<p>A light control system includes a switching means, a sensing transmitter, and a flash device, connected serially, with the sensing transmitter connected to the flash device by only two wires. The switching means is selectively operable for providing a contact closure to effect the apparent production of a light from the flash device for the illumination of a scene to be photographed. Gating means is responsive to a signal indicative of the firing of the flash device to activate the normally insensitive sensing transmitter to receive light from the scene. A signal to effect the apparent termination of the light provided by the flash device is generated by the sensing transmitter when sufficient light is received from the scene. Dynamic anticipation means provides a time varying compensation for the light intensity-time variation characteristic of flash devices.</p> |
