Hi all the PDMLers who are wanting to push the limits (6800mm TC'ed comes to my mind ;) Remember when I wrote about ISO 3 film - ORWO DK 5, and was sad because Foma Bohemia discontinued another similar film Dokument Pan, leaving me with nothing else but few rolls of DK5 in freeze and desire to experiment more? Tech Pan is just too expensive for that sort of fun. Well, I just got about 50m (150') of B&W Sound recording film (from a friend in movie industry), of God knows what make. It's still good, working! Interesting emulsion with my tests' estimated speed around 1-10 ISO at normal gamma, depending on developer (it produced thin shadows and blocked highlights when exposed as 25 ISO and developed in paper developer, resulting in very contrasty negs - about 3-4 stops range only !!!). The grain is impressive - there is no grain at all (at this speed, it would be a miracle to be grainy!). I am looking into making this film less contrasty - propably with pure Metol as developer, or the Coffee "developer" (said to be very compensating. but would need propably about full day in the stuff to develop :) I hope this is interesting for somebody :o) It presents another option for those wanting to try odd emulsions (ask for sound recording film) and super-low-iso, super-low-grain films (usable as super-high-contrast low-grain moderate-low-iso film as well, if developed that way). But beware of Kodak's one: I heard it has got huge "Kodak" printed across the middle of the emulsion. After all, in sound recording AFAIK only a side of the film is used. Some sound rec films aren't even coated evenly - only a half has emulsion on it. BTW, in the Ilford's MG paper dev, the neg was developed to almost NONE fog! Had I a densitometer, I could measure it, but from simply looking, the base/fog density is SOOO small! With highlight density pretty high (this is a very high silver content film, imo) Frantisek (happy :o) - This message is from the Pentax-Discuss Mail List.
