Coffee… is there anything you can’t so?

We knew instant coffee was good for something. The folks at Make just demoed a rather novel method for developing negatives from a roll of black and white film — you remember film, don’t you? Known as Caffenol, the process involves a smattering of household substances, including Vitamin C powder, instant coffee (caffeinated only), good ole H₂O, and Cascade. Of course, it’s not as simple as throwing this stuff in a slosh bucket with a roll of film and mixing it up, but it’s not that complicated, either. If you’re looking for something to do with those instant crystals, and still have a non-digital cameralaying around, hop on past the break for a homebrew tutorial.
