I'm not sure if I have a stable list of favourites, except for a few names, but here's what floats my boat these days, in alpha order:
Bernd and Hilla Becher
Chris Marker (well, he's not just a photographer, but he's also that)
Andreï Tarkovsky (yep, filmmaker, but his book of Polaroids is amazing)
Using film since before it was hip.
"One of the most singular characters of the hyposulphites, is the property their solutions possess of dissolving muriate of silver and retaining it in considerable quantity in permanent solution" — Sir John Frederick William Herschel, "On the Hyposulphurous Acid and its Compounds." The Edinburgh Philosophical Journal, Vol. 1 (8 Jan. 1819): 8-29. p. 11
