The authors have proposed the fogging photography showing electric field strength, as a new method of recording the image of electric field distribution on the photographic film. If a photographic film has been exposed to a light flash synchronized with application of electric field, the optical density of the developed film is decreased correspondingly to the applied field strength. Based on this phenomenon, a photographic film was inserted between a hemisphere and a plate where it contact each other, a fogging photograph showing electric field distribution was photographed. The density decrease distributions of the developed films were measured, and they were compared with the distributions of the calculated electric field. In consequence, it was elucidated that optical density distribution of the developed film correnpond nearly calculated electric field distribution in the emulsion layer, within the limits of the arrangement method which emulsion layer had been contacted with plate elertrode.
