Date Dec. 3, 1987.A slide projection screen is disclosed which is designed to facilitate video recording of projected images. To accommodate for varied light intensity levels, the screen resulting from the optic projection by a slide projector, a compensating layer is provided on the screen. The compensating layer is made by preparing a master film image corresponding to the average light intensity pattern from a slide projector and using the master film image to expose a photo emulsion layer on the screen being made. Certain embodiments include a light absorbing layer to compensate for light scattering halation effects.
