Re: again on color absorption

Ah, that makes more sense than the explanation for a one-time only appearance of this phenomenom in gum (on an HSL array) which was advanced on the hybridphoto site, and which has been advanced on this list from time to time, that the tonal inversion is a function of underexposure, or because the "negative" had too long a density range for the process.
To be honest, also cuprotype has a very long density range. This explains only the overall darkness, except for that overbended banana-like region ranging from pure green, yellow+black to red-orange.
My attention was drawn also from the very distinct squares in the 5-15 region.
