Photography is the art, science, and practice of creating durable images by recording light (photons - hence, \photo\-graphy) or other electromagnetic radiation, either chemically by means of a light-sensitive material such as photographic film, or electronically by means of an image sensor. 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. The result in an electronic image sensor is an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result in a 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. Photography has many uses for business, science, manufacturing, art, recreational purposes, and mass communication.

Stereoscopy (also called stereoscopics or 3-D imaging) refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. These two-dimensional images are then combined in the brain to give the perception of 3-D depth.

Child pornography
Child pornography refers to images or films (also known as child abuse images) and, in some cases, writings depicting sexually explicit activities involving a child. Abuse of the child occurs during the sexual acts which are recorded in the production of child pornography, and several professors of psychology state that memories of the abuse are maintained as long as visual records exist, are accessed, and are "exploited perversely.

Radiography is the use of X-rays to view a non-uniformly composed material such as the human body. By using the physical properties of the ray an image can be developed which displays areas of different density and composition. A heterogeneous beam of X-rays is produced by an X-ray generator and is projected toward an object. According to the density and composition of the different areas of the object a proportion of X-rays are absorbed by the object.

Digital photography
Digital photography is a form of photography that uses an array of light sensitive sensors to capture the image focused by the lens, as opposed to an exposure on light sensitive film. The captured image is then stored as a digital file ready for digital processing (colour correction, sizing, cropping, etc. ), viewing or printing.

Camera phone
A camera phone is a mobile phone which is able to capture still photographs. Since early in the 21st century the majority of mobile phones in use are camera phones. Most camera phones are simpler than separate digital cameras. Their usual fixed focus lenses and smaller sensors limit their performance in poor lighting. Having no physical shutter, most have a long shutter lag. Some have no flash or optical zoom or tripod screw.

Reversal film
In photography, a reversal film is a type of photographic film that produces a positive image on a transparent base. The film is processed to produce transparencies or diapositives instead of negatives and prints. Reversal film is produced in various sizes, from 35 mm roll film to 8×10" sheet film. A slide is a specially mounted individual transparency intended for projection onto a screen using a slide projector. This allows the photograph to be viewed by a large audience at once.

Compositing is the combining of 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.

Glamour photography
Glamour photography is a genre of photography whereby the subjects, usually female, are portrayed in a romantic or sexually alluring way. The subjects may be fully clothed or seminude, but glamour photography stops short of deliberately arousing the viewer and being pornographic photography. Glamour photography is generally a composed image of a subject in a still position.

Color photography
"Color film" redirects here. For the motion picture equivalent, see Color motion picture film. Color photography is photography that uses media capable of representing colors, which are traditionally produced chemically during the photographic processing phase. By contrast, black-and-white (monochrome) photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray.

Fine-art photography
Fine art photography refers to photographs that are created in accordance with the creative vision of the photographer as artist. Fine art photography stands in contrast to photojournalism, which provides a visual account for news events, and commercial photography, the primary focus of which is to advertise products or services.

Photomontage is the process and result of making a composite photograph by cutting and joining a number of other photographs. The composite picture was sometimes photographed so that the final image is converted back into a seamless photographic print. A similar method, although one that does not use film, is realized today through image-editing software. This latter technique is referred to by professionals as "compositing", and in casual usage is often called "photoshopping".

Stock photography
Stock photography is the supply of photographs licensed for specific uses. It is used to fulfill the needs of creative assignments instead of hiring a photographer. Today, stock images can be presented in searchable online databases. They can be purchased and delivered online. Often, they are produced in studios using a wide variety of models posing as professionals, stereotypes, expressing stereotypical emotions and gesticulations or involving pets.

Mug shot
A mug shot, mugshot, police photograph, or booking photograph, is a photographic portrait taken after one is arrested. The purpose of the mug shot is to allow law enforcement to have a photographic record of the arrested individual to allow for identification by victims and investigators. Most mug shots are two-part, with one side-view photo, and one front-view. They may be compiled into a mug book in order to determine the identity of a criminal.

Pinhole camera
A pinhole camera is a simple camera without a lens and with a single small aperture – effectively a light-proof box with a small hole in one side. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box. The human eye in bright light acts similarly, as do cameras using small apertures. Up to a certain point, the smaller the hole, the sharper the image, but the dimmer the projected image.

Fashion photography
Fashion photography has been in existence since 1839. There was always the existence of fashionable dress, but the idea of taking photographs to help sell clothing and accessories had just come into play. Fashion photography is a genre of photography devoted to displaying clothing and other fashion items. Fashion photography is most often conducted for advertisements or fashion magazines such as Vogue, Vanity Fair, or Elle.

Documentary photography
Documentary photography usually refers to a popular form of photography used to chronicle significant and historical events. It is typically covered in professional photojournalism, or real life reportage, but it may also be an amateur, artistic, or academic pursuit. The photographer attempts to produce truthful, objective, and usually candid photography of a particular subject, most often pictures of people.

Panoramic photography
Panoramic photography is a technique of photography, using specialized equipment or software, that captures images with 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. While there is no formal division between "wide-angle" and "panoramic" photography, "wide angle" normally refers to a type of lens, but using this lens type does not necessarily make an image a panorama.

Infrared photography
Top: tree photographed in the near infrared range. Bottom: same tree in the visible part of the spectrum. In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm.

Albumen print
The albumen print, also called albumen silver print, was invented in 1850 by Louis Désiré Blanquart-Evrard, and was the first commercially exploitable method of producing a photographic print on a paper base from a negative. It used the albumen found in egg whites to bind the photographic chemicals to the paper and became the dominant form of photographic positives from 1855 to the turn of the 20th century, with a peak in the 1860-90 period.

Hand-colouring of photographs
Hand-colouring (or hand-coloring) refers to any method of manually adding colour to a black-and-white photograph, generally either to heighten the realism of the photograph or for artistic purposes. Hand-colouring is also known as hand painting or overpainting. Typically, watercolours, oils, crayons or pastels, and other paints or dyes are applied to the image surface using brushes, fingers, cotton swabs or airbrushes.

Film still
A film still (sometimes called a publicity still or a production still) is a photograph taken on or off the set of a movie or television program during production. The photos were taken by studio photographers for promotional purposes. Such stills consisted of posed portraits, used for public display or free fan handouts, which are sometimes autographed. They can also consist of posed or candid images taken on the set during production, and may include stars, crew members or directors at work.

Landscape photography
Landscape photography is intended to show different spaces within the world, sometimes vast and unending, but other times microscopic. Photographs typically capture the presence of nature and are often free of man-made obstructions. Landscape photographers often attempt to document the space as well as convey an appreciation of the scenery.

Erotic photography
Erotic photography is a style of art photography of an erotic and even a sexually suggestive or sexually provocative nature. Though the subjects of erotic photography are usually completely or mostly unclothed, that is not a requirement. Erotic photography dating from 1835 until the 1960s is often referred to in the years since as vintage photography. Erotic photography should be distinguished from pornographic photography, which is of a sexually explicit nature.

Cottingley Fairies
The Cottingley Fairies appear in a series of five photographs taken by Elsie Wright and Frances Griffiths, two young cousins who lived in Cottingley, near Bradford in England. In 1917, when the first two photographs were taken, Elsie was 16 years old and Frances was 10. The pictures came to the attention of writer Sir Arthur Conan Doyle, who used them to illustrate an article on fairies he had been commissioned to write for the Christmas 1920 edition of The Strand Magazine.

Nude photography
Nude photography is a style of art photography which depicts the nude human body as a study. Nude photography should be distinguished from glamour photography, which places more emphasis on the model and her/his sexuality, and treats the model as the primary subject. Nude photography should also be distinguished from erotic photography, which has a sexually suggestive component. Nude photography is also distinguished from pornographic photography, which is of a sexually explicit nature.

Xunantunich (pronounced /ʃunantunit͡ʃ/) is an Ancient Mayan archaeological site in western Belize, about 80 miles (130 km) west of Belize City, in the Cayo District. Xunantunich is located atop a ridge above the Mopan River, well within sight of the Guatemala border – which is a mere 1 kilometre (0.62 mi) to the west. It served as a Maya civic ceremonial center in the Late and Terminal Classic periods to the Belize Valley region.

Monochrome photography
Monochrome photography is photography where the image produced has a single hue, rather than recording the colours of the object that was photographed. It includes all forms of black-and-white photography, which produce images containing tones of grey ranging from black to white. Most modern black-and-white films, called panchromatic films, record the entire visible spectrum. Some films are orthochromatic, recording visible light wavelengths shorter than 590 nanometres.

Image hosting service
An image hosting service allows individuals to upload images to an Internet website. The image host will then store the image onto its server, and show the individual different types of code to allow others to view that image. Hosting services have the potential ability to identify when and where their images are being used. When an image file is accessed, the image host is capable of logging the date and the general numeric internet address of the request.

Schlieren photography
Schlieren photography is a visual process that is used to photograph the flow of fluids of varying density. Invented by the German physicist August Toepler in 1864 to study supersonic motion, it is widely used in aeronautical engineering to photograph the flow of air around objects. Its role is changing due to the increasing use of computational fluid dynamics, which reduces the need for all such experimental fluid flow measurement techniques.

Aerial archaeology
Aerial archaeology is the study of archaeological remains by examining them from altitude. The advantages of gaining a good aerial view of the ground had been long appreciated by archaeologists as a high viewpoint permits a better appreciation of fine details and their relationships within the wider site context. Early investigators attempted to gain birdseye views of sites using hot air balloons, scaffolds or cameras attached to kites.
