Want to play around with pinhole photography by building your own cardboard camera? Photographer Raymundo Panduro of Pixel Análogo has just released a free template for building a 35mm sprocket camera.
You’ll need to cut the pieces in the template out of some durable card stock. Other things you’ll need are an aluminum can, a needle, black electrical tape, scissors, a glue stick, an empty 35mm film canister, and a new roll of film.
The instructions for putting everything together can be found in this 10-minute video. It’s in Spanish but you should be able to figure out the gist even if you don’t understand the narration (the YouTube player also has a translated captions feature):
Panduro recommends using ISO 400 film and a tripod to prevent camera shake. Here are a few sample shots showing what the camera can produce:
