Method and apparatus for photographically recording an image
First Claim
1. A photographic imaging apparatus, comprising:
- 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, the photographic imaging substrate including;
a light passing substrate;
a photosensitive agent capable of producing oxygen in the presence of light, the photosensitive agent being supported on the light passing substrate away from said opening, and exposable to light passing through the light passing substrate from the opening; and
an oxidizable surface positioned in close association with the photosensitive agent, the oxidizable surface being chemically reactive in the presence of oxygen produced by the photosensitive agent to yield a visual change in the form of an image.

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.

10. A photographic imaging substrate, comprising:
-
a light passing substrate;
a photosensitive agent capable of producing oxygen in the presence of light, the photosensitive agent being supported on the light passing substrate, and exposable to light after it passes through the light passing substrate; and
an oxidizable surface positioned in close association with the photosensitive agent, the oxidizable surface being chemically reactive in the presence of oxygen produced by the photosensitive agent to yield a visual change in the form of an image. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of producing a photographic image, comprising:
-
placing a photosensitive agent capable of producing oxygen in the presence of light on a light passing substrate;
positioning the photosensitive agent in sufficient proximity to and in atmospheric communication with a corresponding oxidizable surface wherein the oxidizable surface is chemically reactive in the presence of oxygen to yield a visual change; and
exposing the photosensitive agent to light that has passed through the light passing substrate for a sufficient time to generate an image in the oxidizable surface. - View Dependent Claims (17, 18, 19, 20, 21, 22)
