Flash in Camera Viewfinder

Flash in Camera Viewfinder




      Cameras are made as compact as possible.  The flash unit is approximately the size of the viewfinder which can be combined with the electronic flash to reduce the size further.




      The electronic flash is reflected, or slid into position, each securely blocking the viewfinder to prevent any light reaching the photographer’s eye.  The flash fires only when a micro switch is closed after the light-blocking device is in place.


      U.S. Patent 4,279,488 is assigned to Eastman Kodak but not used.  For questions, please contact Steve Hines at:
