Do you want to take long exposure images for days, weeks or even months?
Solargraphies (pinhole images on photograhic paper that capture months of the sun arching across the horizon) were a thing starting sometime in the 200Xs and this got a lot of people excited for film again. Quite a few people apparently started dropping cans with paper and pinholes in woods and the public urban space and I very much like this idea.
But how can we move the art of solargraphy into the digital domain?
