If your "field", i.e. the majority of your displacement map, is white, than anything less than white, including "neutral gray" looks like a negative displacement.
I would accept the notion that you think of black as an indentation, when used against a non-black field. But it is very confusing to people if you tell them that gray causes no displacement. It is really important that people understand this. It is why you get bloat on a figure when you plug a gray-neutral displacement map into a Poser figure. It's fine to say you intend the black area to be a negative displacement, or and indentation of the field, but to actually say that black is or causes a negative displacement is incorrect, and many Poser users get very confused by the strange behavior they end up with.
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)
