Here's the contents page for DCG and other materials. I used the method of carbon printing (chap 2.1b) to show it was possible to use DCG as a resist material. We recorded a thin hologram on DCG with depth < 1u, and then transferred the image to a piece of plastic by casting. We poured Norland onto the DCG, and laid a plastic film on the Norland. After curing the Norland, we peeled it off and showed the image on the plastic film. Processing was simply a warm water bath.

Amazing! Using it as a resist seem to be the classic approach to DCG. By the way, I am pretty sure the ferric or diazo gelatin systems could be used for this as well.
In the context of DCG I always wandered how Curran/Shanoff got to the alcohol dehydration thing. I never found anything alike mentioned before in the photographic litterature.
