ABSTRACT:
Color control in a Denisyuk type hologram having interference fringes lying generally parallel to the substrate is effected by subjecting the initially produced hologram to resensitizing, controlled re-exposure, second development and second bleaching steps, of which the effect is to remove silver produced by the second exposure so as to enable the playback interference fringes to move closer together.
