Research to date, May 2019.
Here is presentation I made at Matérialité, esthétique et histoire des techniques : la collection François Lemai comme laboratoire, Université Laval (Québec), in May 2019
I first started looking for processing alternatives in 2015. I had just finished a processing about 800 feet of 16mm in the bathroom of my flat in Montreal. I took numerous precautions to be safe but still found that working with those chemicals in my living space felt unhealthy. I stumbled onto caffenol and the story of Professor Scott Williams at the Rochester Institute of Technology on Ney York. See that story here: caffenol.
Additionally I found a sub-culture photography group that was refining the process for their own personal projects. It’s within that group that I discovered the caffenol cookbook.
With those resources I set out to experiment and see what type of results I could achieve. Here are some of my early results.
Here is a link to some photos of my prototype for vertical tank immersion.
