Coke Can Camera

Now this is interesting. Back in the summer, Holly and Louis went to an event as part of the Science Festival on making a "solargraph" - a photo image of the sun taken with a pinhole camera made from a Coke* can and exposed over a six-month period.

This week, at the winter solstice, out six months was up. In a darkroom, lit only by the red glow of a rear bike light, we removed the photo paper from the cans and scanned the images into the computer. A bit of Photoshopping (a flip, a greyscale inversion and a wee tweak to the contrast) later and these are the images that came out:
