Developing Film in Coffee
Yes the title is correct, I'm going to show you how to develop an ordinary B&W film with instant coffee granules.
Here is what you need:
1 Jar of instant coffee
1 packet of washing soda crystals
Developing tank, liquid measure and thermometer.
Firstly, when you shoot the film lower the ISO by one stop, in this case I'll be using APX 100 (Jessops pan) rated at 50 ISO.
Load the film in the developing tank in the normal manner.
Next prepare the coffee developer.
5 heaped teaspoons of instant coffee (one per 2fl oz/60ml)
2 level teaspoons of Washing Soda crystals (NOT baking soda).
300ml (10 fl oz) water at roughly 25 deg C
A heaped teaspoon looks just like thisFirstly dissolve the soda crystals in the water, their purpose is to 'unlock' the developer ingredient present in the coffee granules.
Next put in your coffee, stirring well to ensure that the coffee has been dissolved fully.
You will notice that there are a few bubbles in the mixture and bubbles aren't good for development, so leave to stand for a few minutes but no longer than 10 as the mix must be used within 30 Min's.
Pour in the mixture and agitate slowly for the first minute, then tap the tank a couple of times to disloge any air bubbles.
The process time is 30 mins so its handy to have a watch, pen and paper to note the passing time.
Agitation used was one inversion every 30 seconds.
After 30 Minutes, rinse with plain water and fix in the normal manner.
Here are the negatives:
Slightly milky looking and brownish (due to staining action of developer) and also quite low contrast but certainly printable.If you need further convincing here are some of the images.
Nice tonal detail, good grain and sharpness and although I don't think it will replace Rodinal as my main 'brew' I think you can see for yourselves that coffee is a more than capable developer.
A stimulating thought?

This is great!
Is there anything around the house that you can use as a fixer?
Well, I thought about that and there is a lot of discussion on the internet about the use of onions, sodium sulphate and sea water.
I decided to just use Ilfofix
Is the chemical in the coffee that acts as a developer found in any other beverages?
Does the type of coffee have any effect, say use strong ground coffee for more developer?
Interesting results

I'm not sure Charlie if its caffeine then tea will also do it though probably an hour would do it as it has 2/3 the amount.
As I understand the washing soda acts as a reactive agent so you'll need that in a caffeine based dev.
Looking at the negs i was surprised how well it handled the highlights and lessened contrast I'm going to try Pan F at 32ISO 30 mins next.

Hello!
I used your picture when i linked to this site at Fotofeber.se. Is that OK? Best regards!
Yes Jens anything I write or pictures is re-publishable as long as I get a credit.
I do this for anyone interested, there is no profit.
Have fun
Mark
Hi there,
Cool stuff you got. Nice take, where did you get this?
By the way, let me show you some of my works
photosorcery.com
Many thanks
Hi Jay
Thanks, I got the idea when a friend of mine said he had dermatitis from contact with Metol in his developer, so had to give up processing.
I looked on the internet to see 'alternative' developers and of course came up with X-tol, DDX etc.
But something else caught my eye a couple of sites (APUG) and one .edu site published formulae, I followed up but few people seemed to have tried it then blogged (I found shards of photography blog did)
I thought it would be fun, not just to try but actually post a guide so others could follow, showing the results.
Liked your site too Jay,
Regards
Mark
I definately need to try this when I develop my next film. But it needs to be a film that I don't really need - and oh wonder its pretty rare that films that you shot are NOT important. Well maybe the next x-mas pics;-)
cu, ben.
you might wanna check this, its developed in switzerland (not in coffee) www.paranoiaparadise.com
Ben
This is a fun exercise, not one to be tried on a wedding or lifetime shot.
The way I approached it was to use an expendable film- shoot a few tests and have a go.
Film is cheap- experience priceless.
Thanks for commenting. checked you site, very nice.
Mark
but your idea is great and that is what counts - where would we be without people like you, having ideas that are on the edge on insanity;-)
Ben.
Ben sometimes in an insane world obsessed with Mega this, Giga that- you've just got to try stuff, have fun and not worry.
In the UK we have a saying try everything once, except incest and Morris dancing.
Byeeee
I had it posted on my blogg too...

In my link you will see that HC Bresson already did this kind of processing in the post war period. I guess because developer must have been hard to come by!
Congratulations. You are gifted.
Thanks
I'm not sure I'm gifted, just that i enjoy having fun, film or digital, fun is what its all about.
BTW I like your collection of Russian rangefinders.
Mark
Wonderful blog.
Does this work with ordinary color film as well? I mean of course it will turn black and white, but does it develop?
I doubt it would work that well for colour film, it wouldn't turn it B&W either.
Colour film has an orange mask so that isn't going to make it B&W.
I think this method works well with ordinary B&W films (which are cheap) especially the slower films 25-100 ISO but remember to overexpose for at least a stop.
Okey, that makes sense. What is the importance of the fixer? What do you get if you skip the fixer step? Do you pour out the developer from the tank and just replace it whith the fixer? And how long do keep the film in the fixer? (Thanks for a great article by the way)
You fix the film as normal. That is after you pour out the coffee/soda solution, you then rinse the film with water. Then fix for the required time (normally 5 mins or so) in a normal fixer, Ilford, Kodak etc.
Without fixing the image will fog as soon as you open the dev tank.
Do you know if there is a safe, and inexpensive developer for developing super 8 and standard 8mm
movie filmstocks; colours and black&white? anyone experimented along these lines?
John
Not really my field, but a quick google turned up this:
http://www.super8camera.com/processing.php
Plus-x is a popular B&W 8mm film so I guess you can use similar developers.
Mark
THIS is the article that convinced me to go buy B&W chemistry and developing equipment.
Thank you so much. I have shot B&W intermittently for 8 years, but have never done any darkroom work myself.
Amazing blog, read up all of it the day I stumbled by- and will keep checking for more.
To repeat- great stuff, and thank you!
Greetings from India
Thank you
developing your own is fun, and gives you control over the effect you'd like to obtain.
With so many films and developer combinations years of fun can be had.
My advice though to a beginner would be:
Be consistent with developer and agitation.
Try to pick one or two film and developer combinations and master them.
Meter for the area in the neg that you want detail to start appear then close down to stops.
Have fun!!!
my son is doing this as a science fair project and we need to know, once the film is shot and removed from the camera, do we remove it from it's hard case to develop? If we don't have access to a developing container, is their something else we can use? Is it ok to touch the negatives while processing?
Hi Jeff
Yes you need to take the film out of the cassette, which must be done in the dark (cupboard under the stairs at night with a coat along the bottom of the door) zero light must reach the film while loading the tank.
Developer tanks can be found for £2-£5 there are loads second-hand. You really need them, I'd advise against processing in the dark in trays as the process will take 30+ mins and needs good agitation.
You can see what you need to develop a film here

Good luck
Mark
this is great and i really wanna try it. i assume dev times should be increased massively if the films standard rating is 400 but was shot at 800?
Max I doubt you could use the coffee developer to 'push' films.
In fact if you are using 400 I'd rate it at 200 EI as the developer has a low contrast speed reducing effect which is great in really high contrast lighting.
I think you could mess about with the mix of coffee/soda slightly and possibly the times +/- 5 mins but I'm not sure pushing would work.
But hey give it a go, but I'd try the standard mix/time/lower speed rate first, get a feel for how it works before deviating.
The mix I used for this post is slightly different from the standard one, but it worked best for me...
Excellent to come across your post (via BoingBoing)! I have not shot film in years but just came across a film tank and instant coffee developer sounds like so much fun! I cannot for the life of me remember what the differences are between film and paper developers, but do you think it conceivable that one could develop paper in the same manner, albeit in trays? The develop time would be slow indeed, and the solution would prob oxidize quickly, but it might be interesting as an alternative process.
Thank you for the inspiration!
Brandon You're welcome.
Yes you can develop paper in coffee too there is a user on APUG called Toffle who does just that.
Most analogue developers are just organic componds like me and you! things like household cleansers (Borax) and Vitamin C can develop film- Conventional photographic processes are here to stay once discovered they can't be un-discovered
