  • it is sometimes very hard to impossible to export a 16-bit tiff image that retains both all highlight and shadow information inherent in the foveon files without other damage. (Only the exposure compensation can be exactly reverted in later processing, and thus all other changes, i.e. highlight compensation and x3f fill tool, will significantly change colours)

So far this thread covers the same ground as a couple of recent ones:

I don't quite understand your sentences, but it is probably related to my one serious problem with SPP: After I raise exposure when the shot has highlight headroom, how do I set a black point? The bulk of the histogram can be shifted toward shadows, but that is not the same thing.
