Abstract
An improved image transparency or slide is disclosed in which certain small image anomalies are rendered invisible to the human eye in an image projected from the slide. A diffusion layer spaced a finite distance from an image coating of the slide causes disappearance of the anomalies in a the projected image. In applications requiring particularly high sharpness, the image is formed on the slide using image enhancement techniques which produce exaggerated edge effects in the image. When these exaggerated edge effects are diffused in a projection, the projected image is sharp and free of the anomalies.
