Solargraphy

 

By using light sensitive photographic paper and a simple pinhole camera, you can record the sun's path through the sky over very long periods of time. Here you can find how to make a similar pinhole camera.

My first test, taken from my balcony during a couple of weeks. I managed to put the paper backwards in the can, but apparently it still works more or less. The intensity and sharpness are just a lot lower and you have to tweak more with the levels function in Photoshop.

 

My second test, taken from my balcony during approximately three weeks.

These three photos were taken over a period of nearly six months. Starting at the top of the picture is the sun on June 22nd (with the sun at its highest point), and at the bottom is the sun at December 6th, just two weeks before it reaches its lowest point. I was forced to retrieve the cans before the 21st of December because of increasing amounts of snow, which would have prevented me from reaching this area if I waited any longer.

This one got damaged by water in the can, giving an interesting look to the photo. (2014-06-22 until 2014-12-06)
