So my friend gives me this box. (no, not spam).

Hi Laura, Thanks for doing research for me. What I meant by "how to develop the film" wasn't to say I am going to ship it out. Afterall, this is a darkroom newsgroup I am curious as to what *chemicals* and times to use to develop such a film. Based on my experience with found film, I'm going to suggest HC-110 because of its good antifoggant and otherwise generic nature. If it were mine, I'd use Dilution H (half of Dilution B, 1:63 from USA syrup or 1:15 from stock solution) for the equivalent of ten minutes at 68 F -- though I find most folks seem to develop longer than I do (which is probably an artifact of how I start and stop my timer); in any case, I'd go for about twice the normal Dilution B time for current Tri-X, which I recall as being around 5 minutes. Doubling that time in half the developer strength will give a slight push, and ought to compensate for latent image deterioration in a minimum of about 30 years (since Kodak quit selling that film in metal cans) and more likely up to about 50 years ("Super Speed Safety Film" puts it before Royal-X, which was IIRC introduced in the early 1960s). Tri-X is known for getting foggy over time, and you'll probably just have to print through some fog; the push will help compensate for the loss of contrast due to the age fog (that HC-110 can't completely suppress). Concentration shouldn't be a problem, but when diluting HC-110, make sure each 135-36 film equivalent gets at least 3 ml of concentrate. For your 20 exposure roll in a 35 mm stainless tank, you could use Dilution G if you choose and not come up short; that dilution would require around 20 minutes at 68 F. BTW, the more you dilute HC-110, the more grain you're get, but also the more acutance. -- I may be a scwewy wabbit, but I'm not going to Alcatwaz! -- E. J.

So I get my HC-110 solution setup and so I go dark and pop the 35mm
cannister and guess what.. NO FILM IN IT. game over, man, game over. so sad. Guess the guy that shotthe film had a tendency to keep the cannisters and containers. |

Which is why I always load the film into the tank before mixing anything -- why mix up chemicals when some snag (and yours is only one of many possible ones) will keep you from developing? -- I may be a scwewy wabbit, but I'm not going to Alcatwaz! -- E.

Yeah hindsight, et al..Its a good point moving forward though..I
suppose you could say I was preparing everything in advance for an eventuality that never occurred Thanks for the tips...Too bad I didn't score this time... Sigh.

Sigh. Which is why I always load the film into the tank before mixing anything -- why mix up chemicals when some snag (and yours is only one of many possible ones) will keep you from developing? Of course, the other side of loading the film first is that if you run out of time and don't get it processed right away, there's a hazard of forgetting what was in the tank. So, I also stick a piece of masking tape on the tank and write the film type and EI rating on the tape, so if it takes me a week or more to get around to processing, I won't process old TX thinking it was TMY, or four rolls of 35 mm thinking it was two rolls of 120 in the same tank (the latter important if using very dilute developers, as I often do). -- I may be a scwewy wabbit, but I'm not going to Alcatwaz! -- E.

Gee, that's the way I remember Tri-X from the early 1960's. Metal can,
screw top. The film casette end caps will pop off and it is reusable. From long before they changed to crimped end plates you have to open with pliers. Probably find a thick emulsion too. Great film. Develop as for Tri-X, but you might want to compensate for expected fog level being higher. M. T. Sandford |
