Thanks PE,
If anyone is interested in a tested and working red sensitizer, SDA 3057 is $600/gram + convenience fee+tax+shiping. We did a 3 man order several months ago. I am the only guy who has run out again.. Anyone interested in a red sensitive dye that works, send me a private message. I believe that PE will confirm that this stuff works well. He is the one who put me onto it. Otherwise, I would not have a red sensitive emulsion at all.
