joram Hello! I’d like to push my Tri-X to 800, but I can’t find any development guidelines for D 76. I want 800 ASA because my Canonet can only be set up to that speed, and 800 is perfectly adequate for me. I’ve already looked for information on digitaltruth.com in the massive dev chart, and even the Tri-X datasheet from Kodak didn’t help me. Perhaps someone has some experience with this; otherwise, I’ll have to try an intermediate value based on an educated guess – at 400 the time is 9.75 mins and at 1600 it’s 13.25 mins. Many thanks! joram
bernhardmangelsgmxde I read somewhere (-> "Häusensagen"): "Develop as normal", i.e. use the time for 400.
HenningH Thanks to these films’ exposure latitude, you can underexpose by one stop and use standard processing times. The prints will show a slight loss of detail in the shadows.Best regards Henning
zensusa Hello everyone, If you know the film’s standard ISO and its corresponding development time, you can generally use the times calculated using the standard ‘push conversion factors’ listed on ‘digitaltruth’ under the ‘Push Processing’ section. Basically, all you need to know is by how many stops you have pushed the film (in this specific case, it would be 1 stop) and which type of developer you will be using (balancing or standard). Then you have your adjusted development time! In this case, the conversion factor when using a balancing developer such as Rodinal would be 1.4. You might also want to consider whether you’re working with a mixed-light or condenser enlarger. I work with mixed light (i.e. softer) and, with these conversion factors, I’m pretty close to my working method. With condenser light, the conversion factor should be chosen slightly lower; for push 1, for example, only 1.2 to 1.3! See you soon, and good luck Lothar
joram Thanks so much for the tips! :) I've put it back in at 400 for now, but I'll try the next TriX at 800 :)

TR Hi, I’ve also tried pushing Tri-X to 800 ISO. I used the multiplier listed in the Impex catalogue, developed it with Rodinal 1+25 and ‘printed’ it using my condenser enlarger. It works quite well and I’ll probably do it that way again later. Best regards, Thomas
