⭐ Core Definition: Photograph

A photograph (also known as a photo, or more generically referred to as an image or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor. The process and practice of creating such images is called photography.

Most photographs are now created using a smartphone or camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would perceive.

Photograph in the context of Photography

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 (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. A person who operates a camera to capture or take photographs is called a photographer, while the captured image, also known as a photograph, is the result produced by the camera.

Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

Photograph in the context of Work of art

A work of art, artwork, art piece, piece of art or art object is an artistic creation of aesthetic value. Except for "work of art", which may be used of any work regarded as art in its widest sense, including works from literature and music, these terms apply principally to tangible, physical forms of visual art:

Used more broadly, the term is less commonly applied to:

Photograph in the context of Image

An image or picture is a visual representation. An image can be two-dimensional, such as a drawing, painting, or photograph, or three-dimensional, such as a carving or sculpture. Images may be displayed through other media, including a projection on a surface, activation of electronic signals, or digital displays; they can also be reproduced through mechanical means, such as photography, printmaking, or photocopying. Images can also be animated through digital or physical processes.

In the context of signal processing, an image is a distributed amplitude of color(s). In optics, the term image (or optical image) refers specifically to the reproduction of an object formed by light waves coming from the object.

Photograph in the context of Photographic film

Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film. Film is typically segmented in frames, that give rise to separate photographs.

The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, most films are sensitive to ultraviolet light, X-rays, gamma rays, and high-energy particles. Unmodified silver halide crystals are sensitive only to the blue part of the visible spectrum, producing unnatural-looking renditions of some colored subjects. This problem was resolved with the discovery that certain dyes, called sensitizing dyes, when adsorbed onto the silver halide crystals made them respond to other colors as well. First orthochromatic (sensitive to blue and green) and finally panchromatic (sensitive to all visible colors) films were developed. Panchromatic film renders all colors in shades of gray approximately matching their subjective brightness. By similar techniques, special-purpose films can be made sensitive to the infrared (IR) region of the spectrum.

Photograph in the context of Negative (photography)

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.

In the case of color negatives, the colors are also reversed into their respective complementary colors. Typical color negatives have an overall dull orange tint due to an automatic color-masking feature that ultimately results in improved color reproduction.

Photograph in the context of Graphics

Graphics (from Ancient Greek γραφικός (التصميم) 'pertaining to drawing, painting, writing, etc.') 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.

Examples are photographs, drawings, line art, mathematical graphs, line graphs, charts, diagrams, typography, numbers, symbols, geometric designs, maps, engineering drawings, or other images. Graphics often combine text, illustration, and color. Graphic design may consist of the deliberate selection, creation, or arrangement of typography alone, as in a brochure, flyer, poster, web site, or book without any other element. The objective can be clarity or effective communication, association with other cultural elements, or merely the creation of a distinctive style.

Photograph in the context of Aerial photography

Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other airborne platforms. When taking motion pictures, it is also known as aerial videography.

Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs or "drones"), balloons, blimps and dirigibles, rockets, pigeons, kites, or using action cameras while skydiving or wingsuiting. Handheld cameras may be manually operated by the photographer, while mounted cameras are usually remotely operated or triggered automatically.

Photograph in the context of Musée Rodin

The Musée Rodin (English: Rodin Museum) of Paris, France, is an art museum that was opened in 1919, primarily dedicated to the works of the French sculptor Auguste Rodin. It has two sites: the Hôtel Biron and surrounding grounds in central Paris, as well as just outside Paris at Rodin's old home, the Villa des Brillants at Meudon, Hauts-de-Seine. The collection includes 6,600 sculptures, 8,000 drawings, 8,000 old photographs and 7,000 objets d'art. The museum receives 700,000 visitors annually.

While living in the Villa des Brillants, Rodin used the Hôtel Biron as his workshop from 1908 onwards. Hôtel Biron had been designed by the architect Jean Aubert and Rodin donated his entire collection of sculptures, along with paintings by Vincent van Gogh, Claude Monet and Pierre-Auguste Renoir he had acquired to the French State on the condition that they turn the buildings into a museum dedicated to his works. The Musée Rodin contains most of Rodin's significant creations, including The Thinker, The Kiss and The Gates of Hell. Many of his sculptures are displayed in the museum's extensive garden. The museum includes a room dedicated to the works of Camille Claudel and one of the two castings of The Mature Age.

Photograph in the context of Documentary

A documentary film (often described simply as a documentary) is a nonfiction, motion picture intended to "document reality, primarily for instruction, education or maintaining a historical record". The American author and media analyst Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries".

Research into information gathering, as a behavior, and the sharing of knowledge, as a concept, has noted how documentary movies were preceded by the notable practice of documentary photography. This has involved the use of singular photographs to detail the complex attributes of historical events and continues to a certain degree to this day, with an example being the conflict-related photography achieved by popular figures such as Mathew Brady during the American Civil War. Documentary movies evolved from the creation of singular images in order to convey particular types of information in depth, using film as a medium.

Photograph in the context of Animation

Animation is a filmmaking technique whereby still images are manipulated to create moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Animation has been recognized as an artistic medium, specifically within the entertainment industry. Many animations are either traditional animations or computer animations made with computer-generated imagery (CGI). Stop motion animation, in particular claymation, is also prominent alongside these other forms, albeit to a lesser degree.

Animation is contrasted with live action, although the two do not exist in isolation. Many filmmakers have produced films that are a hybrid of the two. As CGI increasingly approximates photographic imagery, filmmakers can relatively easily composite 3D animated visual effects (VFX) into their film, rather than using practical effects.

Photograph in the context of Mobile phone camera

A camera phone is a mobile phone that is able to capture photographs and often record video using one or more built-in digital cameras. It can also send the resulting image wirelessly and conveniently. The first commercial phone with a color camera was the Kyocera Visual Phone VP-210, released in Japan in May 1999. While cameras in mobile phones used to be supplementary, they have been a major selling point of mobile phones since the 2010s.

Most camera phones are smaller and simpler than the separate digital cameras. In the smartphone era, the steady sales increase of camera phones caused point-and-shoot camera sales to peak about 2010, and decline thereafter. The concurrent improvement of smartphone camera technology and its other multifunctional benefits have led to it gradually replacing compact point-and-shoot cameras.

Photograph in the context of Film stock

Film stock is a type of photographic film that is used for recording motion pictures or animation. It is recorded on by a movie camera, developed, edited, and projected onto a screen using a movie projector.

Photographic film consists of a long strip of transparent plastic film base, coated on one side with a photographic emulsion: a mixture of gelatin and microscopic light-sensitive silver halide crystals. A very short exposure is made, producing an invisible latent image in the emulsion, which can be chemically developed into a visible photograph.

Photograph in the context of View from the Window at Le Gras

View from the Window at Le Gras (French: Point de vue du Gras) is the oldest surviving photograph. It was created by French inventor Nicéphore Niépce sometime between 1826 and 1827 in Saint-Loup-de-Varennes, France, and shows parts of the buildings and surrounding countryside of his estate, Le Gras [fr], as seen from a high window. The image was created by heliography, a process which Niépce had invented around 1822, and which uses the hardening of bitumen in light to record an image after washing off the remaining unhardened material.
