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. -

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. -
The History of Photography and the Camera
The History of Photography and the Camera: From Pinhole to SmartPhones Whether you're hanging out with friends on the beach or reading about the history of the 1930s, photography will likely make an appearance. The oldest known photograph dates back to 1826, but the structure that would become the first camera was described by Aristotle. The process of taking pictures has become increasingly refined during the 19th century, transitioning from heavy glass plates to light, gelatin-coated flexible film. Today, once-innovative film cameras take a back seat to the convenience and ease of digital cameras. Pinhole Cameras and Photography The pinhole camera (also known as a camera obscura) was first envisioned around the 5th century BCE. The camera obscura was a box with a small hole in it, through which light (and the image carried by it) would travel and reflect against a mirror. The camera obscura was originally used to observe solar events and to aid in drawing architecture, though it became something entirely new in 1800. A young man named Thomas Wedgwood attempted to capture the image portrayed in a camera obscura with silver nitrate, which is light-sensitive. Unfortunately, the images didn't hold, and it wasn't until the French inventor Joseph Niépce attempted the same feat with bitumen (a kind of tar) that the first photograph was produced.

The Essential Reference Guide for Filmmakers
THE ESSENTIAL REFERENCE GUIDE FOR FILMMAKERS IDEAS AND TECHNOLOGY IDEAS AND TECHNOLOGY AN INTRODUCTION TO THE ESSENTIAL REFERENCE GUIDE FOR FILMMAKERS Good films—those that e1ectively communicate the desired message—are the result of an almost magical blend of ideas and technological ingredients. And with an understanding of the tools and techniques available to the filmmaker, you can truly realize your vision. The “idea” ingredient is well documented, for beginner and professional alike. Books covering virtually all aspects of the aesthetics and mechanics of filmmaking abound—how to choose an appropriate film style, the importance of sound, how to write an e1ective film script, the basic elements of visual continuity, etc. Although equally important, becoming fluent with the technological aspects of filmmaking can be intimidating. With that in mind, we have produced this book, The Essential Reference Guide for Filmmakers. In it you will find technical information—about light meters, cameras, light, film selection, postproduction, and workflows—in an easy-to-read- and-apply format. Ours is a business that’s more than 100 years old, and from the beginning, Kodak has recognized that cinema is a form of artistic expression. Today’s cinematographers have at their disposal a variety of tools to assist them in manipulating and fine-tuning their images. And with all the changes taking place in film, digital, and hybrid technologies, you are involved with the entertainment industry at one of its most dynamic times. As you enter the exciting world of cinematography, remember that Kodak is an absolute treasure trove of information, and we are here to assist you in your journey. -

Glaeser Lawrence Berkeley National Laboratory University of California, Berkeley Berkeley, CA 94720 Phone: 510-642-2905 Fax: 510-486-6488 1 ABSTRACT A film-handling machine (robot) has been built which can, in conjunction with a commercially available film densitometer, exchange and digitize over 300 electron micrographs per day. Implementation of robotic film handling effectively eliminates the delay and tedium associated with digitizing images when data are initially recorded on photographic film. The modulation transfer function (MTF) of the commercially available densitometer is significantly worse than that of a high-end, scientific microdensitometer. Nevertheless, its signal-to-noise ratio (S/N) is quite excellent, allowing substantial restoration of the output to “near-to-perfect” performance. Due to the large area of the standard electron microscope film that can be digitized by the commercial densitometer (up to 10,000x13,680 pixels with an appropriately coded holder), -
