Good thought, Bob, and very valid. Unfortunately, the high-Kelvin theater
lights weren't what I had to work with (I've actually been there). In this
case, there wasn't much "clip" for black, and the sampling-down wasn't
enough. But I *do* know what you're talking about, and thanks for bringing
it to my attention. It's another tool in the box. :-)
