This Instructable will show you one design for solargraphy pinhole cameras. Any pinhole camera will work, but this design has a few important advantages:
- Cheap. Beer and soda cans are only "worth" 5 cents (10 in some states), and are filled with tasty beverages.
- Durable. These cans are nearly waterproof, and resistant to the weather.
- Easy to make. It only takes a few minutes to make one, and it can easily be done in an assembly line process.
This design is not my original idea; I got the idea from here: http://www.pinholephotography.org/Solargraph%20instructions%202.htm
Step 1: Tools and Materials
- Can opener,
- Sewing Needle,
- Aluminum cans,
- Electrical tape,
- Enlargement paper(http://www.adorama.com/ILIS5725P3.html).
I used 16oz. beer cans because they fit a whole 5x7" sheet of enlargement paper without cutting. You can easily adapt this design for 12oz. cans.
Last summer I tested out 25oz. Fosters cans. If you go with the larger diameter cans, you'll need another large can to make the lid.
Step 2: Build Your Camera
Thoroughly wash the inside of the can and let it dry. Once it's dry, take the needle and prick a hole halfway up the flat part of the can. The pinhole should be about 0.2mm to 0.3mm in diameter. To make loading the camera easier, place a small piece of electrical tape over the hole on the inside of the can.
Take another can and cut the bottom off, leaving about an inch or so of the flat part. This will be the lid. You should be able to press the lid onto the body with a little pressure.
