"Dr. Elie Schneour believes that the differences are not photographically significant."
Dr Schneour's name was just blurted out in the book with no reference as far as I can see as to exactly who he is. One is left to beleive that he's an Agfa employee or some sort of Agfa insider. The only hint that may be otherwise is that he is listed in the acknoledgements as "researcher/photographer"...
Instead, we find he's a guy that did a "spectrographic" analysis. That's a rather broad "type" of analysis.
Bill, could you tell us more details on Dr. Schneour's analsis? Was it with IR, FTIR, UV, or Visible light? Was it an atomic absorption spectrophotometer or an inductively coupled plasma spectrophotometer? Did he analyze for anions as well, or just cations?
By the way, I did an analysis for Total Organic Carbon and Ion Chromatography for anions for XTOL when it came out. Interested in the results of that? You can quote me in the next edition!
