I recently asked on a photography forum for a developing recipe to cross process C41 with b/w chemistry. I was tickled, but a little chuffed, when someone answered by giving me a link to an old post about the subject …. from one of my own posts here on my blog!
I hadn’t cross processed Poundland film to b/w for a year or two, and when I did, I used Ilford ID11. This time I wanted to use a rodinal / R09 developer, and I fancied stand processing.
For the Digital / N00b crowd. What am I talking about?
- Cross Processing. There are a number of different processes for film, and for printing. The most common three are a) C41. This is the process for developing colour negative film. Some b/w films have also been produced that require C41. b) E6. This is the process for colour positive transparencies / slides. c) True b/w negative. The oldest process that is usually still done by hand rather than a photo lab. Cross processing takes place when a photographer uses a process other than that intended by the film manufacturer. Many Lomo photographers cross (both ways) C41 and E6 in order to get bizarre colours on prints/scans. I am cross processing C41 Poundland film in b/w chemistry, because it is ultra cheapskate and tight fisted.
- Stand processing. Hand processing film involves agitating or inverting a developing tank filled with a film, and diluted solutions of developer at set intervals. Typical dilutions for example for the rodinal developer are 1:19 or 1:25 of rodinal to water. This moves the diluted developer through the film emulsions at a proven rate. With Stand processing, you use much weaker dilutions of developer, and instead of regular inversions – leave the tank standing for a much longer time. It saves on developer, allows you to have a meal or watch a movie, and is similar in some ways to slow cooking. You can be several minutes out either way without disaster.
The stand process that I ended up using this time was that as suggested by the Massive Dev Chart for XP2 C41 in Rodinal / R09.
The recommendation was 1:100. Yes, a pathetic 3 ml of Agfa Rodinal for a single 35mm film in my Paterson tank. The recommended time at the optimum 20C was 120 minutes. I put my used Poundland film in the tank. Added the very diluted Rodinal, gave it several inversions, then sat it down with a few taps to dislodge air bubbles.
I then took Anita out to the local flea pit (cinema) where we watched the Pixel movie. I returned maybe 130 minutes later. Emptied out the developer, stopped, fixed, and rinsed. Hung up the slippery brown thing to dry.
The above image is one scan. I did enhance the levels a little on the scanned image, using Gimp software, but not that much. I worked out that 3 ml of my Rodinal cost me about 8p (GBP £0.08). The film a quid from Poundland. Altogether, film, develop, fix, and scan cost me no more than £1.30.
One more thing. This isn’t just about process and cost. How does the image look?
