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. -
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. -
The Microscope Parts And
The Microscope Parts and Use Name:_______________________ Period:______ Historians credit the invention of the compound microscope to the Dutch spectacle maker, Zacharias Janssen, around the year 1590. The compound microscope uses lenses and light to enlarge the image and is also called an optical or light microscope (vs./ an electron microscope). The simplest optical microscope is the magnifying glass and is good to about ten times (10X) magnification. The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object. Before purchasing or using a microscope, it is important to know the functions of each part. Eyepiece Lens: the lens at the top that you look through. They are usually 10X or 15X power. Tube: Connects the eyepiece to the objective lenses Arm: Supports the tube and connects it to the base. It is used along with the base to carry the microscope Base: The bottom of the microscope, used for support Illuminator: A steady light source (110 volts) used in place of a mirror. Stage: The flat platform where you place your slides. Stage clips hold the slides in place. Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power. Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4X, 10X, 40X and 100X powers. When coupled with a 10X (most common) eyepiece lens, we get total magnifications of 40X (4X times 10X), 100X , 400X and 1000X. -
How Do the Lenses in a Microscope Work?
Student Name: _____________________________ Date: _________________ How do the lenses in a microscope work? Compound Light Microscope: A compound light microscope uses light to transmit an image to your eye. Compound deals with the microscope having more than one lens. Microscope is the combination of two words; "micro" meaning small and "scope" meaning view. Early microscopes, like Leeuwenhoek's, were called simple because they only had one lens. Simple scopes work like magnifying glasses that you have seen and/or used. These early microscopes had limitations to the amount of magnification no matter how they were constructed. The creation of the compound microscope by the Janssens helped to advance the field of microbiology light years ahead of where it had been only just a few years earlier. The Janssens added a second lens to magnify the image of the primary (or first) lens. Simple light microscopes of the past could magnify an object to 266X as in the case of Leeuwenhoek's microscope. Modern compound light microscopes, under optimal conditions, can magnify an object from 1000X to 2000X (times) the specimens original diameter. "The Compound Light Microscope."

The Reality of Illusion
Acta Univ. Sapientiae, Film and Media Studies, 1 (2009) 722 The Reality of Illusion A Transcendental Reevaluation of the Problem of Cinematic Reality Melinda Szalóky Department of Film and Media Studies, University of California (Santa Barbara, USA) email: [email protected] Abstract. The paper readdresses the parallel considerations of cinema as both access to an essential, true, objective reality and as a device of deception reproducing the fallacies of a biased and reductive human perception. The claim is that the critical consideration of cinematic mediation in these ambiguous terms stems from the traditional association of cinema with the working of mental mechanisms whose logic, it is argued, follows neatly Kant's transcendental constructivist dualist model of reason and its reality. Kant's idea that our sensible but merely phenomenal experience is produced and projected by our supersensible, transcendental synthetic activity, which `in itself' is as unrecoverable as is the world that it moulds, describes perfectly the imaginary-symbolic regime of cinematic signication, whose dual nature has been considered both as a hindrance and as a guarantee of objectivity. Throughout the paper, repeated emphasis is given to the signicance of Kant's insistence to preserve, and to make palpable through the aesthetic, a noumenal unknown, a pure and never fully assessable objectivity within an increasingly self-referential, self-serving and self-enclosed human reason. It has been this modicum of a humanly inaccessible, yet arguably intuitable `excess,' the pursuit and the promise of modern art, which an aesthetically biased lm theory and practice have sought to foreground. Joining forces with Deleuze, Lyotard, and iºek, as well as with Cocteau, Tarkovsky, Wenders, and Kie±lowski, the paper promotes the necessity of continued belief in a non-human metaphysical dimension, an outside within thought that forever eludes capture. -

Author Functions, Auteur Fictions Understanding Authorship in Conglomerate Hollywood Commerce, Culture, and Narrative
Author Functions, Auteur Fictions Understanding Authorship in Conglomerate Hollywood Commerce, Culture, and Narrative VOLUME I: ARGUMENTS Thomas James Wardak A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy The University of Sheffield Faculty of Arts and Humanities School of English Literature March 2017 i Abstract In 1990, Timothy Corrigan identified a rising trend in Hollywood film marketing wherein the director, or auteur, had become commercially galvanised as a brand icon. This thesis updates Corrigan’s treatise on the ‘commerce of auteurism’ to a specific 2017 perspective in order to dismantle the discursive mechanisms by which commodified author-brands create meaning and value in Conglomerate Hollywood’s promotional superstructure. By adopting a tripartite theoretical/industrial/textual analytical framework distinct from the humanistic and subjectivist excesses of traditional auteurism, by which conceptions of film authorship have typically been circumscribed, this thesis seeks to answer the oft- neglected question how does authorship work as it relates to the contemporary blockbuster narrative. Naturally, this necessitates a corresponding understanding of how texts work, which leads to the construction of a spectator-centric cognitive narratorial heuristic that conceptualises ‘the author’ as a hermeneutic code which may be activated when presented with sufficient ‘authorial’ signals. Of course, authorial signals do not only emanate from films but also promotional paratexts such -

Fine art photography is a complex task, one requiring tremendous attention to detail and the application of care in the selection and placement of lights and camera, selection of lenses, color management and reproduction on appropriate papers. It’s important to the graphic arts and photography fields because there is money to be made in reproducing fine art – whether it’s for sale as art, or as an illustration of art to be printed in a publication or used online. To reproduce artwork successfully, one must build a photographic environment conducive to this work, This is my successful reproduction image of Carlen’s roosters painting. and develop a work flow that allows for correct lighting, I succeeded with this image because it had a reproducible color palette, color management of the source image, and then and I was able to get the lighting to work using cross-polarized filters.
