How are images made to jump out in front of the holographic film?
As just explained in the previous response, images that protrude out in front of a piece of holographic film are called real images. Virtual image holograms are used as the masters for real image holograms. Most real image holograms are holograms of holograms. The basic concept is like the idea that a negative of a negative is a positive. In effect, when you typically make a hologram it is orthoscopic (right side out) and virtual (the image appears behind the film). If you turn this orthoscopic and virtual image hologram over the image you see is both pseudoscopic (inside out) and real (in front) since the spatial relationship of where the image is seen has flipped. If you usethis image to record a second hologram, that image will be pseudoscopic (inside out) because you are recoding the pseudoscopic image of the first hologram and virtual. If you then turn it over it is orthoscopic (right side out) because an inside out image of an inside out image is right side out and real because e
