Flash in Camera Viewfinder

Flash in Camera Viewfinder




      Camera designers try to make cameras as compact as possible.  The flash unit on cameras in the mid 1970’s was approximately the size of the viewfinder window.  While at Kodak, Steve Hines proposed combining the viewfinder window with the electronic flash.  




      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:
