I've recently had the pleasure of participating Time in a Can, an international photographic project involving a solargraphic technique. A solargraph is a photograph made by leaving a pinhole camera where it can record the apparent motion of the sun in the sky over a certain period of time. For the Time in a Can project, artists on five continents made six-month exposures from the summer solstice through the winter solstice of 2011.
You can see the unique and remarkable Time in a Can Gallery here. This is my contribution:
