Introduction to 3D Photography for Lenticular Printing

Learn lenticular 3D photography and rendering methods for scaled lenticular printing. Lenticular photography made simple.

An animation known as a perspective sequence is produced that can be processed into a 3D lenticular image. A perspective sequence is an animation where a scene is captured/rendered from a series of locations. The different locations provide the perspective views used to create the 3D lenticular image. There are many methods that could be employed to create working sequences. The method described here is for creating sequences using a camera mounted to a linear motion track, in the case of computer 3D rendering the track is simulated. An alternate method uses a rotational stage on the camera track. Linear motion is prefered over rotational motion since it yields more realistic depth. The only advantage of rotational is that no realignment of the aim point and cropping are needed. The main disadvantage is that the aim point can not be realigned.

Basically, the camera is mounted to the track perpendicular to the linear motion of the track. It is positioned at the center of the track during the composition of the scene. The camera is then moved to a predetermined position left or right of center and moved to the opposite side of the track while capturing images at evenly spaced locations. The distance that the camera moves and the number of images captured is the focus of this sub-site with particular attention to creating images of a predetermined size using a linear motion track.
