Subject: [pure-silver] Re: Update On 1975 Kodak Film Pack
I am always amazed how well really old film can turn out. I developed a couple
of rolls of Efke R14 that I had purchased in the 1980's. I shot at 40 ASA and
developed in Modified Divided D76 (Dignan's book) for 4 minutes in baths A & B
and wow, wow, no fog, crisp images full of detail. I have about 20 rolls left,
so I think it time to put them to good use before I expire.
Now to try a few sheets 4x5 GAF SUPERPAN which expired in 1981. Actually it
states Military Expiration Date January 1981. The box states an ASA of 250
determined by ANSI PH2.5. Probably will start at 200 ASA with the same times.
The modified D76 calls for a small amount of bromide which probably helps with
keeping fog to a low level.
Once I have tested the GAF, will try a few sheets of Kodak Super Pamchro-Press,
Type B that expired in August 1954 - ha! almost as old as me. Kodak suggests
developing in DK60a, D-19 or DK-50, and states the film is a fast Type B
panchro of moderately fine grain suitable for portraiture and other commercial
work. My old Kodak handbook suggests an ASA of 250 and develop between 6-8
minutes in the recommended developers. Not holding out any hope for this film

Subject: [pure-silver] Update On 1975 Kodak Film Pack
Recall that I scored a new old stock Kodak Tri-X 2 1/4 x 3 1/4 film pack a
couple of months ago. Expiry was Nov. 1975
Tonight I took a few shots with in in my Baby Speed Graphic and 103mm Ektar and
then "robbed" them from the pack.
I normally expose TXP (when I had it) at ASA 160 and develop for 7 min in DK-50
1:1 (I happened to have that mixed up and
ready to go). In this case, in deference to the film's age,
I shot at ASA 125 and developed for 8 min.
I almost fell over - there is no visible fogging. The unexposed edges - to the
eye at least - look like normal Tri-X. Contrast could be higher (a bit more
development time) and exposure could be just a tad deeper. Still, 40+ year old
film that produces perfectly normal negs is just a little bit shocking.
I think the remainder of the pack is likely to get exposed at ASA 100 and
developed for 10 min.
Happy to answer any further questions...
P.S. DK-50 has the reputation of reduced film fogging. It sure seemed to
work here.
