The question is: Does it use 255-bm or just -bm? And would that make any
difference?
It wouldn't change anything. The local differences that are used to
compute the surface normal would be exactly the same.
Dude, follow the math! Read the

what if you color invert the one you use as the bump map?
if you use same layer, then duplicate, color invert, and use the

What he is suggesting is to invert the color value, so white
becomes black, and black areas become white, so that the bumpmap
will take a different height field to achieve the "inverse" effect..
I have tried it before but do not quite like the result..
IMHO, the PS Lighting effects did it

Nope, that is not it.. Unfortunately, the Invert Bumpmap
option works just like the Azimuth, it changes the direction
of light 180 degrees, e.g. from NE to SW. That doesn't
do much to create the "carved in" effect.
??? what is carved in supposed to mean, then?

Hi All,
I have been using the bumpmap plugin quite a lot lately.
It produces some very good embossy effects and I am very happy with the
results, thanks to the effort of the programmer.
