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. -

Creative Flash Photography by John Schutt
Creative Flash Photography by John Schutt, http://schutt.net/john/ Creative Flash Photography By John Schutt, http://schutt.net/john/ I. A Flashy Primer At one time or another, we have each used a flash in photography. The primary way that a flash is used is to light a subject when the ambient light is too low to take an image. Learning how to use flash properly could take an entire workshop. That is not my purpose here. In this workshop, I want to teach you three things: how your flash works, how you can paint with a flash, and how to stop motion with a flash. On-camera Flash Modes Most modern flashes have three modes of use for a flash that is attached to a camera body: M, A, and TTL. “M” or “manual” was the first mode developed for flash. In this mode, the flash puts out a constant amount of light. The flash charges up, and when triggered, the flash shoots of a burst of light. Modern flashes allow the user to control the amount of light, usually in increments of 1/2, ¼, 1/8, etc the amount of the full flash exposure. The disadvantage to this flash mode is the complicated way that the light quantity was measured. To use “M” mode, you either had to have a flash meter to measure the light, or you needed to use guide numbers to determine distance and aperture settings. The second flash mode to be developed was the “A” or “automatic” mode. Popularized by the Vivitar 283, this flash mode frees the user from needing either a flash meter or the use of guide numbers. -

He has served as a lecturer on the law of evidence and scientific evidence at the University of Wisconsin, and is a member of the American Law Institute and the American Acad- emy of Forensic Sciences.-EmroR HISTORICAL HIGHLIGHTS Color photography, the miracle of modem science, is popularly assumed to be of recent origin. 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. -

Lens Mount and Flange Focal Distance
This is a page of data on the lens flange distance and image coverage of various stills and movie lens systems. It aims to provide information on the viability of adapting lenses from one system to another. Video/Movie format-lens coverage: [caveat: While you might suppose lenses made for a particular camera or gate/sensor size might be optimised for that system (ie so the circle of cover fits the gate, maximising the effective aperture and sharpness, and minimising light spill and lack of contrast... however it seems to be seldom the case, as lots of other factors contribute to lens design (to the point when sometimes a lens for one system is simply sold as suitable for another (eg large format lenses with M42 mounts for SLR's! and SLR lenses for half frame). Specialist lenses (most movie and specifically professional movie lenses) however do seem to adhere to good design practice, but what is optimal at any point in time has varied with film stocks and aspect ratios! ] 1932: 8mm picture area is 4.8×3.5mm (approx 4.5x3.3mm useable), aspect ratio close to 1.33 and image circle of ø5.94mm. 1965: super8 picture area is 5.79×4.01mm, aspect ratio close to 1.44 and image circle of ø7.043mm. 2011: Ultra Pan8 picture area is 10.52×3.75mm, aspect ratio 2.8 and image circle of ø11.2mm (minimum). 1923: standard 16mm picture area is 10.26×7.49mm, aspect ratio close to 1.37 and image circle of ø12.7mm. -
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.
