Abstract
Abstract A method of exposing an integral imaging element having: an integral lens sheet with opposed front and back surfaces; and a light sensitive layer positioned behind the back surface; the method comprising the steps of: exposing the light sensitive layer with light from behind the back surface; wherein the element additionally has an anti-halation layer on at least a portion of the front surface of the lens sheet which anti-halation layer, during exposure, reduces the amount of exposing light which would otherwise be reflected back toward the light sensitive layer from the front surface. A system which can use the above method, and an integral image element of a type which can be produced by it, are also described.
