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 camera obscura is a darkened room with a small hole or lens at one side through which an image is projected onto a wall or table opposite the hole. The image of lensless camera obscuras is also referred to as "pinhole image".
A camera is an optical instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century.
Special effects are illusions or visual tricks used in the theatre, film, television, video game, amusement park and simulator industries to simulate the imagined events in a story or virtual world.
The following list comprises significant milestones in the development of photography technology.
A pinhole camera is a simple camera without a lens but with a tiny aperture —effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect. The size of the images depends on the distance between the object and the pinhole.
In photography, exposure is the amount of light per unit area reaching a frame of photographic film or the surface of an electronic image sensor. It is determined by shutter speed, lens F-number, and scene luminance. Exposure is measured in units of lux-seconds, and can be computed from exposure value (EV) and scene luminance in a specified region.
Cinematography is the art of motion picture photography.
Visual effects is the process by which imagery is created or manipulated outside the context of a live-action shot in filmmaking and video production. The integration of live-action footage and other live-action footage or CGI elements to create realistic imagery is called VFX.
Alton is a market town and civil parish in the East Hampshire district of Hampshire, England, near the source of the River Wey. It had a population of 17,816 at the 2011 census.
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.
An enlarger is a specialized transparency projector used to produce photographic prints from film or glass negatives, or from transparencies.
Compositing is the process or technique of combining visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene. Live-action shooting for compositing is variously called "chroma key", "blue screen", "green screen" and other names. Today, most, though not all, compositing is achieved through digital image manipulation. Pre-digital compositing techniques, however, go back as far as the trick films of Georges Méliès in the late 19th century, and some are still in use.
John Alton, born Johann Jacob Altmann, in Sopron, Kingdom of Hungary, was an American cinematographer of Hungarian-German origin. Alton photographed some of the most famous films noir of the classic period and won an Academy Award for the cinematography of An American in Paris (1951), becoming the first Hungarian-born person to do so in the cinematography category.
The Piasa or Piasa Bird is a creature from Native American mythology depicted in one of two murals painted by Native Americans on cliffsides above the Mississippi River. Its original location was at the end of a chain of limestone bluffs in Madison County, Illinois, at present-day Alton, Illinois. The original Piasa illustration no longer exists; a newer 20th-century version, based partly on 19th-century sketches and lithographs, has been placed on a bluff in Alton, Illinois, several hundred yards upstream from its origin. The limestone rock quality is unsuited for holding an image, and the painting must be regularly restored. The original site of the painting was on lithographic limestone, which was quarried away in the late 1870s by the Mississippi Lime Company.
The history of photography began with the discovery of two critical principles: camera obscura image projection and the observation that some substances are visibly altered by exposure to light. There are no artifacts or descriptions that indicate any attempt to capture images with light sensitive materials prior to the 18th century.
Light painting, painting with light,light drawing, or light art performance photography are terms that describe photographic techniques of moving a light source while taking a long-exposure photograph, either to illuminate a subject or space, or to shine light at the camera to 'draw', or by moving the camera itself during exposure of light sources. Practiced since the 1880s, the technique is used for both scientific and artistic purposes, as well as in commercial photography.
Bentworth and Lasham railway station in Hampshire, England was on the Basingstoke and Alton Light Railway between the villages of Bentworth to the south and Lasham to the north.
Landscape photography shows the spaces within the world, sometimes vast and unending, but other times microscopic. Landscape photographs typically capture the presence of nature but can also focus on human-made features or disturbances of landscapes. Landscape photography is done for a variety of reasons. Perhaps the most common is to recall a personal observation or experience while in the outdoors, especially when traveling. Others pursue it particularly as an outdoor lifestyle, to be involved with nature and the elements, some as an escape from the artificial world.
