I don't own an SS 120, but read this post with interest. This specific behavior has also been noted and griped about on the LS-8000 -- ie., histograms that fall off abruptly, on the low end, at a value well above zero. On my Nikon, using NikonScan, this cutoff appears at a count of around 20-30 (out of 255.) The "fix" for this problem (in NikonScan) is screwy, and probably not applicable or transferable to the SS 120, is my guess. Frankly, this (mis)behavior doesn't concern me nearly as much as the opposite problem (clipping.) rafe b. - Turn off HTML mail features. Keep quoted material short.
