Re: [Leica] Preserving prints and transparancies

Mike-
Totally fixed and archively washed negative should be kept in a cool DRY
place. I printed one I did over twenty years ago in a darkroom session
yesterday and it was completely unchanged as far as I could tell. Fungus and
heat are the most common dangers to negatives; I use the high density poly
sleeves and like I said, have had no trouble.
Toning supposedly helps by 'plating' the silver grains with an even more
stable metal salt compound- Gold toning is admittedly the best, but the
reddish color bothers some.
The real key is to fix archively with two baths, and to wash thorughly, and
use a test for residual fixer (a dilute solution of potassium permanganate
which is purple, will turn orange with the slightlest trace of fixer) and
store in acid free boxes.
