Develop your film in coffee

[sirius]

Here's an interesting technique. I wonder which works better, folgers or Nescafe.

I've had the same idea of developing in coffee (after a recent posting here on rff).

Could you push process with espresso?

Fomapan develops better in Staropramen, Pilsner Urquell or Gambrinus.

Well a variation on the camera and coffee thread, cassette in Starbucks coffee mug with dowel key in centre and startled waitress when you ask for the fast fixer, after a quick rinse.

I imagine yes! On the other hand diluted might give better edge effects and accutance, no?

Incidentally, we tried this once using Turkish mocca, with a roll of Foma 100, to boot. Just coffee won't do the trick, we got a blank, slightly brownish roll out of it. Apparently you have to add some alkalic agent such as soda to get the reaction to work.

This topic seems to be popular, as it recurs fairly regularly both here and on p.net. While I haven't tried it myself - right now, I have too many films to develop that I don't want to risk - I have seen some interesting results from the process. As can be seen from the samples on that website, good tones and fine grain are definitely possible.

yeah! I need to try this!

I used coffe (nescaffè - cheap version) and I didn't obtain good result but develop with coffee "aromna" in darkroon is a great experience and my wife permits to me to work in my kitchen

The recipe indeed demands the use of soda.

I'm wondering (and showing off my lack of knowledge at the same time)... the recipe on http://www.digitaltruth.com/techdata/caffenol.php , is that for iso100 film or can I use it for film of any speed?

I have both iso100 and iso400 B&W film that I want to experiment with and it just occurred to me I might need different amounts or developing times.

Does anyone have an answer?

 

[RML]

Anyone? Pleaaase....

I wonder if you can use 6 spoons of baking soda instead of the 3 spoons of washing soda?

Dear RML,
I read a report on that developing technique and - if I remember well - it was recommended also for 400 ASA. I may check my files and give you an exact answer, if you like.

Here is an interesting report:

One more thread on this?

Not the same soda. refer to the link for digitaltruth from RML. It details why you need to either get the washing soda, or the appropriate chemical compund for use.
