Just curious if anyone else has had this issue or wishes to postulate a guess as to what happened...
I recently found a couple of 120 rolls of Tech Pan in the bottom of my freezer; I'd guess they're about 20 - 25 years old and have been stored in some sort of container in my freezer since bought new. Since I, also recently, discovered a web page by Jay D describing semi-stand development of Tech Pan with 510-Pyro I decided to shoot a roll. Just shot and developed it this morning and about 1/3 of the front part of the roll contains no images. The seventh frame is about 2/3 there with all remaining just fine.
So, it appears that the film more toward the center of the spool was OK with the front part not so good--no image recorded! I thought frozen film--especially slow speed film--would last darn near forever in a freezer. Not true? Or, perhaps Tech Pan being what it is was somehow affected by light? Very curious about all this because I fairly recently bought 50 rolls (35mm) of EFKE 25 thinking it would last me for my remaining years, if stored properly.
Thanks for any insight provided.
