Living in the northern hemisphere of this planet, we look forward to June 21. Not only is it the start of summer, but it's also the longest day of the year, which makes it the perfect time to start a Solargraphy project. For the unfamiliar, Solargraphy is the ractice of using a pinhole camera to track the sun as it moves across the sky. Exposures are made through miniscule apertures, with the light landing directly on photo paper. Traditionally, the objective is to keep track of that giant life-giving fireball for an entire six month cycle, during which it will create an incredible array of paths on your solargraph. It's a relatively inexpensive project and, if you're lucky (and patient) the results can be quite impressive like the image above by Justin Quinnell.
