We knew instant coffee was good for something. The oldsters at Make just demoed a slightly novel method for developing negatives from a roll of black and white film — you remember film , don’t you? Which is called Caffenol, the method involves a smattering of household substances, including Vitamin C powder, instant coffee (caffeinated only), good ole H2O, and Cascade. For sure, it isn’t so simple as throwing these things in a slosh bucket with a roll of film and combining it up, but it isn’t that complicated, either. In case you are searching for something to do with those instant crystals, and now have a non-camera laying around, hop on past the break for a homebrew tutorial.
