I think what you are seeing is the effect of light bouncing off a
black surface. Depending on how you are rendering it, you can change
Lighting values to effect the true blackness of the render. If you
rotate the image, does the black look different and different
orientations. If so, this is definitely your problem. Are you trying
to use black on a black background (trying to make it non-existent?)
If so, you may be better off to invalidate the data in the black
range instead.

Hello,
I use OpenDX to visualize CT data in greyscale. My problem is, that
black color in the colormap editor does not show up black but
(light) grey in the image, e.g. the black-to-white distribution is
reduced to gray-to-white. Any idea what causes this behaviour?
Thanks!
Christoph
