Under exposure and fade indicator

摘要

To inform the operator of a motion picture camera of under-exposure and the status of a fade operation, an indicator circuit is provided. The indicator circuit is in circuit with an automatic exposure control system which adjusts the diaphragm for correct film exposure under varying light conditions and an electronically controlled fade system which adjusts the diaphragm for a fade-in and fade-out sequence independently of the varying light condition on the subject.
