How to Develop Photographs with Coffee

James Hoffmann knows something about coffee. He’s authored The World Atlas of Coffee and runs a prolific YouTube channel, where he covers everything from making coffee with the AeroPress and MokaPot, to brewing the perfect espresso and also providing basic coffee making tips & tricks. Pretty bread and butter stuff, if you can use that expression when talking about coffee. But he also covers some subjects at the margins of the coffee world–like how to develop photographs with coffee. Above, Hoffmann introduces you to Caffenol, a process whereby photographs can be developed with coffee and sometimes Vitamin C. To take a deeper dive into the subject, you’ll want to explore PetaPixel’s primer, Caffenol: A Guide to Developing B&W Film with Coffee.
