Caffenol: DIY Coffee-based Film Developer [Video]

Inspired by our film photography guide to get started shooting film? You can add a fun DIY twist with this home brewed photo developer.

In the above video Matt Richardson from Make Magazine shows us how to make our own homemade photo developer using simple household materials (like coffee, washing soda, and Vitamin C) combined with cheap development supplies like a film reel. Whether your aim is being an eccentric photographer or being able to develop photos if stranded in a backwater local with no photo lab on hand, it’s quite an interesting technique.

Skill Builder: Caffenol Homebrew Film Developer [Make]

Jason Fitzpatrick is a warranty-voiding DIYer who spends his days cracking opening cases and wrestling with code so you don't have to. If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.

    I have found Caffenol to be a great way to add some diversity into film developing. With some films it stains the emulsion and you get warm negative. My favorite is shooting Fuji Acros 100 at ISO 50 and developing it in Caffenol.

    OK, so that’s a total of *two* people (Matt Richardson and Art) who still use film cameras.
