Moon sets behind Dom tower
Above: Six month long exposure compresses time from solstice to solstice (21st of June > 21st of December) into a single point of view. Below: original view.
Between the summer and winter solstice I captured the traces of the sun with two pin hole cameras on our roof. For six months two drink cans taped on top of our chimney stood in the wind. Unfortunately the captured images are a bit blurred, and despite some damage to the photographic paper (due to humidity and dust) the result really surprised me.
Here are the original scans (1 and 2).
Since last #solstice the sun traced its own #dataviz above #Utrecht sky. First #solargraph attempt w/ #pinholecamerahttps://t.co/NO9qF0RMws pic.twitter.com/lcU02ineEr
