You can probably shoot just about any photograph you need with a smartphone, but if you're looking for a slightly more experimental photo adventure, why not make your own camera?

Princeton Architectural Press asked one of its authors, photographer and DIY pinhole camera expert Chris Keeney, to share his tips on making a pinhole camera out of a coffee can.

You’ll need a coffee can, a small needle, magnet tape, and a few tools. Once you've gathered those materials, you just need to drill a tiny hole in the coffee can where light can shine through. Then, you use the magnetic tape as the shutter, sticking it to the metal coffee can over the hole. The film negative goes inside the can with the lid on.

Intrigued? The full directions and materials list are on Medium, or you can pick up a copy of Keeney's book, Pinhole Cameras A Do-It-Yourself Guide for $20.
