    no, I have used a PDF found at the GEH website, illustrating the "Greenlaw process"; inside there are instructions for 3 possible kinds of calotypes, one of which is dry

    here's the link:

    Interesting website; I didn't know about it. But I suggest you might have a look at Alan Greene's book which might be particularly profitable for you as you already gathered some practical experience. Greene's instructions are all meticulous; quite labour-intensive, but they seem quite extensive and aim for completeness, and thus might be helpful.

    His dry-process involves, for instance, prior waxing and three cleaning baths of destilled water to complete the sensitizing (the silver sunbeam advises, if I recall correctly, only two). He also gives timings: 20 to 40 seconds in full sunlight at f4, everything else runs into minutes.

    Personally I really feel appealed by some of the picture reproductions in his book, other than on this pdf which only shows nondistinct text negatives.
