If you're still shooting pictures with film, you'll know how difficult it can be to find your favorite these days. But what if you can make your own film?
Flickr user dark orange has posted a set of images documenting and teaching interested readers how to make their own film-making machine ("plastic and goop go in one end, and camera film comes out the other end"). Being a film user myself, one advantage I can think of for having such a piece of hardware is the ability to create the type of negatives I like. This is especially important as I'm not sure when Kodak will stop producing its Tri-X black-and-white negatives, considering it earlier this year.
Instead of making this a solo project, why not gather a few friends to make this machine? Who knows, you may even be able to sell a couple of rolls for a decent profit.
