PE,
Can you give some examples of panchromatic dyes ?
I actualy tried,with one emulsion,adding both SDA3057(at 150mg/M Ag) and SDE3008(at 50mg/M Ag). It looked pritty good, as judged by a shot of the Kodak color chart. I went back to splitting batches though. Just to be on the safe side. Also, when using a split beam camera, I can actualy use a differntly sensitized emulsion behinde each of the color filters. I like that for several reasons.
