“Digital Single Lens Reflex”
PHOTOGRAPHY GENERIC ELECTIVE SEM-II DSLR stands for “Digital Single Lens Reflex”. In simple language, a DSLR is a digital camera that uses a mirror mechanism to either reflect light from a camera lens to an optical viewfinder (which is an eyepiece on the back of the camera that one looks through to see what they are taking a picture of) or let light fully pass onto the image sensor (which captures the image) by moving the mirror out of the way. Although single lens reflex cameras have been available in various shapes and forms since the 19th century with film as the recording medium, the first commercial digital SLR with an image sensor appeared in 1991. Compared to point-and-shoot and phone cameras, DSLR cameras typically use interchangeable lenses. Take a look at the following image of an SLR cross section (image courtesy of Wikipedia): When you look through a DSLR viewfinder / eyepiece on the back of the camera, whatever you see is passed through the lens attached to the camera, which means that you could be looking at exactly what you are going to capture. Light from the scene you are attempting to capture passes through the lens into a reflex mirror (#2) that sits at a 45 degree angle inside the camera chamber, which then forwards the light vertically to an optical element called a “pentaprism” (#7). The pentaprism then converts the vertical light to horizontal by redirecting the light through two separate mirrors, right into the viewfinder (#8). When you take a picture, the reflex mirror (#2) swings upwards, blocking the vertical pathway and letting the light directly through. -
Completing a Photography Exhibit Data Tag
Completing a Photography Exhibit Data Tag Current Data Tags are available at: https://unl.box.com/s/1ttnemphrd4szykl5t9xm1ofiezi86js Camera Make & Model: Indicate the brand and model of the camera, such as Google Pixel 2, Nikon Coolpix B500, or Canon EOS Rebel T7. Focus Type: • Fixed Focus means the photographer is not able to adjust the focal point. These cameras tend to have a large depth of field. This might include basic disposable cameras. • Auto Focus means the camera automatically adjusts the optics in the lens to bring the subject into focus. The camera typically selects what to focus on. However, the photographer may also be able to select the focal point using a touch screen for example, but the camera will automatically adjust the lens. This might include digital cameras and mobile device cameras, such as phones and tablets. • Manual Focus allows the photographer to manually adjust and control the lens’ focus by hand, usually by turning the focus ring. Camera Type: Indicate whether the camera is digital or film. (The following Questions are for Unit 2 and 3 exhibitors only.) Did you manually adjust the aperture, shutter speed, or ISO? Indicate whether you adjusted these settings to capture the photo. Note: Regardless of whether or not you adjusted these settings manually, you must still identify the images specific F Stop, Shutter Sped, ISO, and Focal Length settings. “Auto” is not an acceptable answer. Digital cameras automatically record this information for each photo captured. This information, referred to as Metadata, is attached to the image file and goes with it when the image is downloaded to a computer for example. -
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. -

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. -

Carl Zeiss, 32, Wagnergasse, Jena, Germany. ((1847) also: 29/II Dorotheen strasse 29, Berlin, Germany. (1901) and 29, Margaret St, Regent St, London W (1901) The founder, Carl Zeiss (1816-1888) was born in Weimar, the son of a cabinet maker and ivory carver. He graduated from school in 1834, qualified to be apprenticed to the Grand Dukes Instrument maker, Dr Koerner, and attended academic courses as well as working as apprentice. Next he travelled from Jan. 1838 to Oct. 1845 to study in Stuttgart, Darmstadt, Vienna, and Berlin to broaden his experience. Back at home, he studied chemistry and higher mathematics. By May 1845, he felt well enough qualified to apply to the County Administration at Weimar for permission to found "An establishment for the production of advanced mechanical devices", hoping for a relationship with the University to advance designs. Money was tight with capital of 100 Thalers (possibly £100) only, but in Nov. 1846, he opened at 7, Neugasse. It remained a small business for years, as it took some 20 years for the University relationship to be productive, and he often grew weary of the trial and error methods traditionally used in the trade. Much of the production was of microscopes- often relatively simple ones by modern standards, such as dissection viewers. Then in 1863, a young lecturer Ernst Abbe (1840-1905) joined the University to teach physics and astronomy. Zeiss approached him in 1866 for cooperation in the design of improved systems and this lead to new ideas, eg in the Abbe refractometer (1869), a comparator and a spectrometer. -

Hall Author Frederick C. Hall is senior plant ecologist, U.S. Department of Agriculture, Forest Service, Pacific Northwest Region, Natural Resources, P.O. Box 3623, Portland, Oregon 97208-3623. 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. -
