Holography Split-Beam Transmission Hologram
Physics 331A Experiment 8 HOLOGRAPHY Revised 16 May 2005. When a hologram is made, a coherent beam of light is divided so that one beam (the reference beam) falls directly onto a piece of photographic film and another beam (the object beam) is formed from the light that is scattered by an object and falls onto the same piece of film. When the two beams are recombined in this way, they make an interference pattern which is recorded on the film. If the film is illuminated with coherent light, the light will be diffracted as if by a diffraction grating, giving rise to a diffraction pattern containing the zeroth and first orders. The first order reproduces the full wavefront of the light scattered from the original object and gives a 3D virtual image of the object for the light transmitted through the film and a 3D real image for the light reflected from the film. The purpose of this experiment is to investigate the properties of holograms by 1) making a transmission hologram of actual objects and observing its optical characteristics, and 2) making a diffraction grating by combining two beams of light in order to examine the holographic process in its simplest form.

Basic Sensitometry and Characteristics of Film Basic Sensitometry and Characteristics of Film
BASIC SENSITOMETRY AND CHARACTERISTICS OF FILM BASIC SENSITOMETRY AND CHARACTERISTICS OF FILM BASIC PHOTOGRAPHIC SENSITOMETRY Sensitometry is the science behind the art of filmmaking. It is the measurement of a film’s characteristics. These measurements are expressed in numeric and chart form to convey how a film will react to the amount of light, the type of lighting, the amount of exposure, the type of developer, the amount of development, and how all these factors interact. In most cases, a cinematographer doesn’t need a great depth of technical information to use motion picture films—using the right film speed and the right process will suKce. On the other hand, having a basic understanding of film sensitometry will help you in tasks as simple as film selection to as complicated as communicating the mood of a challenging scene. THE CHARACTERISTIC CURVE At the heart of sensitometry is the characteristic curve. The characteristic curve plots the amount of exposure against the density achieved by that exposure: 3.0 2.8 2.6 2.4 Shoulder 2.2 2.0 1.8 Y Straight Line T 1.6 I S 1.4 N E D 1.2 1.0 Base-Plus-Fog or 0.8 Gross-Fog Density 0.6 Toe 0.4 0.2 0.0 3.0 2.0 1.0 0.0 1.0 2.0 LOG EXPOSURE To create a characteristic curve, we first need some densities to plot, and they come from a sensitometric tablet exposed onto the film. Commonly called a step tablet, this highly calibrated tool consists of 21 equally spaced intervals of grey. -

The Retina Reflex Guide
by mischa koning kodak.3106.net > index manuals information The Retina Reflex Guide These web-pages have been scanned and converted from a photocopy of the "Focal Press" publication "Retina Reflex Guide", 1970 edition. There may be reference to "current" and "discontinued" models. Obviously all Retina cameras are now long discontinued, but For ease of editing if nothing else, all the original text has been retained. The original book was divided into two sections, effectively an overview and a "green pages" section covering specific models in more detail. I've not bothered with a green background to these pages, but hopefully I will have included links where appropriate to the relevant text. Similarly, page-number references; as I've included each sub- section of the book on one web-page, original page number references have been linked to the new layout.

KODAK MILESTONES 1879 - Eastman Invented an Emulsion-Coating Machine Which Enabled Him to Mass- Produce Photographic Dry Plates
KODAK MILESTONES 1879 - Eastman invented an emulsion-coating machine which enabled him to mass- produce photographic dry plates. 1880 - Eastman began commercial production of dry plates in a rented loft of a building in Rochester, N.Y. 1881 - In January, Eastman and Henry A. Strong (a family friend and buggy-whip manufacturer) formed a partnership known as the Eastman Dry Plate Company. ♦ In September, Eastman quit his job as a bank clerk to devote his full time to the business. 1883 - The Eastman Dry Plate Company completed transfer of operations to a four- story building at what is now 343 State Street, Rochester, NY, the company's worldwide headquarters. 1884 - The business was changed from a partnership to a $200,000 corporation with 14 shareowners when the Eastman Dry Plate and Film Company was formed. ♦ EASTMAN Negative Paper was introduced. ♦ Eastman and William H. Walker, an associate, invented a roll holder for negative papers. 1885 - EASTMAN American Film was introduced - the first transparent photographic "film" as we know it today. ♦ The company opened a wholesale office in London, England. 1886 - George Eastman became one of the first American industrialists to employ a full- time research scientist to aid in the commercialization of a flexible, transparent film base. 1888 - The name "Kodak" was born and the KODAK camera was placed on the market, with the slogan, "You press the button - we do the rest." This was the birth of snapshot photography, as millions of amateur picture-takers know it today. 1889 - The first commercial transparent roll film, perfected by Eastman and his research chemist, was put on the market. -

Yet we know that the first attempts at reproducing color chemically were made by Prof. T. J. Seebeck of Jena who in 1810, long before photography had even been discovered, observed that if moistened silver chloride were allowed to darken on paper and then exposed to different colors of light, the silver chloride would approximate the colors that had effected it. -
A Chronicle of the Motion Picture Industry a Chronicle of the Motion Picture Industry
A CHRONICLE OF THE MOTION PICTURE INDUSTRY A CHRONICLE OF THE MOTION PICTURE INDUSTRY INTRODUCTION If you’ve ever taken a still photograph, you’re already acquainted with the essentials of shooting a motion picture image. The biggest diMerence between the two is that the movie camera typically captures twenty-four images each second. Well into the late Nineteenth Century, most images were captured on sensitized glass plates, metal, or heavy paper. Shortly after the invention of 1951 KODAK BROWNIE photography, attempts were already underway to capture and reproduce a Movie Camera moving image. Typically, an array of individual cameras, triggered in rapid succession, captured a series of single exposures on glass plates. These experiments relied on a persistence of vision concept—the eye-brain combination is capable of melding a series of sequential images into a movie. A more practical photographic system had yet to be created. It was George Eastman’s invention of the KODAK Camera, and the flexible film it exposed, that made the movie camera possible. A HISTORY OF CINEMATOGRAPHY Human fascination with the concept of communicating with light and shadows has its roots in antiquity. Aristotle supplied the earliest reference to the camera obscura—sunlight, passing through a small hole, projected an inverted image on the wall of a darkened room. Renaissance artists traced that projected image to create accurate drawings. Gemma Frisius published a drawing of a camera obscura in 1545. Thirteen years later Giovanni Battista della Porta wrote "Magia Naturalis," a book describing the use of a camera obscura with lenses and concave mirrors to project a tableau in a darkened room.
