[7] Early holograms used silver halide photographic emulsions as the recording medium. They were not very efficient as the produced grating absorbed much of the incident light. Various methods of converting the variation in transmission to a variation in refractive index (known as "bleaching") were developed which enabled much more efficient holograms to be produced. [8] [9] [10] And sensitivity across the visible spectrum allows one film to be used with a variety of different laser wavelengths, or for full-color holograms.

The progression of lens design for later emulsions is of practical importance when considering the use of old lenses, still often used on large-format equipment; a lens designed for orthochromatic film may have visible defects with a color emulsion; a lens for panchromatic film will be better but not as good as later designs. Instant Film plates are a completely dry process. No wet chemicals, no mess, no cleanup, and did we mention no chemicals! You can make holograms right at home or in standard classroom. Full-Color Sensitive When the hologram is illuminated by the original reference beam, each of the individual zone plates reconstructs the object wave that produced it, and these individual wavefronts are combined to reconstruct the whole of the object beam. The viewer perceives a wavefront that is identical with the wavefront scattered from the object onto the recording medium, so that it appears that the object is still in place even if it has been removed. Kodak announced on January 5, 2017, that Ektachrome, one of Kodak's most well known transparency films that had been discontinued between 2012 and 2013, would be reformulated and manufactured once again, in 35mm still and Super 8 motion picture film formats. [57] Following the success of the release, Kodak expanded Ektachrome's format availability by also releasing the film in 120 and 4x5 formats. [58]

Holography can be thought of as somewhat similar to sound recording, whereby a sound field created by vibrating matter like musical instruments or vocal cords, is encoded in such a way that it can be reproduced later, without the presence of the original vibrating matter. [15] However, it is even more similar to Ambisonic sound recording in which any listening angle of a sound field can be reproduced in the reproduction. Japan-based Fujifilm's instant film "Instax" cameras and paper have also proven to be very successful, and have replaced traditional photographic films as Fujifilm's main film products, while they continue to offer traditional photographic films in various formats and types. [59] Reusable film [ edit ] Just like with a photograph, the result of this process is a piece of film that has recorded the incoming light. However, when you develop the holographic plate and look at it, what you see is a little unusual. Developed film from a camera shows you a negative view of the original scene — areas that were light are dark, and vice versa. When you look at the negative, you can still get a sense of what the original scene looked like.

Silver halide crystals can be made in several shapes for use in photographic films. For example, AgBrCl hexagonal tabular grains can be used for color negative films, AgBr octahedral grains can be used for instant color photography films, AgBrl cubo-octahedral grains can be used for color reversal films, AgBr hexagonal tabular grains can be used for medical X-ray films, and AgBrCl cubic grains can be used for graphic arts films. [13] To record a hologram of a complex object, a laser beam is first split into two beams of light. One beam illuminates the object, which then scatters light onto the recording medium. According to diffraction theory, each point in the object acts as a point source of light so the recording medium can be considered to be illuminated by a set of point sources located at varying distances from the medium.

For a better understanding of the process, it is necessary to understand interference and diffraction. Interference occurs when one or more wavefronts are superimposed. Diffraction occurs when a wavefront encounters an object. The process of producing a holographic reconstruction is explained below purely in terms of interference and diffraction. It is somewhat simplified but is accurate enough to give an understanding of how the holographic process works. this is what-the history of camera sales looks like with smartphones included". www.petapixel.com. 9 April 2015.
