Usually, when making a three-dimensional photograph by using this lenticular lens, it is possible to use a photographic lens having a slightly different photographing angle.
A lenticular lens in a printer that shoots a subject with a camera that has about five lenses and prints multiple frames on a negative film shot with these lenses so that the main part of the image is printed at one point. Is printed on photographic paper through.

For this reason, when a three-dimensional photograph is produced by a printer, each photographing piece on the negative film is accurately moved to a position required for image quality design, and the negative film is formed a plurality of times according to the number of photographing pieces. Direct exposure to photographic paper was required.
