  Here's a question for all you people out there, one that I'm feeling too
lazy to go out and look up the answer to:

  Am I correct in a vague memory I seem to have, that the (Earth's) moon is
supposedly a near-ideal Lambertian reflector?

  I was recently putting a crescent moon into one of my landscape images, and
found that I had to use a gamma of around 16 on the lunar surface, in order 
to get the terminator on the crescent moon to look right.

  There's somthing fishy here, methinks.
