Photography is the art, application, and practice of creating images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing, and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. A person who makes photographs is called a photographer.
A photographer is a person who uses a camera to make photographs.
A twin-lens reflex camera (TLR) is a type of camera with two objective lenses of the same focal length. One of the lenses is the photographic objective or "taking lens", while the other is used for the viewfinder system, which is usually viewed from above at waist level.
Photojournalism is journalism that uses images to tell a news story. It usually only refers to still images, but can also refer to video used in broadcast journalism. Photojournalism is distinguished from other close branches of photography by having a rigid ethical framework which demands an honest and impartial approach that tells a story in strictly journalistic terms. Photojournalists contribute to the news media, and help communities connect with one other. They must be well-informed and knowledgeable, and are able to deliver news in a creative manner that is both informative and entertaining.
Panoramic photography is a technique of photography, using specialized equipment or software, that captures images with horizontally elongated fields of view. It is sometimes known as wide format photography. The term has also been applied to a photograph that is cropped to a relatively wide aspect ratio, like the familiar letterbox format in wide-screen video.
Graphics are visual images or designs on some surface, such as a wall, canvas, screen, paper, or stone, to inform, illustrate, or entertain. In contemporary usage, it includes a pictorial representation of data, as in design and manufacture, in typesetting and the graphic arts, and in educational and recreational software. Images that are generated by a computer are called computer graphics.
In photography, a negative is an image, usually on a strip or sheet of transparent plastic film, in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest. This reversed order occurs because the extremely light-sensitive chemicals a camera film must use to capture an image quickly enough for ordinary picture-taking are darkened, rather than bleached, by exposure to light and subsequent photographic processing.
Color photography is photography that uses media capable of capturing and reproducing colors. By contrast, black-and-white or gray-monochrome photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray.
In photography and cinematography, perspective distortion is a warping or transformation of an object and its surrounding area that differs significantly from what the object would look like with a normal focal length, due to the relative scale of nearby and distant features. Perspective distortion is determined by the relative distances at which the image is captured and viewed, and is due to the angle of view of the image being either wider or narrower than the angle of view at which the image is viewed, hence the apparent relative distances differing from what is expected. Related to this concept is axial magnification – the perceived depth of objects at a given magnification.
Street photography is photography conducted for art or inquiry that features unmediated chance encounters and random incidents within public places, usually with the aim of capturing images at a decisive or poignant moment by careful framing and timing. Although there is a difference between street and candid photography, it is usually subtle with most street photography being candid in nature and some candid photography being classifiable as street photography. Street photography does not necessitate the presence of a street or even the urban environment. Though people usually feature directly, street photography might be absent of people and can be of an object or environment where the image projects a decidedly human character in facsimile or aesthetic.
A tintype, also known as a melanotype or ferrotype, is a photograph made by creating a direct positive on a thin sheet of metal, colloquially called 'tin', coated with a dark lacquer or enamel and used as the support for the photographic emulsion. It was introduced in 1853 by Adolphe Alexandre Martin in Paris, like the daguerreotype was fourteen years before by Daguerre. The daguerreotype was established and most popular by now, though the primary competition for the tintype would have been the ambrotype, that shared the same collodion process, but on a glass support instead of metal. Both found unequivocal, if not exclusive, acceptance in North America. Tintypes enjoyed their widest use during the 1860s and 1870s, but lesser use of the medium persisted into 1930s and it has been revived as a novelty and fine art form in the 21st century. It has been described as the first "truly democratic" medium for mass portraiture.
Erotic photography is a style of art photography of an erotic, sexually suggestive or sexually provocative nature.
The term composition means "putting together". It can be thought of as the organization of the elements of art according to the principles of art. Composition can apply to any work of art, from music through writing and into photography, that is arranged using conscious thought.
Wedding photography is a specialty in photography that is primarily focused on the photography of events and activities relating to weddings. It may include other types of portrait photography of the couple before the official wedding day, such as a pre-wedding engagement session, in which the photographs are later used for the couple's wedding invitations. On the wedding day, the photographer(s) will provide portrait photography as well as documentary photography to document the different wedding events and rituals throughout the day(s).
Nature photography is a wide range of photography taken outdoors and devoted to displaying natural elements such as landscapes, wildlife, plants, and close-ups of natural scenes and textures. Nature photography tends to put a stronger emphasis on the aesthetic value of the photo than other photography genres, such as photojournalism and documentary photography.
VR photography is the interactive viewing of panoramic photographs, generally encompassing a 360-degree circle or a spherical view. The results is known as VR photograph, 360-degree photo, photo sphere, or spherical photo, as well as interactive panorama or immersive panorama.
Nude photography is the creation of any photograph which contains an image of a nude or semi-nude person, or an image suggestive of nudity. Nude photography is undertaken for a variety of purposes, including educational uses, commercial applications and artistic creations.
360 photography refers to a photographic technique by which a series of photos give the impression of an object rotating. These photos can be displayed as an interactive animation on web pages and apps, allowing a user to control the rotation of an object. The photos can also be displayed as an infinitely looping GIF or video.
Strip photography, or slit photography, is a photographic technique of capturing a two-dimensional image as a sequence of one-dimensional images over time, in contrast to a normal photo which is a single two-dimensional image at one point in time. A moving scene is recorded, over a period of time, using a camera that observes a narrow strip rather than the full field. If the subject is moving through this observed strip at constant speed, they will appear in the finished photo as a visible object. Stationary objects, like the background, will be the same the whole way across the photo and appear as stripes along the time axis; see examples on this page.
Photography in Sudan refers to both historical as well as to contemporary photographs taken in the cultural history of today's Republic of the Sudan. This includes the former territory of present-day South Sudan, as well as what was once Anglo-Egyptian Sudan, and some of the oldest photographs from the 1860s, taken during the Turkish-Egyptian rule (Turkiyya). As in other countries, the growing importance of photography for mass media like newspapers, as well as for amateur photographers has led to a wider photographic documentation and use of photographs in Sudan during the 20th century and beyond. In the 21st century, photography in Sudan has undergone important changes, mainly due to digital photography and distribution through social media and the Internet.
