Primitive Holography

Gene Youngblood's introduction to Holography is an interesting one. His Expanded Cinema text seems to portray every kind of emerging, innovative cinema platform and Holography is one of these aspects. He provides examples of early projections that give the illusion of a hologram. I use the word "illusion" since it is truly not an actual hologram that contemporary audiences would recognize. Rather, it is a system in which it is limited to one or two viewers. The projected hologram is then catered to an individual's perspective by providing multiple renders of an object or objects. This method uses parallax to give the sense of Holography. There are other means of providing a holographic element that Youngblood describes. Technical artists utilize laser beams in conjunction with smoke. The smoke captures the light, and when used with multiples of lights, it gives depth to the image, thus giving the viewer a sense of Holography. I enjoyed reading about this. It provides a comparative view of how we create and see 3D movies with the early non-CG method of holography.
