edited because i didn't understand. sorry!  yeah, i can see why to test with infinites, i'm just saying you'd see a more significant change with images that duplicated, say, dramatic stage or studio lighting.

and just to say, to find your old test image, i went through the first few pages of VSS.  at least two people in the first few pages posted images that would be strongly affected by this issue.  and you posted about 2 or 3 others.
