Well I was kind of hoping for some math wizardy to apply to a Poser light. I prefer using Poser lights rather than emitter objects, which to me are a pain. I've only done one successful image of late that had a light emitter in it. Generally I don't like how light emitters reflect in the figure's eyes.
