Explanation:
Fix
your digital camera
to a tripod, start a long series
of exposures, and you too can record star trails.
The concentric arcs traced by the stars as planet Earth
rotates
on its axis often produce
dreamlike scenes in otherwise
familiar
situations.
Fall asleep, though,
and the results might surprise you.
Setting up on a summer night, photographer Mike Rosinski
began his exposures, initially planning
to capture about 45-55 minutes worth of star trails
from his yard in Hartland, Michigan, USA.
But he dozed, only to awaken some 3 hours later to find his camera
had continued to run until the battery died.
Composing the resulting images, the graceful concentric star trails were
expected, along with light from a late rising Moon glinting on windows.
Still, as he slept on the warm night
a blizzard of yellow streaks flooded the scene, not left
by fairies
but
fireflies.
