An ongoing research in the self-developed art of Pyranography.
The name pyranograph stems from Greek, “pyr” (fire) and “ano” (above, sky) and “graphos” (writing).
Pyranography is a technique where an installation simular to a Campbell-Stokes recorder is used to create Solargraphs. A typical exposure is several weeks to six months to create a negative shadow image in wood. This technique was invented in 1897 to measure the amount of sunshine per day and is still regularly used in places where electricity is not easily available.
By using the changes in the angle of the sun during the changing of the seasons this technique can be used to make shadow images in wood.
The first days of sunshine for Pyranography @ DordtYart are in this video, in the weeks after a shadow image burned in the wood, recording both the weather and the shadows of the industrial crane overhead.
