[Frameworks] shooting and hand processing expired film

[Scott Dorsey]

Shoot a test, process a test.  Just take fifty feet or so and run it and
see what it's like.  You may need to open an extra stop or so.

When you develop the test, look at the edges of the film where it has not
been exposed.  Compare with some other processed negative... it should be
clear and not grey.

If it is grey and fogged, add some benzotriaole to your developer.  This
will reduce the effective film speed but it will also reduce the fog.
Photographer's Formulary has the stuff in stock.

Vinegar syndrome is death.... it is a very distinctive odor and not like
a musty smell.  The acidic gas produced will cause other film to go vinegar
if it's stored nearby.  I have never seen vinegar syndrome on old unexposed
negative but I suppose it's possible.
