Photography

Photography is the art, application and practice of creating durable images by recording light or other electromagnetic radiation, 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, ..

35 mm format

The 35 mm format, or simply 35 mm, is the common name for the 36×24 mm film format or image sensor format used in photography. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43 mm. It has been employed in countless photographic applications including single-lens reflex cameras, rangefinder cameras, mirrorless interchangeable-lens digital cameras, digital SLRs, point-and-shoot film cameras, and disposable film cameras. The format originated with Oskar Barnack and his introduction of the Leica camera in the 1920s. Thus it is sometimes called the Leica format or Ba ...

Chronophotography

Chronophotography is a photographic technique from the Victorian era, which captures multiple phases of movements. The best known chronophotraphy works were mostly intended for the scientific study of locomotion, to discover practical information for animal handlers and/or as reference material for artists. Although many results were not intended to be exhibited as moving pictures, there is much overlap with the more or less simultaneous quest to register and exhibit photographic motion pictures.

Strip photography

Strip photography is a photographic technique of capturing a 2-dimensional image as a sequence of 1-dimensional images over time, rather than a single 2-dimensional at one point in time. As one moves across, one moves in time in addition to moving in space. The image can be loosely interpreted as a collection of thin vertical or horizontal strips patched together, hence the name. This is correct if the strips are discrete, as in a digital sensor that captures one line at a time, but in film photography, the image is produced continuously, and thus the "strips" are infinitesimal – a smooth ...

Infrared photography

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. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared light pass through to the camera, but blocks all or most of the visible light spectrum. When these filters are used together with infrared-sensitive film or sensors, "in-camera effects" can ...

Analog photography

Analog photography is a misnomer for Film Photography which uses a physical, non-electronic recording medium, where light is captured by sensitive silver particles, and the image will remain printed when processed chemically. This method was traditionally used for more than a century, prior to more recent Digital Photography based on electronic sensors. Lomography defines analog photography as photography using an analog camera and film. This is incorrect as analog describes an instrument whose output is the continuous function of time, which has a constant relation to the input. Neither f ...

Color histogram

In image processing and photography, a color histogram is a representation of the distribution of colors in an image. For digital images, a color histogram represents the number of pixels that have colors in each of a fixed list of color ranges, that span the images color space, the set of all possible colors. The color histogram can be built for any kind of color space, although the term is more often used for three-dimensional spaces like RGB or HSV. For monochromatic images, the term intensity histogram may be used instead. For multi-spectral images, where each pixel is represented by a ...

Film grain

Film grain or granularity is the random optical texture of processed photographic film due to the presence of small particles of a metallic silver, or dye clouds, developed from silver halide that have received enough photons. While film grain is a function of such particles it is not the same thing as such. It is an optical effect, the magnitude of which depends on both the film stock and the definition at which it is observed. It can be objectionably noticeable in an over-enlarged photographic film photograph.

Integral imaging

Integral imaging is an autostereoscopic and multiscopic three-dimensional imaging technique that captures and reproduces a light field by using a two-dimensional array of microlenses, sometimes called a flys-eye lens, normally without the aid of a larger overall objective or viewing lens. In capture mode, in which a film or detector is coupled to the microlens array, each microlens allows an image of the subject as seen from the viewpoint of that lenss location to be acquired. In reproduction mode, in which an object or source array is coupled to the microlens array, each microlens allows ...

Micrograph

A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system ...

Fashion photography

Fashion photography is a genre of photography which is 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. Fashion photography has developed its own aesthetic in which the clothes and fashions are enhanced by the presence of exotic locations or accessories.
