    • In the improved method for projection a stereoscopic image, an additional lenticular sheet that has an appropriate level difference and a different pitch of lenticular lenses than a lenticular recording material such as a lenticular light-sensitive material is either placed directly on top of said lenticular recording material or inserted above and in the vicinity of said lenticular recording material, with said additional lenticular sheet being preferably moved either in one direction or reciprocally in a direction generally perpendicular to its own generatrix. This method can be implemented with the improved apparatus for printing a stereoscopic photograph. Using the improved method and apparatus, the development of moire can be suppressed and, at the same time, the line width of linear image elements to be recorded can be easily expanded.
