I’m writing this in April 2020, while the world is locked down due to the Covid-19 pandemic. It’s World Pinhole Day today, 26th April, and I wanted to do something to represent the strangeness of the last few weeks, which have been spent at home with only occasional forays outside.
I decided to make a camera specifically for the event, rather than using one of the many pinhole cameras that I already have. Baked beans have been in short supply during the lockdown, with many people panic-buying tinned food, so I liked the idea of getting “full use” from the baked bean cans I had. So I sprayed an empty can stealth black, and added a laser-cut pinhole which I found in a box of junk and happened to be about the right size for the focal length. The camera has a focal length of 70mm and a pinhole diameter of 0.3mm, giving an aperture of f/235. A card lid was added to make it light-tight.
The exposure was around 30 seconds on Ilford Multigrade IV paper. I then contacted-printed the paper negative to give a positive, scanned it and added some colour in Photoshop.
