I picked up on Eb@y a while ago some bulk b&w 35mm film. To be exact 2-400' rolls of kodak aerographic film (iso 6... yes SIX), 2-1000' rolls of Kodak Direct MP (b&w POSITIVE film.... I was floored when I developed a roll and found it was SLIDES), and 2-1000' rolls of panchromatic separation film (also about an iso of 6) these are a bit strange to figure out because neither was meant for straight picture taking. They were meant for making b&w negatives from color negatives and whatnot. I've been shooting some of it at iso 25 with "OK" results... Still trying to figure out the "sweet spot" as far as iso goes. But with 4800' of this stuff in the freezer I hope I can figure it out before its all used

Has anyone else came across either of these film stocks or any others that they would like to share?

That sound like titling film? Some copy films are also slooooow too.

What are you using for the developer?

Also, check out FPP and what Matt Marrash is doing with X-Ray films... the developer in particular.

Ive souped it in a few... microdol-x, d-76 and also hc-110
Thx ill check it out

Ive been reading that D-97 was the original movie production film developer... alas its discontinued :/ I also read that Dektol could be used instead. Do you know if this is accurate?

Copy film I recall is a very thin sort of stuff...Dektol does sound familiar. Mind, though I've been hearing the joys of copy film, I've never had the pleasure. I forget if it was 4325 or 5325, I was trying to snag a roll and see what it was about. I was rated 8-32? I was said to process in C-41 and also stand-developed well in Rodinal at about 1:200 for about hour... always wanted to try it. Exactly which one is yours... ?5360

Mine is special order stocks. As far as i recall so-202 is the panchromatic separation film, another is Direct MP not sure of the so #. The third is Kodak aerographic "space film" so-355 L/C. As far as I can tell the space film was used for shooting solar flares by NASA.
When I get home after work ill snap some shots of the cans for you to take a look.

Wow! That sounds like tricky stuck...Coool!

Yeah lol. The space film has a bright canary yellow base. Very thin. Transparent almost in bright light.must be very low in silver??

As promised

Very cool!

Yeah I have 2x each of those. Maybe I should bulk roll a few and send them to whoever is interested in experimenting.

You have some unusual stuff, that's for sure. However, if it's truly a B&W film stock, I'd suggest trying the only developer I've used for about 30 years - Diafine. It's available from FreeStyle. It's gotten rather expensive recently, but it's still a great value if you shoot and process your own stuff. It's a two bath developer, and I usually dump my gallon once a year, and I mean this - whether it needs it or not. The stuff just keeps working and working. All film gets 3 minutes in each bath. You can process ASA 50 stuff along with ASA 400, same tank, same time. Temperature is not critical, either. For people like me, with a somewhat less than "ideal" darkroom due to variables that I cannot control - it's the perfect film developer. Whatever you've got...Diafine will develop it.

I've looked into this Diafine at $42 it isn't atrocious. Maybe ill give it a go. It does however state that with some extremly slow films its problematic and the stuff I have is about iso 6... some is like 0.8-1... :/
