How to Develop Film Using Coffee and Vitamin C

Here’s a step-by-step video tutorial teaching how to develop your B&W film using instant coffee and powdered vitamin C instead of actual developer. You’ll still need some darkroom gear and some fixer, but it’s a neat way to experiment with film photography. Photo geeks call this solution Caffenol, and there’s even a special Flickr group dedicated to making homebrew developer.

If you’ve never learned how to process film, this is also a great introduction to how it’s done.

    they should add to the video that you can use this method only for black and white film…

    Develop in coffee…then tone in tea!

    People do process color (C-41) film in caffenol just as people develop color film in black and white chemicals.  It’s called cross-processing and gives interesting results, though not in color.

    The tubular center column was put upside down in the tank – the end of the tube with the flange goes at the bottom. This is important for making sure the tank is light tight!!

    Got to read the directions for the developer tank. The light trap was inserted upside down. Not good.

    And make sure to put a 2nd reel on top to keep the lower one from coming up out of the developer liquid!  This can lead to uneven developing.
