ABSTRACT:
A two-stage 3D printer comprises an edit stage in which a key subject is selected and image color data and key subject registration data are generated from negative 2D images and a print stage in which those data are used to optimize exposure of the 2D images and to provide key subject registration of the 2D images on lenticular print material. Exposure control and key subject registration in the print station are fully automated. The only required operator intervention in the operation of the printer is selection of a key subject of the photographic scene in one of the 2D images at the edit station.
