Dependence of the moisture of the plate on the hologram characteristics is studied for methylene blue dichromated gelatin. The maximum diffraction efficiency increases, and the exposure to obtain a sensitized amount of diffraction efficiency is reduced for the red light when the moisture of the gelatin layer is certain controlled during exposure. The photochemical reaction of the plate is briefly discussed, and the properly result of the double exposed hologram is also presented.
