“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. -
Depth-Aware Blending of Smoothed Images for Bokeh Effect Generation
1 Depth-aware Blending of Smoothed Images for Bokeh Effect Generation Saikat Duttaa,∗∗ aIndian Institute of Technology Madras, Chennai, PIN-600036, India ABSTRACT Bokeh effect is used in photography to capture images where the closer objects look sharp and every- thing else stays out-of-focus. Bokeh photos are generally captured using Single Lens Reflex cameras using shallow depth-of-field. Most of the modern smartphones can take bokeh images by leveraging dual rear cameras or a good auto-focus hardware. However, for smartphones with single-rear camera without a good auto-focus hardware, we have to rely on software to generate bokeh images. This kind of system is also useful to generate bokeh effect in already captured images. In this paper, an end-to-end deep learning framework is proposed to generate high-quality bokeh effect from images. The original image and different versions of smoothed images are blended to generate Bokeh effect with the help of a monocular depth estimation network. The proposed approach is compared against a saliency detection based baseline and a number of approaches proposed in AIM 2019 Challenge on Bokeh Effect Synthesis. Extensive experiments are shown in order to understand different parts of the proposed algorithm. The network is lightweight and can process an HD image in 0.03 seconds. This approach ranked second in AIM 2019 Bokeh effect challenge-Perceptual Track. 1. Introduction tant problem in Computer Vision and has gained attention re- cently.

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. -
DEPTH of FIELD CHEAT SHEET What Is Depth of Field? the Depth of Field (DOF) Is the Area of a Scene That Appears Sharp in the Image
Ms. Brown Photography One DEPTH OF FIELD CHEAT SHEET What is Depth of Field? The depth of field (DOF) is the area of a scene that appears sharp in the image. DOF refers to the zone of focus in a photograph or the distance between the closest and furthest parts of the picture that are reasonably sharp. Depth of field is determined by three main attributes: 1) The APERTURE (size of the opening) 2) The SHUTTER SPEED (time of the exposure) 3) DISTANCE from the subject being photographed 4) SHALLOW and GREAT Depth of Field Explained Shallow Depth of Field: In shallow depth of field, the main subject is emphasized by making all other elements out of focus. (Foreground or background is purposely blurry) Aperture: The larger the aperture, the shallower the depth of field. Distance: The closer you are to the subject matter, the shallower the depth of field. ***You cannot achieve shallow depth of field with excessive bright light. This means no bright sunlight pictures for shallow depth of field because you can’t open the aperture wide enough in bright light.*** SHALLOW DOF STEPS: 1. Set your camera to a small f/stop number such as f/2-f/5.6. 2. GET CLOSE to your subject (between 2-5 feet away). 3. Don’t put the subject too close to its background; the farther away the subject is from its background the better. 4. Set your camera for the correct exposure by adjusting only the shutter speed (aperture is already set). 5. Find the best composition, focus the lens of your camera and take your picture. -
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. -

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. -

The main themes of the symposium were comparison of classical perimetry with visual evoked response, comparison of classical perimetry with special psychophysi- cal methods, and optic nerve pathology. Understandably many papers dealt with computer assisted perimetry. This rapidly developing subgroup of peri- metry may radically change the future of our method of examination. New instruments were introduced, new and exciting software was proposed and the results of comparative investigations reported. -

Dof 4.0 – a Depth of Field Calculator
DoF 4.0 – A Depth of Field Calculator Last updated: 8-Mar-2021 Introduction When you focus a camera lens at some distance and take a photograph, the further subjects are from the focus point, the blurrier they look. Depth of field is the range of subject distances that are acceptably sharp. It varies with aperture and focal length, distance at which the lens is focused, and the circle of confusion – a measure of how much blurring is acceptable in a sharp image. The tricky part is defining what acceptable means. Sharpness is not an inherent quality as it depends heavily on the magnification at which an image is viewed. When viewed from the same distance, a smaller version of the same image will look sharper than a larger one. Similarly, an image that looks sharp as a 4x6" print may look decidedly less so at 16x20". All other things being equal, the range of in-focus distances increases with shorter lens focal lengths, smaller apertures, the farther away you focus, and the larger the circle of confusion. Conversely, longer lenses, wider apertures, closer focus, and a smaller circle of confusion make for a narrower depth of field. Sometimes focus blur is undesirable, and sometimes it’s an intentional creative choice. Either way, you need to understand depth of field to achieve predictable results. What is DoF? DoF is an advanced depth of field calculator available for both Windows and Android. What DoF Does Even if your camera has a depth of field preview button, the viewfinder image is just too small to judge critical sharpness.
