Potential users must anticipate how their holograms are going to be displayed before starting production. There are ways to solve these problems using good design practices, as well as technological approaches which are currently being developed by researchers worldwide. Both these issues are covered in greater detail throughout our books. How Holograms are Recorded The degree to which you can look around an object and the distance the image forms in front of or behind the film depends on how the hologram was made. The light reflects off our subject, passes through the camera lens and exposes the film.
Bright subjects expose the film a lot, darker subjects expose the film less.
The picture we see is composed of varying tones. Holography is different. It records an image in an entirely distinct way. Light from the sun and from light bulbs will not work. These sources emit light of varying frequencies with randomly varying phase.
