"80%" - yea sometimes. Other times it should be 200%.

It depends on whether you're simulating a camera exposure set for shade or for sunlight. If you are "photographing" somebody under an umbrella, the exposure will at least triple, possibly more. Depends on the ratio of ambient to direct light.

To produce the same effect in Poser, which has no "exposure" dial, we adjust the light intensities instead.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
