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. Both those explanations were easily refuted; this one has some merit in your case, especially if it happens every time. Mine, as I said, happened only once in many printings of the same HSL array with the same light source and correct exposure time, so this explanation wouldn't work for what happened in my case any better than the other ones did.
