ABSTRACT:
A photographic imaging apparatus includes a housing defining an interior cavity, an opening at one end of the housing to allow light to enter the interior cavity, and a photographic imaging substrate located within the interior cavity opposite from the opening for receiving the light entering the interior cavity through the opening, the photographic imaging substrate including a light passing substrate, a photosensitive agent capable of producing oxygen in the presence of light, and precursor gas, the photosensitive agent being supported on the light passing substrate away from the opening, and exposable to light that has passed through the light passing substrate from the opening, and an oxidizable surface positioned in close association with the photosensitive agent, the oxidizable surface is chemically reactive, the reaction being enhanced by electric current, to yield a visual change or image upon exposure to oxygen produced by the photosensitive agent upon.
