    I just processed the first film from my "new" Pentax 645n. Beautiful, consistent negs on Arista 100 BW. Funny thing, the 1 to 1 D-76 poured out with a pale, blue-green, or cyan tint! I've never seen this before with Kodak or Kentmere film. The film itself is untinted, looks good.

    Development for 9 minutes at 69F, 30 sec initial agitation, then 5 sec every 30 sec. D-76 one shot, 1 to 1.

    Anyone else have a similar tale?

    Acutance dyes, should be totally harmless. I assume you did no pre-soak?

    I process everything in Pyro with no pre-soak and find that just about every new film these days turns the developer a different color. Some are brown, some are red, and some as you have experienced are blue green. As I understand it, it doesn't mean that anything was done wrong. I believe that if you pre-soak before developing, most of that color comes out with the soak water instead of the developer.

    Thanks, folks. The film has a faint cyan tint which should have no effect on printing.

    I have the same tint in my XTOL from souping Arista EDU Ultra. The developer is perfectly fine. I been told it's anti-halation dye left from my film.
