  • “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.

It has been accepted for inclusion in Dissertations - ALL by an authorized administrator of SURFACE. For more information, please contact [email protected]. ABSTRACT This study examines the perceived credibility of professional photojournalism in context to the usage of User-Generated Content (UGC) when compared across digital news and social media platforms, by individual news consumers in the United States employing a Q methodology experiment. The literature review studies source credibility as the theoretical framework through which to begin; however, using an inductive design, the data may indicate additional patterns and themes. Credibility as a news concept has been studied in terms of print media, broadcast and cable television, social media, and inline news, both individually and between genres. Very few studies involve audience perceptions of credibility, and even fewer are concerned with visual images. Using online Q methodology software, this experiment was given to 100 random participants who sorted a total of 40 images labeled with photographer and platform information. The data revealed that audiences do discern the source of the image, in both the platform and the photographer, but also take into consideration the category of news image in their perception of the credibility of an image.

  • 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.

  • 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.

  • HASSELBLAD INTRODUCES the H6D-400C MS, a 400 MEGA PIXEL
    Press information – for immediate release Gothenburg, Sweden 16 Jan 2018 HASSELBLAD INTRODUCES THE H6D-400c MS, A 400 MEGA PIXEL MULTI-SHOT CAMERA Building on a vast experience of developing exceptional, high-quality single and multi-shot cameras, Hasselblad once again has raised the bar for image quality captured with medium format system. Multi-Shot capture has become an industry standard in the field of art reproduction and cultural heritage for the documentation of paintings, sculptures, and artwork. As the only professional medium format system to feature multi-shot technology, Hasselblad continues to be the leading choice for institutions, organizations, and museums worldwide to record historic treasures in the highest image quality possible. With over 10 years of digital imaging expertise, the latest Multi-Shot digital camera combines the H6D’s unrivalled ease of use with a completely new frontier of image quality and detail. This new camera encompasses all of the technological functions of Hasselblad’s H6D single shot camera, and adds to that the resolution and colour fidelity advancements that only Multi-Shot photography can bring to image capture. With an effective resolution of 400MP via 6 shot image capture, or 100MP resolution in either 4 shot Multi-Shot capture or single shot mode, the Multi-Shot capture requires the sensor and its mount to be moved at a high-precision of 1 or ½ a pixel at a time via a piezo unit. To capture Multi-Shot images the camera must be tethered to a PC or MAC. In 400MP Multi-Shot mode, 6 images are captured, the first 4 involve moving the sensor by one pixel at a time to achieve real colour data (GRGB- see 4 shot diagrams below), this cycle then returns the sensor to its starting point.

  • 1.1 Introduction to the Digital Systems
    1.1 Introduction to the digital systems PHO 130 F Digital Photography Prof. Lorenzo Guasti How a DSLR work and why we call a camera “reflex” The heart of all digital cameras is of course the digital imaging sensor. It is the component that converts the light coming from the subject you are photographing into an electronic signal, and ultimately into the digital photograph that you can view or print PHO 130 F Digital Photography Prof. Lorenzo Guasti Although they all perform the same task and operate in broadly the same way, there are in fact th- ree different types of sensor in common use today. The first one is the CCD, or Charge Coupled Device. CCDs have been around since the 1960s, and have become very advanced, however they can be slower to operate than other types of sensor. The main alternative to CCD is the CMOS, or Complimentary Metal-Oxide Semiconductor sen- sor. The main proponent of this technology being Canon, which uses it in its EOS range of digital SLR cameras. CMOS sensors have some of the signal processing transistors mounted alongside the sensor cell, so they operate more quickly and can be cheaper to make. A third but less common type of sensor is the revolutionary Foveon X3, which offers a number of advantages over conventional sensors but is so far only found in Sigma’s range of digital SLRs and its forthcoming DP1 compact camera. I’ll explain the X3 sensor after I’ve explained how the other two types work. PHO 130 F Digital Photography Prof.
