Luminumbra is a word I invented to describe images formed on empty surfaces when light passes through translucent objects.
As in: ripples of light on a white table cloth next to a glass of water, brilliant colors cast on the floor after light passes through a stained glass window, webs of light and shadow formed when bright light passes through a crumpled plastic bag, swirls formed on the ceiling after light passes through a blown glass sphere, slats of brightness on a dark wall when light passes through vertical blinds.
Luminumbra Project is essentially photographs of light cast on blank canvas, walls or paper.
Some luminumbra project images contain the light source or object used to create the luminumbra - if so, these are noted.
Pure luminumbras are photos containing nothing more than blank surfaces momentarily graced with intangible ripples, patterns or clouds of light or color.
A luminumbra is often light cast into a dark area, but they often include shadows. Shadows are not luminumbras unless they contain elements of luminousity within the shadow.
Luminumbras must be intangible. The image may contain the object used to create the luminumbra - but that item - such as a sphere of glass lit from within - is NOT a luminumbra. The luminumbra is the ripples of light on the wall behind the glass sphere.
The first images shocked me. A strange, moonlike vista emerged and I thought to myself - this is a photo of a BLANK piece of paper.
