Dear Unk, Freezing B&W film is like stopping all atoms from spinning their electrons and causing a degradation of the precious emulsion. I have a brick (no pun intended) of 120 Agfa Isopan IFF from the 60's I occasionally take a roll out of the freezer, thaw it in the fridge, then allow it to come to room temperature, then use it to shoot some nostalgic subject matter. The stuff performs just exactly like it did when it when I got it, way back then. 1:100 Rodinal. I used to use IFF for commercial jobs so I bought dozens of bricks. This one is one that hid in the freezer, defying the odds, and survived until now. I have some other lovely stuff with it. Some 4x5 Super-XX, 2-1/2 x 3-1/2 (for my Hasselblad sheet film backs) Tri-X, Panatomic-X, RS Pan, and Contrast Process Ortho. Plus, Kodachrome-X, EP 120 & EHB 120 (both process E3) and some Velox F2 paper. Anyway, I personally believe that frozen B&W film will outlast you and me and still perform admiralty for our successors. BTW, I bought a boatload of Agfa 4x5 APX-100; 120 & 35mm APX-25 when it was being discontinued, and it currently lives in the freezer with the working lot in a drawer in my darkroom. I dabble in all of my old frozen friends and... they still work wonderfully. Well... not the Kodachrome-X or E3 Ektachrome. They're pretty much frozen in time. :-) Nefu Jimmy At 05:58 PM 9/10/2004, Stein wrote: > While this letter is much in the way of a testing of the waters to see >if this old computer can learn new URLs, I do have a real, on-topic, pure >silver question. > > I recently purchased as much Ilford 4 x 5 sheet film as I could stagger >out the door with on the resonable assumption that the world was coming to >an end and I wanted pictures of it happening.
