This is stunningly beautiful Ball of Light.
A beautiful inspiring story; Denis Smith.

Implementing the photographic technique of light painting,
which uses a long camera exposure to capture moving light,
Smith creates luminous, life-size geometry. At night, and
typically when it is a full moon for the ideal effect,
Smith takes to the outdoors scouting locations with
dramatic landscapes and abandoned urban spaces.
The spheres are materialized by a constant swinging
and turning motion, which, when photographed,
become stationary glowing forms. The ephemeral
movements become lasting imagery embedded into
the camera. Smith drew much of his influence for the
project from the actual spherical shape, a significant
form throughout nature present in the sun
and planets which harness strength and power.
