Explanation:
If every picture tells a story, this one might make a novel.
The six month long
exposure compresses the time
from December 17, 2007 to June 21, 2008 into a single
point of view.
Dubbed a solargraph,
the remarkable image was recorded
with a simple pinhole camera
made from a drink can lined
with a piece of photographic paper.
The Clifton
Suspension Bridge over the
Avon River Gorge
in Bristol, UK emerges from the foreground, but
rising and setting each day
the Sun arcs overhead, tracing a glowing path
through the sky.
Cloud cover causes dark gaps in the daily
Sun trails.
In December, the Sun trails
begin lower down and are short,
corresponding to a time near the northern hemisphere's
winter solstice date.
They grow longer and
climb higher in the sky as the
June 21st summer solstice approaches.
