Dear Brian,But Roger- how many photographers actually let plates soak in Mercury vapors befor using them, made custom dodge and burn tools, messed with the chemicals to get results wanted?
.
Quite a few. Mercury hypersensitization was well enough known to feature in Popular Science in 1938: the normal citation is F. Dersch and H. Durr, J. Soc. Mot. Pict. Eng. 28, 178 (1937).
Custom dodge and burn tools go back to the dawn of enlarging (and indeed to contact printing for doging), and 'messing with chemicals' goes back to Talbot an the invention of pos-neg photography.
I have most of the standard texts on photographic chemistry (Glafkides, Haist, Neblette, etc.) and I do not recall a single citation of Adams as an inventor of a process. There may be some, but I have not seen them.
Cheers,
R.
