As I could not go out and about with my photography group for Worldwide Pinhole day this year, I decided I needed a new challange. I used my old favorite coffee can camera – which uses paper not film. My new challange was using caffenol to develop the images. I had used caffenol to develop film before with great results – so what was there to lose!!
I used a recipe from caffenol.org The Delta Recipe –
-1000ml water, 24g washing soda (65g if crystalline), 20g vitamin C, 45g Instant coffee.
-I used water a stop
-The fixer was an alkaline fixer – 10g sodium carbonate, 1g sodium carbonate, 100ml distilled water.
It was a very messy process
In keeping with using a coffee can as a camera and coffee as a developer, the whole process was very low tech. My darkroom was my bathroom and I used my iphone as a safe light – which along with the density of the caffanol mix made it hard to see when the image was developed. Most worked – very pleased.

I have slight obsession with keys – so although all the shots were outside -I had to incoroprate them in some way.
