Yes, I absolutely see why you went with diazo sensitization. It is quite remarkable honestly! By the way, do my emulsion #'s indicate a specific date, 1996?

I think the stain must be a function of (a) mainly, as it is only in the whites of the print, and not in the area outside where the negative was. I'll try to scan it and post it for the sake of showing this. I did not wash the DT paper other than a 10' soak before sandwiching.

Thanks much for the clearing instructions.

Greg, from what little I've read so far, it was intended for high resolution half-tone negatives as well as cont. tone.

Does the lab manual cover negative sensitometery? I guess time will tell!
