Kodak 400TX Caffenol Test

As you know I’ve been doing a lot of testing with Caffenol C in preparation for my book The Photographer’s Coffee Break but this morning I needed to run a quick test with Caffenol (no C) and Kodak 400TX… the results are really nice. With the Caffenol you get a usable film speed around 100 with nice contrast and grain… what’s not to like? Additionally, I have been spending time testing different methods to eliminate edge density which is very common on Caffenol and Caffenol C processed films- this morning I think I nailed it… more testing this afternoon but this image had no edge density which my previous tests with this film and others did have.

  1. Hurry that book along. I am anxious to try this approach with some widelux negs. I think that it could be just the ticket for pan negs.

  2. Yep, its that edge density (higher density on the edges) that holds caffenol back. I have been experimenting by varying my agitation regimen, trying different recipes (varying the ratios of coffee, soda, vitamin-C), and going to higher dilutions, all trying to get more even images. But so far I haven’t hit on something that works consistently. Maybe I will try pre-soaking next (don’t normally do that), and see if that helps.

    In any event I am looking forward to hearing what you come up with. Keep up the good work!

    1. The good news is that I have developed a method to eliminate edge density, the bad news is that it won’t be out till the book is released in a few weeks… stay tuned… and a presoak does help but it is only one part of the solution / fix.
