Abstract
A photographic apparatus, camera, and method are used in ambient light with an archival capture media having a designated illuminant. The apparatus includes a body and an ambient light discriminator mounted in the body. The discriminator assesses a color value of ambient light. A flash firing circuit is disposed in the body. An operation circuit operatively connects the ambient light discriminator and flash firing circuit. The flash firing circuit arms responsive to a mismatch between the color value and the designated illuminant.
Claims24
A photographic apparatus for use in ambient light with an archival capture media having a designated illuminant, said apparatus comprising:
- a body;
- an ambient light discriminator mounted in said body, said discriminator assessing a color value of said ambient light;
- a flash firing circuit disposed in said body;
- and
- a operation circuit operatively connecting said ambient light discriminator and said flash firing circuit, said flash firing circuit arming responsive to a mismatch between said color value and said designated illuminant.
A camera for use with archival media having a designated illuminant, said camera comprising:
- a body;
- an ambient light discriminator mounted in said body, said ambient light discriminator assessing a color value and brightness of said ambient light;
- a flash arming circuit disposed in said body;
- a operation circuit operatively connecting said ambient light discriminator and said flash arming circuit, said ambient light discriminator and operation circuit actuating said flash firing circuit responsive to at least one of:
- a mismatch between said color value and said designated illuminant and
- said brightness being less than a predetermined level.
A flash-assisted image capture method for use in ambient light, said method comprising the steps of:
- assessing a color value of said ambient light;
- arming a flash firing circuit when said color value is outside a predetermined color value range.
A flash-assisted image capture method comprising the steps of:
- capturing an ambient light image as an electronic image in a camera;
- assessing a illuminant color value of said ambient light image;
- comparing said illuminant color value to a predetermined color value range;
- arming a flash firing circuit when said illuminant color value is outside said predetermined color value range.
A flash-assisted image capture method comprising the steps of:
- assessing a color value of ambient light;
- arming a flash firing circuit responsive to a mismatch between said color value and a designated illuminant;
- capturing a latent film image on photographic film color balanced for said designated illuminant;
- firing a flash unit during said capturing.
