Photographic illuminating system with reflector - has ellipsoidal reflector with halogen lamp displaced along optical axis

摘要

The film and photographic lighting arrangement has an ellipsoidal reflector and an electrical lamp. The lamp can be adjusted along the optical axis. The reflector curvature is specified by a formula. The lamp and reflector can be shifted relative to each other a max. of 15 mm. along the optical axis. A halogen incandescent filament lamp is used. The system is displaced dependent on the use of a telescopic objective or wide angle objective in the camera.
