Solargraphy is the art of long exposure photography that captures of the image of the sun moving across the sky.  These exposures can last days, months, even years.

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.

NOTE:
This design is not my original idea; I got the idea from here: http://www.pinholephotography.org/Solargraph%20instructions%202.htm

Step 1Tools and Materials

Tools and Materials
Tools:
- Can opener,
- Sewing Needle,
- Scissors.

Materials:
- Aluminum cans,
- Electrical tape,
- Enlargement paper(http://www.adorama.com/ILIS5725P3.html).

Notes:
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.

Very nice indeed! A friend and I are just starting to set these up, and we made the mistake of trying to develop our 24 hour exposure trial runs :) Hopefully ours will look as good as yours!
