A study has been made of the application of color photography to observations of dislocation motion and other time dependent phenomena in thin metal foils by transmission electron microscopy. The color technique employed was first developed by Mueller [1] to clarify vacancy‐interstitial densities in the atomic surface planes of metal whiskers by field emission microscopy. In the present application, pairs of sequential electron transmission micrographs are first superposed optically to obtain color addition. The superposed image is then photographed using standard color emulsions. It has been found that photographic density changes in black and white which result from the movement of dislocations, bend contours, dispersed particles and like phenomens, are sensitively reproduced as a corresponding color change which is immediately apparent to the eye.
