Developing Negatives in Black & White with Caffenol

Chris teaches a photography class.

Awhile ago a Skillshare recruiter contacted Flickr to see if anyone would be interested in teaching photography classes and Chris jumped on the chance to share his new-found knowledge. The first two classes Chris taught were what Skillshare had asked for: Photography 101 and Instant Photography. I begged him to do a Caffenol class because it’s something I was interested in, but more importantly – something I knew a bunch of our friends were interested in learning as well. So last Monday Chris taught us how to developing negatives in black and white using the caffenol method.

The class was held at the HUB, a shared workspace under the SF Chronicle building in SOMA. Allison, Sam, Val and I were a few minutes late because we hadn’t expected a name tag process at the front door.


Chris started the class with a powerpoint. He showed some examples of photographs developed with caffenol and talked about the different time and amounts of ingredients you need depending on your type of film.

For the class, Chris shot two rolls of Ilford PAN F ISO 50 film that we developed in Delta STD caffenol recipe at 20C for 7:45.

Ta da! Film!

Chris remarked:

As you can see the negatives are extremely dirty, for better or worse. This is due to a few factors, lack of detergent/photo-flo when doing the final rinse, no gloves while loading film, some manhandling while loading film, and transporting the film on the reels.

They still look pretty cool to me. Here are my favorites from what we developed in class:

The class was fun and informative! Thanks Chris! If you would like to see the rest of the photos of the class, check out my Flickr set. If you would like to see the rest of the photos developed during the class, check out Chris’s Flickr set.
