Method and apparatus for composing 3D photographs
A 3D photographic printer uses a monochrome panel for displaying two or more images for composing a 3D photograph. Each image has a plurality of color image components. A light source with selectable color light components is used to illuminate the monochrome panel corresponding to the displayed color image components. The images are displayed at different locations so that these images can be projected onto a 3D print material through a projection lens at different projection angles. With the digital display device, it is possible to electronically locate the images at different locations and shift the images or mechanically moving the display device during the 3D photographic composing process. It is also possible that only the print material is mechanically shifted to different locations. The display device and the projection lens can be stationary.
