I have a bunch of out of date Kodak BW400 CN film medium format film. This film has to be processed with the C41 process. It is a black and white film with colour film technique. However on various places on the internet I have read people deveolping this stuf with diluted Rodinal and stand development. At the moment I don't have Rodinal but I do have HC110. You can mix that up in various different dilutions. The common one being 1+31. This is the dilution B. Then I wondered if it would be possible to stand develop this Kodak BW400CN with highly diluted HC110? Yes it is. I have made a solution diluted 1+128. First I pre-soaked the film for 3 minutes. Then I put the film in for one hour and agitated it twice. When I thought if doing so that is. The film came out pretty good. A bit less clear as it would have been with C41 processing but the Epson Perfection V700 didn't have any problems at all scanning the film. The roll of film has been shot in an Agfa Clack.
