I'd try a snip piggybacked onto another roll developed in HC-110 dilution B and see what kind of fog you have before even loading any of it into the camera and shooting. Could save yourself some trouble. Just unspool the roll and take a little snip off the end, then respool it.
IME, expired film isn't that useful unless you get it in large quantities. What good are two or three rolls of something if you have to shoot at least one of them just to get a handle on the film?
My PLI shows to develope it for 12 mins in ID-11 1+1 for G0.55 and 18 mins for G0.70. You could try half speed (200) and these times or even at 100. One thing I would do is develope at temps below 65f and adjust time to help reduce fog.
Add a little benzotriazole to the developer to decrease the fog. Use times suggested by Steven and develop the first roll. YOu can make any necessary adjustments from there.
I have a 5 roll box of 120 HP4 sitting in front of me, expired 5-79. On the box it recommends:
ASA 400, 7 min. in ID-11
ASA 650, 5 min. in Microphen
ASA 200, 8.5 min. in Perceptol
All at 68 F. Agitation for 10 seconds every minute.
Of course that is for fresh film but possibly will give you a starting point.
The price tag is still on the box. A whopping $2.00!:laugh:
Thanks to everyone for making suggestions on how to do this.
I ended up trying hpulley's suggestion.
The results was pretty much as I expected.
But I don't mind that. As I said, that was what I expected!
One funny thing though, is that it seems the emulsion is sort of peeling off the film!?!
I guess it has been stored in a drawer or something like that for probably around forty years or so, resulting in this strange phenomena.
Of course, I knew when I loaded the camera, that this film might not turn out at all!
So I didn't use it for anything important, just a fun little experiment.
Still I think I'm going to making a print or two, just to see how it will be!
Another little challenge in the darkroom!
Here's a few pictures of the film (taken with my cell-phone..) :
I think that looks good considering!
Just caught up with this thread...
This film could well be over 40 years old, I see you got something off it so well done.
As always the advice was good I would have said rate it at 100 iso and dev for 12 mins in ID11 / D76
As you say it was just a bit of fun...so fine...
