Explanation:
This persistent
six month long exposure compresses the time from
solstice to solstice
(December 21, 2018 to June 16, 2019) into a single point of view.
Dubbed a
solargraph, the
unconventional picture
was recorded with a tall, tube-shaped pinhole camera
using a piece of photographic paper.
Fixed to a single spot
at Casarano, Italy for the entire exposure,
the simple camera continuously
records the Sun's daily path as a glowing trail
burned into the photosensitive paper.
Breaks and gaps in the trails are caused by cloud cover.
At the end of the exposure, the paper was scanned to
create the digital image.
Of course, starting in December the Sun trails
peak lower in the sky, near
the northern hemisphere's winter solstice.
The trails trails climb higher as the
days grow longer and the June 21st summer solstice approaches.
