Explanation:
From January 11 to February 25 2013, a pinhole
camera sat in a field near Budapest,
Hungary, planet Earth to create this intriguing
solargraph.
And for 45 days, an old Antonov An-2 biplane stood still
while the Sun rose and set.
The camera's continuous exposure began about 20 days after the
northern hemispere's
winter
solstice, so each day
the Sun's trail arcs steadily higher through the sky.
These days in the Sun were recorded on a piece of black and white
photosensitive paper tucked in to the simple plastic film container.
The long exposure produced a visible
color image on the paper that was then digitally scanned.
Of course, cloudy days left gaps in the
solargraph's
Sun trails.
