发明名称 Camera accessory for controlling an external strobe
摘要 An easy to use camera accessory, when mounted onto a camera, will trigger an external strobe upon excitation of a built-in electronic flash while simultaneously blocking from the scene the light emitted by the built-in electronic flash. The camera accessory typically is snap-in mountable and includes: a flash slave for triggering the external strobe, a PC connector for connection via a cable with the external strobe, and openings for camera features including, but not limited to, a lens, a sonar detection device, a viewfinder and a photocell. Light emitted from the built in electronic flash is physically blocked from being cast upon the scene. A more basic version of the inventive camera accessory does not require the camera feature openings.
