  • Digital Holography Using a Laser Pointer and Consumer Digital Camera Report Date: June 22Nd, 2004
    Digital Holography using a Laser Pointer and Consumer Digital Camera Report date: June 22nd, 2004 by David Garber, M.E. undergraduate, Johns Hopkins University, [email protected] Available online at http://pegasus.me.jhu.edu/~lefd/shc/LPholo/lphindex.htm Acknowledgements Faculty sponsor: Prof. Joseph Katz, [email protected] Project idea and direction: Dr. Edwin Malkiel, [email protected] Digital holography reconstruction: Jian Sheng, [email protected] Abstract The point of this project was to examine the feasibility of low-cost holography. Can viable holograms be recorded using an ordinary diode laser pointer and a consumer digital camera? How much does it cost? What are the major difficulties? I set up an in-line holographic system and recorded both still images and movies using a $600 Fujifilm Finepix S602Z digital camera and a $10 laser pointer by Lazerpro. Reconstruction of the stills shows clearly that successful holograms can be created with a low-cost optical setup. The movies did not reconstruct, due to compression and very low image resolution. Garber 2 Theoretical Background What is a hologram? The Merriam-Webster dictionary defines a hologram as, “a three-dimensional image reproduced from a pattern of interference produced by a split coherent beam of radiation (as a laser).” Holograms can produce a three-dimensional image, but it is more helpful for our purposes to think of a hologram as a photograph that can be refocused at any depth. So while a photograph taken of two people standing far apart would have one in focus and one blurry, a hologram taken of the same scene could be reconstructed to bring either person into focus.

  • Statement by the Association of Hoving Image Archivists (AXIA) To
    Statement by the Association of Hoving Image Archivists (AXIA) to the National FTeservation Board, in reference to the Uational Pilm Preservation Act of 1992, submitted by Dr. Jan-Christopher Eorak , h-esident The Association of Moving Image Archivists was founded in November 1991 in New York by representatives of over eighty American and Canadian film and television archives. Previously grouped loosely together in an ad hoc organization, Pilm Archives Advisory Committee/Television Archives Advisory Committee (FAAC/TAAC), it was felt that the field had matured sufficiently to create a national organization to pursue the interests of its constituents. According to the recently drafted by-laws of the Association, AHIA is a non-profit corporation, chartered under the laws of California, to provide a means for cooperation among individuals concerned with the collection, preservation, exhibition and use of moving image materials, whether chemical or electronic. The objectives of the Association are: a.) To provide a regular means of exchanging information, ideas, and assistance in moving image preservation. b.) To take responsible positions on archival matters affecting moving images. c.) To encourage public awareness of and interest in the preservation, and use of film and video as an important educational, historical, and cultural resource. d.) To promote moving image archival activities, especially preservation, through such means as meetings, workshops, publications, and direct assistance. e. To promote professional standards and practices for moving image archival materials. f. To stimulate and facilitate research on archival matters affecting moving images. Given these objectives, the Association applauds the efforts of the National Film Preservation Board, Library of Congress, to hold public hearings on the current state of film prese~ationin 2 the United States, as a necessary step in implementing the National Film Preservation Act of 1992.

  • Session Outline: History of the Daguerreotype
    Fundamentals of the Conservation of Photographs SESSION: History of the Daguerreotype INSTRUCTOR: Grant B. Romer SESSION OUTLINE ABSTRACT The daguerreotype process evolved out of the collaboration of Louis Jacques Mande Daguerre (1787- 1851) and Nicephore Niepce, which began in 1827. During their experiments to invent a commercially viable system of photography a number of photographic processes were evolved which contributed elements that led to the daguerreotype. Following Niepce’s death in 1833, Daguerre continued experimentation and discovered in 1835 the basic principle of the process. Later, investigation of the process by prominent scientists led to important understandings and improvements. By 1843 the process had reached technical perfection and remained the commercially dominant system of photography in the world until the mid-1850’s. The image quality of the fine daguerreotype set the photographic standard and the photographic industry was established around it. The standardized daguerreotype process after 1843 entailed seven essential steps: plate polishing, sensitization, camera exposure, development, fixation, gilding, and drying. The daguerreotype process is explored more fully in the Technical Note: Daguerreotype. The daguerreotype image is seen as a positive to full effect through a combination of the reflection the plate surface and the scattering of light by the imaging particles. Housings exist in great variety of style, usually following the fashion of miniature portrait presentation. The daguerreotype plate is extremely vulnerable to mechanical damage and the deteriorating influences of atmospheric pollutants. Hence, highly colored and obscuring corrosion films are commonly found on daguerreotypes. Many daguerreotypes have been damaged or destroyed by uninformed attempts to wipe these films away.

  • Digital Camera Functions All Photography Is Based on the Same
    Digital Camera Functions All photography is based on the same optical principle of viewing objects with our eyes. In both cases, light is reflected off of an object and passes through a lens, which focuses the light rays, onto the light sensitive retina, in the case of eyesight, or onto film or an image sensor the case of traditional or digital photography. The shutter is a curtain that is placed between the lens and the camera that briefly opens to let light hit the film in conventional photography or the image sensor in digital photography. The shutter speed refers to how long the curtain stays open to let light in. The higher the number, the shorter the time, and consequently, the less light gets in. So, a shutter speed of 1/60th of a second lets in half the amount of light than a speed of 1/30th of a second. For most normal pictures, shutter speeds range from 1/30th of a second to 1/100th of a second. A faster shutter speed, such as 1/500th of a second or 1/1000th of a second, would be used to take a picture of a fast moving object such as a race car; while a slow shutter speed would be used to take pictures in low-light situations, such as when taking pictures of the moon at night. Remember that the longer the shutter stays open, the more chance the image will be blurred because a person cannot usually hold a camera still for very long. A tripod or other support mechanism should almost always be used to stabilize the camera when slow shutter speeds are used.

  • Affective Strategies in Novels of the Spanish
    Dr Stuart Davis, Girton College, Cambridge Reading beyond Cognitive Meaning: Affective Strategies in Novels of the Spanish “Memory Boom” The twenty-first century “memory boom” in Spain has resulted in a plethora of writing and fictions in which the civil war and the early years of Franco’s dictatorship feature prominently. Studies of these works have addressed representations of memory and trauma, recognizing how the authors reanimate the past and narrate stories of conflict and loss to a readership, distanced from the historical events. This essay explores four texts, identifying the strategies that have shaped their circulation in the current affective economy. Analysis pays particular attention to text, but also explores the image as formative in the reading experience. Durante el "boom de la memoria" del siglo XXI en España se han publicado una gran cantidad de libros y ficciones que han utilizado como fondo narrativo la guerra civil o los primeros años de la dictadura franquista. Los análisis de estas obras han abordado sus representaciones de las memorias y el trauma, reconociendo la tarea de los autores en recrear el pasado y en narrar a los lectores, lejanos de los acontecimientos históricos, historias del conflicto y de las pérdidas personales. Este trabajo examina cuatro textos, identificando las estrategias que han influido su circulación en una economía afectiva actual. El análisis presta atención al texto, pero también explora como la imagen informa la lectura de estas historias. During the recent “memory boom” of writing concerning the Spanish civil war and Francoist dictatorship many books have been sold and critical ink spilt as we examine the nature of the representation of the period, the recovery of memory and the ongoing need to engage with the trauma and repression of recent Spanish historical events.

  • Sample Manuscript Showing Specifications and Style
    Information capacity: a measure of potential image quality of a digital camera Frédéric Cao 1, Frédéric Guichard, Hervé Hornung DxO Labs, 3 rue Nationale, 92100 Boulogne Billancourt, FRANCE ABSTRACT The aim of the paper is to define an objective measurement for evaluating the performance of a digital camera. The challenge is to mix different flaws involving geometry (as distortion or lateral chromatic aberrations), light (as luminance and color shading), or statistical phenomena (as noise). We introduce the concept of information capacity that accounts for all the main defects than can be observed in digital images, and that can be due either to the optics or to the sensor. The information capacity describes the potential of the camera to produce good images. In particular, digital processing can correct some flaws (like distortion). Our definition of information takes possible correction into account and the fact that processing can neither retrieve lost information nor create some. This paper extends some of our previous work where the information capacity was only defined for RAW sensors. The concept is extended for cameras with optical defects as distortion, lateral and longitudinal chromatic aberration or lens shading. Keywords: digital photography, image quality evaluation, optical aberration, information capacity, camera performance database 1. INTRODUCTION The evaluation of a digital camera is a key factor for customers, whether they are vendors or final customers. It relies on many different factors as the presence or not of some functionalities, ergonomic, price, or image quality. Each separate criterion is itself quite complex to evaluate, and depends on many different factors. The case of image quality is a good illustration of this topic.

    Juan E. De Castro. Mario Vargas Llosa. Public Intellectual in Neoliberal Latin America. Tucson: University of Arizona Press, 2011. Print. 179 Pp. ──────────────────────────────── CARLOS AGUIRRE UNIVERSITY OF OREGON Mario Vargas Llosa, one of Latin America’s most important writers and intellectuals and the recipient of, among numerous other awards, the 2010 Nobel Prize in literature, is not only the author of an admirable corpus of novels, theater plays, and essays on literary criticism, but also somebody that has been at the center on countless political and literary controversies ever since he came into the literary and political spotlight in 1962 when he won the Biblioteca Breve award for his novel Time of the Hero at the age of twenty-six: the novel was received with great hostility in his home country, Peru, where prominent members of the military accused him of being a Communist and a traitor; in 1967, when he won the Rómulo Gallegos prize for his novel The Green House, he engaged in a dispute (at that time private) with Cuban officials such as Haydeé Santamaría who allegedly wanted him to make a fake donation of the cash prize to Che Guevara’s guerrilla movements; in 1971, he publicly and loudly denounced the Cuban government after the imprisonment and public recounting of Heberto Padilla and other writers accused of counter-revolutionary activities; in 1974, he criticized the confiscation of media in Peru by a military regime that he had hitherto supported and became the subject of a fierce polemic in his country; in 1976, he was

  • Lab 11: the Compound Microscope
    OPTI 202L - Geometrical and Instrumental Optics Lab 9-1 LAB 9: THE COMPOUND MICROSCOPE The microscope is a widely used optical instrument. In its simplest form, it consists of two lenses Fig. 9.1. An objective forms a real inverted image of an object, which is a finite distance in front of the lens. This image in turn becomes the object for the ocular, or eyepiece. The eyepiece forms the final image which is virtual, and magnified. The overall magnification is the product of the individual magnifications of the objective and the eyepiece. Figure 9.1. Images in a compound microscope. To illustrate the concept, use a 38 mm focal length lens (KPX079) as the objective, and a 50 mm focal length lens (KBX052) as the eyepiece. Set them up on the optical rail and adjust them until you see an inverted and magnified image of an illuminated object. Note the intermediate real image by inserting a piece of paper between the lenses. Q1 ● Can you demonstrate the final image by holding a piece of paper behind the eyepiece? Why or why not? The eyepiece functions as a magnifying glass, or simple magnifier. In effect, your eye looks into the eyepiece, and in turn the eyepiece looks into the optical system--be it a compound microscope, a spotting scope, telescope, or binocular. In all cases, the eyepiece doesn't view an actual object, but rather some intermediate image formed by the "front" part of the optical system. With telescopes, this intermediate image may be real or virtual. With the compound microscope, this intermediate image is real, formed by the objective lens.

The field of digital images compression becomes an important field of digital images processing fields due to the need to exploit the available storage space as much as possible and reduce the time required to transmit the image. Baseline JPEG Standard technique is used in compression of images with 8-bit color depth. Basically, this scheme consists of seven operations which are the sampling, the partitioning, the transform, the quantization, the entropy coding and Huffman coding. First, the sampling process is used to reduce the size of the image and the number bits required to represent it. Next, the partitioning process is applied to the image to get (8×8) image block. Then, the discrete cosine transform is used to transform the image block data from spatial domain to frequency domain to make the data easy to process.

Paper prepared in cooperation with the Pacific Northwest Region. Abstract Hall, Frederick C. 2001 Ground-based photographic monitoring. Gen. Tech. Rep. PNW-GTR-503. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 340 p. Land management professionals (foresters, wildlife biologists, range managers, and land managers such as ranchers and forest land owners) often have need to evaluate their management activities. Photographic monitoring is a fast, simple, and effective way to determine if changes made to an area have been successful. Ground-based photo monitoring means using photographs taken at a specific site to monitor conditions or change. It may be divided into two systems: (1) comparison photos, whereby a photograph is used to compare a known condition with field conditions to estimate some parameter of the field condition; and (2) repeat photo- graphs, whereby several pictures are taken of the same tract of ground over time to detect change. Comparison systems deal with fuel loading, herbage utilization, and public reaction to scenery. Repeat photography is discussed in relation to land- scape, remote, and site-specific systems. Critical attributes of repeat photography are (1) maps to find the sampling location and of the photo monitoring layout; (2) documentation of the monitoring system to include purpose, camera and film, w e a t h e r, season, sampling technique, and equipment; and (3) precise replication of photographs.
