Explanation:
Transformed
into the petals of a flower, 16 exposures show the
passage of day into night in this
creative
timelapse skyscape.
Start at the top and move counterclockwise
to follow consecutive moments
as the twilight sky turns an ever darker blue and night blossoms.
Each exposure was recorded on the
evening
of April 22,
calculated to maintain a consistent balance of light and color.
Close to the western horizon on that date,
a crescent Moon and Venus are the two
brightest
celestial beacons.
Petal to petal the pair spiral closer to the flower's center.
In silhouette around the center of the twilight flower
are Sicily's megalithic rocks of
Argimusco.
