??? what is carved in supposed to mean, then? the impression of height
in bumpmap is only achieved by the gradient ("the direction of light").

invert bumpmap means what it says: invert the mode of operation.

yes. but that's what invert means. change the gradient so one has the
impression of a sunken (or raised, depending on the bumpmap) "crater".

a layer mode is nice of course, but invert still does the right
thing. no need for experiments.
