revisiting high school chemistry class

My brain is tired, yo.

I just spent a chunk of time taking notes on a bunch of different early photographic techniques: daguerreotypes, calotypes, tintypes, ambrotypes, the wet-plate colliodion process, the dry-plate gelatin emulsion, albument prints, etc. My notes are a festival of chemical terms I haven't used since high school: silver nitrate, potassium bromide, pyrogallic acid. And I'm not yet done; now that I have all this stuff noted down, I need to figure out just how I'm going to use...
