Last Year, around the time of the Autumnal Equinox I embarked on a Solargraphy project. Solargraphy is a technique where a fixed pinhole camera is used to take a very long exposure (anything from a few days to a few months) on photographic paper. The idea is that the paper will record an image of the path of the sun as the seasons change.
The pinhole cameras used are very lo-fi and simple to make. For this project my cameras were simply two soft drink cans with the tops cut off then stuck together with a piece of photo paper inside and then sealed up with duct tape. The exposure was made by simply putting a pin prick in front of the camera. After that it was just a case of finding the ideal spot to put them .
Altogether, I positioned fifteen all around North Connemara, attaching them to trees, fences and sign posts with duct tape and cable ties. Out Of fifteen, only four went missing (which was less than expected!). The first two cameras I retrieved were back in January. I would have ideally left them longer but unfortunately a tree fell and landed on top of them during Storm Eleanor, so I brought them home to see if anything could be salvaged from them.
It wasn't a total disaster, something had clearly been captured on the paper and the trails of the sun were clearly visible. All I had to do now was patiently wait to collect the rest of them. The plan was to wait until the Spring Equinox, but I couldn't resist the temptation and last week began harvesting them.
Below is a collection of the results of my three to four month exposures. Unfortunately, moisture got into some of the cans and affected the images but I quite like the distressed effect it gives. I plan to have another crack it this from the Spring to Autumn Equinox to get a much bigger arc as the sun sits much higher in the sky and hopefully learn from my previous mistakes regarding positioning and water proofing. You will be able to see the results of these around Halloween time, but knowing me it'll probably be around August some time!
