What’s That Smell?

Posted on Posted in coursenotes, labnotes, paradox lost

Chemistry is frightening. Film takes a long time, a lot of chemistry and it is done in sealed rooms.
No wonder that it is a reminder of the past. No wonder that it is becoming a thing of the past.

Right now it is probably easier to find out how to setup a meth-lab than it is to setup and run a film lab.

Oh the joys of capitalism.– Skeed Remarx –“Breaking Wind”

Side Note: Tricolor Printing Filters

wavelengths of RGB that most color photographic papers respond to best are the wavelengths that are passed by Kodak Wratten filters

Tricolor Separation Printing

The original color printers, as well as the recommended printing method for Type “C” papers, used the additive filters. Three exposures were made using WR98,WR99 and WR70 (alternatively 29) filters. Kodak and Fuji have since improved color separation between the Type C (RA4) color layers. Additive printing was essential to take out the ‘pumpkin’ yellows. The tricolor method kept the yellows clearer.

use the WR70 as the base exposure. The Red layer of the paper is the speed determining layer.
