Tri x sell by 1978! : LUSENET : B&W Photo - Film & Processing : One Thread

Hi there,

In my quest for Apx25, I managed to acquire some frozen rolls of tri-x and apx 25 dated 1978 and 1980 from a customer at work. I know that tri x's emulsion was very different from todays, but what year did it change? and does anybody have some dev times in rodinal and also will the emulsion be intact?!!

Hmmmmm, wasn't the Agfa film called "Agfapan 25" back then? APX is a newer version.

I had some film in storage for some time, had to be close to 10 years, (time does fly). I shop some, developed, etc. and it appeared to be fine, however, several weeks later the emulsion began to flake off. Important lesson learned. 10 years is too long for my taste. I have had some frozen for several years without problems, at least not so far.

Yeah you're right, I just looked at it again, Agfapan 25 Professional... and it's from 1976, I was only four years old! The Tri x is 1978 and 1980.

There are dev times of course inside the box, but didn't Rodinal change its formula?

Rodinal did change, but do not aske me when.

Ann, the film rolls you had problems with, was that a developed roll or a unused roll? I talked to a guy who has Adox films stored in his freezer for 30 years, and they still are good.

The limiting factor for freezing film does not seem the physical or chemical consistency of the emulsion itself, but the exposure to natural radiation over the years which accumulates. It might create fog.

Recently a friend gave me a roll of 35mm Tri-X exposed 1971 needing development. It had been found in a cupboard. The developer I used was TMAX, gave it a boost (50%) and voila. What a film, high fogging yes, grainy yes, but the images were there and printable, you could even still make out the Tri-X signature tonal values.
