[Frameworks] Storing E-6 and D-19

[Scott Dorsey]

Kodak has a nice little booklet on the subject.

In general, fixers, stop bath, and some kinds of bleaches will last a long
time on the shelf, whereas mixed developers oxidize very quickly.  

Squirting a little canned air into the bottle can help reduce oxidation of
developer stock solutions, but I would be very surprised to hear of a 
bottle of mixed stock solution lasting a year.
