Make pinhole cameras from drinks cans and Tetra Packs, then load the camera with photographic paper to make a pinhole exposure over a day, a month or 6-month duration.
To see some of the original solarigraphy have a look at Diego Lopez, Pawel Kula, Slavo Decyk and also Tarja Trygg's Solargraphy project. For other pinhole camera designs and adventures have a look at Justin Quinnell's www.pinholephotography.org
Where can I buy the materials to make a Solargraph?
Can you do the whole thing using small cans or does it have to be the larger ‘beer’ cans?
5”x7” paper fits perfectly into larger drinks cans (usually 440ml). If you want to use a small drinks can, such as a coke can (usually 330ml) you’ll need to cut your 5” x 7” paper down to size before putting it inside, ensuring there’s enough space for the pinhole to expose the paper.
What direction should the camera face - east, west, north or south?
in Northern Hemisphere, North in Southern Hemisphere.
Point upwards around midsummer but you can also experiment with East and West if you’re doing a 1 day exposure during midsummer.
