Yes, that's right. A friend has asked me to go "spot-lighting" with him, to photography some of the fauna in a local stream. Not too hard during the day, but most of them don't come out until night.
I'll be shooting with my D90, 18-200mm f/3.5-5.6 and SB800 flash. I'll also throw my polarizer on to try and cut down on the surface reflections. I do have a 50mm f/1.8 too, but no polarizer.
The current plan is pre-light as much as possible; probably a hand full of torches, as we're a long way from mains power (though I may have access to some 300w tv lights which have battery packs). I expect I'm going to have to find the right angle relative to the light, not so far off center that I lose light, and not too close so I get reflections.
Any other suggestions?
