| Title: |
Diffused Light Focusing Method for Use in Film, Television, and Photographic Media |
| Abstract: |
A lighting assembly includes a Fresnel lens disposed at a controllable or
predeterminable distance from a diffuse light source. Relatively small
cutter cards are disposable between the diffuse light source and the
Fresnel lens for generating various shadow effects on a photography,
television or film production set. The light assembly enables a soft
lighting of foreground subjects, typically actors, with a light intensity
that stays relatively constant regardless of the distance of the subjects
from the composite light source, specifically the Fresnel lens.
