Is this my imagination? I was discussing cool alternative processes with my son and mentioned a French process I couldn't remember the name of. I think it was called Frisson Process, but am not sure. I >>believe<< the fashion photographer, Sarah Moon, did a series of prints back in the '70's-'80's with the Frisson Process, but, again, not 100% on this. As I recall it was done by only one company in France, passed from father to sons, etc. There is absolutely NOTHING on google about this, so I'm not certain if I just made the whole thing up. Hmmm.
