Abstract
A photographic lighting apparatus for consistent and accurate exposure control of a subject before a camera. The apparatus comprises a plurality of light sources, a power supply; a plurality of switches, and a controller. The switches are connected to the plurality of light sources for selectively providing power from the power supply to the light sources. The controller sequentially operates the switches and has user-programmed operational control for manipulating the light upon the subject to create a desired illuminating effect. This sequencing operation of said controller produces accurate exposure of film within the camera.
Claims12
A photographic lighting apparatus for consistent and accurate exposure control of a subject before a camera with an open shutter comprising:
- a plurality of light sources for illuminating said subject;
- a power supply;
- a plurality of switches respectively connected to said plurality of light sources for selectively providing power from said power supply to said light sources;
- a controller for operating said switches, said controller having user-programmed operational control for manipulating the light upon said subject to create a desired illuminating effect, whereby the operation of said controller produces the desired exposure of film within said camera as predefined by an operator and may be repeated producing the same illuminating effect.
A method of providing consistent and accurate exposure control of a subject in front of a camera comprising the steps of:
- placing one or more lights around the subject;
- defining a sequence of operation for said lights;
- programming said sequence of operation into a central controller;
- and
- executing said sequence of operations from said controller while the shutter on the camera is open such that said central controller operates said lights according to said programmed sequence of operations and said camera captures reflections from the subject onto film within the camera.
