    Don, you're right about a water bath not stopping development immediately. However, there are two reasons I use a water bath as a normal part of processing.

    First, with the acid stop there is more of a possibility of pin holes in a soft emulsion. The Efke films I use tend to get holes in an acid stop, as they are noted to be prone to scratching and holes in general, due to their soft emulsion layer.

    Second, if your "normal" procedure is based on times and temperatures which have been derived with a water bath as part of the process, it isn't a problem. Consistency is more important for me in this respect, so I use water. tim

    When pyrocat is used, does the dark brown color of the solution mean it's exhausted?

    Yes, Pyrocat when freshly mixed should have a pale yellow color. Once it is exhausted it is brown.

    Thanks! I developed 4 8x10 sheets and it looks weird next to a D76 negative of the same scene. Haven't had a chance to print them yet though.

    As you say, if you compare the negatives to a non stained negative the stain is pretty obvious. If you are planning on using the Pyrocat negs for your zias, give them at least 30% more exposure.
    Good luck and let us see the results...

    Ziatypes, and alternative printing out process. Pt/pd prints are developing out prints.
