I'll also note that I tend to use the shade of gray on the mask (one mask
for odd zones and another for even zones at the minimum) against the shade
of the shadow when I really get going with the testing and this means that
there has to be some light in the room to get that gray on the mask rather
than the black when the lights are fully masked off. Bob May
