I have bought old Ilford Polypan F Professional. It came in a huge roll so I think that this must have been any kind of kinematographic film. What you think? There are no quides how to develop and stop it. Are there any suggestion on the developing times?

Thanks

I think this might be "Pan F" European version which is a 50 ASA film. If this is the case, go to www.digitaltruth.com and you'll find a massive development chart. Just plug in the info and find a developer you care to use. Testing will probably be the order of the day just to see where this film is in the food chain so to speak. Cheers, Scott

You are right about the speed ASA 50. But the thing is that it is not produced by any of the big film companies like Ilford or Kodak. I do not even know where this film was made. I bought it in a huge roll (90meteres). I guess that this must have been some kind of a kinematographic film, but I am not sure. What is also pretty interesting is, that when I develop the film the unexposed parts (perforation) are completely clear. Pretty strange for me. I have not seen anything like this before. I had always seen these parts of the film a bit darker, not 100% clear. The other funny thing is that this film is a bit contrast for me. I am just working on the developing bath times. Trying to figure out what is the best. On the box from that film there is only suggestion what kind of developer to use. It is D11. The other thing is that there are no signs on the sides of the developed film, even no numbers no name. ?

Kodak used to offer a high contrast developer called D-11. I guess it's possible that stuff might be some sort of reprographic film, especially if it's a bit contrasty. I don't really know though, good luck...
