SOLARGRAPH - SUMMER SOLSTICE Taken by Jan Koeman on June 20, 2017 @ Middelburg, the Netherlands

Happy Summer solstice! High time to open your solarcan. With a piece of photographic light sensitive paper you can make a picture of the movement of the sun along the sky from summer to winter solstice. A photograph with a single exposure time of 6 months!Just take an empty beercan and pin a hole to make a pinhole lens.
