To make sort, you mix washing soda and instant coffee, add a bit of ascorbic acid (vitamin C) and Bob’s your uncle.
This summer I imagined that back in Singapore for a couple of weeks without the family I could replicate this success. Alas, on the 4 films I have processed, none came out very good. My original recipe was dosed for the washing Soda that can be found in France, and I am not sure the one I can find here is dosed the same way. What about the quality of instant coffee? And the temperature of the tap water?
So I tried to process 4 films and this is what I got:
– film num.1: TMAX 100 from holidays in France: I used the original recipe, film goes out bad but I could scan it and post some of the picture in flickr or in my 24th of July post here
– film num.2: ILFORD PAN 400 from photo-tour in Arab Street with Singapore Photo Walker group, taken with the Kiev IV : I reduce the soda and used 60-70% of the original: the film is almost unusable and you’ll find the pictures below. I could not scan it, I had to shot the negatives with my DSLR using a flash gun to back-light the film.
– film num.3: Fuji Neopan 100 : supposed to be Caffenol friendly: I shot the film (only 12 shots in Medium Format) in Chinatown one afternoon with the old Agfa Isolette III. Film goes out very dark, but when digitized with the DSLR method, pictures are ok; unfortunately the focusing of the Agfa doe snot works ! Argh!
– film num.4: Rollei RPX 100: my lastfilm of the holidays in France: I try another recipe and got a total black film. Bouh ouh
Not much lessons to take from this. But I’ll try again sometime
