Light Enhancement Camera Attachment
US Patent:
4204761, May 27, 1980
Filed:
Jan 15, 1979
Appl. No.:
6/003556
Inventors:
Joseph B. Walker - Carlsbad CA
International Classification:
G03B 1700
US Classification:
354202
Abstract:
A camera attachment for providing a low level of diffuse light over a photographic film. This illumination occurs at the time of the exposure of the film. The process may be termed "flashing" and the effect is to make the film more sensitive to light.
The attachment comprises an edge-illuminated transparent disc disposed directly in front of a large aperture photographic lens. An additional annular transparent element may surround the disc. "Softness" for portraiture can also be accomplished.
