As both a photography and a coffee lover, what better way to combine the two by making a pinhole camera out of an empty Illy coffee tin.
With a 0.35 precision drilled pinhole and a focal length of 90mm (roughly equivalent to 28mm on a 35mm camera), this gives an aperture of approximately f260. I am using Harman Direct Positive photo paper to produce my images, which I have found to have a working ISO of 6 (or 8 with pre-flash), so exposure times can be VERY LONG.
For the photographs shown here I left the cameras out in the woods overnight with exposure times of between 18 and 23 hours.
