Abstract
Abstract A photographic copy system including a portable light source accessory unit having a plurality of light producing elements. The unit includes a translucent window configured to support an object such as a film transparency in the illumination path in an area in registration with the camera and in an area out of the registration therewith for editing or other ancillary purposes. A flash bulb mounted within the lighting unit directly beneath the translucent window provides illumination of the object for photographic copying purposes and a pair of projector type lamps disposed along side the flash bulb and separated from the translucent window by a dichroic element are utilized primarily for editing and composing purposes, and include separate control elements configured for continuous operation of one lamp and supplemental intermittent operation of the other for viewing of relatively dense transparencies. Additionally, the light source unit includes a reflector accessory for surface lighting of the object, and a control system capable of varying the flash intensity over a prescribed range and for indicating when the proper charge level is achieved. The system also includes supplemental lighting elements for surface illumination of an object when the latter is properly positioned on the lighting unit.
