1. A filmless single-stage printing method for printing 3D photographs from a plurality of electronically captured 2D images of views of a scene from different viewing angles on lenticular print material having a multiplicity of lenticules, each lenticule having a longitudinal axis and a transverse axis, said method comprising the steps of: a) electronically capturing the 2D images of said scene by electronic capturing means, said capturing being performed so as to acquire 2D images of a scene at different viewing angles and to automatically maintain said scene in proper registration for subsequent printing of 3D photographs; b) electronically conveying said captured 2D images by electronic conveying means to a single video monitor with a screen for sequentially displaying said 2D images on said screen, and maintaining them in proper registration on said screen; c) projecting said displayed 2D images for exposing said 2D images onto lenticular pit material through a projection lens which is focused on said screen and at the desired locations on said print material; and d) moving the group of elements comprising (i) said projection lens and (ii) said lenticular print material in the same direction to different positions in relation to said screen of said video monitor for exposing said displayed 2D images onto said lenticular print material at the desired locations at different projection angles while maintaining said projection lens in proper focus on said screen and said lenticular print material, said moving direction being perpendicular to the Longitudinal axes of the lenticules of said lenticular print material.
