think] mounted on them for spotting.
I've used my light for spotting when I'm taking shots at night. It works out pretty well, but I do remember to point the light away once the camera has locked on.
I've tried taking shots with the light as the source of light, and it just doesn't work right [I'd have to dig the original off a CD, but here's a crop out of my index I made before I archived].
Someday I'll have an HID canister light, and I'll give it another try
BTW: I had one of those Atitude lights. I truely loved it, both diving and it was a great light for getting around the bunkhouse without pissing off the sleeping dive buddies! Unfortunately it flooded
