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.

Stay tuned…

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.
Just finishing all testing tonight / tomorrow… everything is on track for completion… the process has evolved far beyond my orig thoughts… very cool!
It looks great. Really excited for the book!
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!
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.
Cheers-
