Lo-fi Photography
Lo-fi photography ("lo-fi" meaning low-fidelity, referring to "any process which fails to achieve the accuracy and 'transparency'") refers to unconventional photographic practices, chosen for aesthetics, which give an impression of low quality. Popular techniques include the use of toy cameras or pinhole cameras, for their distinctive stylistic effects. It can be considered a reaction to the perceived ease of creating technically perfect photos in the digital age. Some emphasize a return to film, while others use digital technology to accomplish the same effects. Low-fidelity photography has also been commonly linked with lo-fi music as well. Details Lo-fi photography uses film or digital photography techniques to create more of a soft, unusual look to photos compared to the crisp and high definition photographs that standard photography aims to provide. These lo-fi images can be any combination of distorted, soft, hazy, under/over exposed and in any way unusual. Often, creating ...

Fidelity
Fidelity is the quality of faithfulness or loyalty. Its original meaning regarded duty in a broader sense than the related concept of ''fealty''. Both derive from the Latin word ''fidēlis'', meaning "faithful or loyal". In the City of London financial markets it has traditionally been used in the sense encompassed in the motto "My word is my bond". Audio and electronics In audio, "fidelity" denotes how accurately a copy reproduces its source. In the 1950s, the terms " high fidelity" or "hi-fi" were popularized for equipment and recordings which exhibited more accurate sound reproduction. For example, a worn gramophone record will have a lower fidelity than one in good condition, and a recording made by a low budget record company in the early 20th century is likely to have significantly less audio fidelity than a good modern recording. Similarly in electronics, fidelity refers to the correspondence of the output signal to the input signal, rather than sound quality, as in t ...

Cross Processing
Cross processing (sometimes abbreviated to Xpro) is the deliberate processing of photographic film in a chemical solution intended for a different type of film. The effect was discovered independently by many different photographers often by mistake in the days of C-22 and E-4. Color cross processed photographs are often characterized by unnatural colors and high contrast. The results of cross processing differ from case to case, as the results are determined by many factors such as the make and type of the film used, the amount of light exposed onto the film and the chemical used to develop the film. Similar effects can also be achieved with digital filter effects. Processes Cross processing usually involves one of the two following methods. * Processing positive color reversal film in C-41 chemicals, resulting in a negative image on a colorless base. * Processing negative color print film in E-6 chemicals, resulting in a positive image but with the orange base of a normall ...

Sprocket Hole Photography
Sprocket hole photography is a style of photography that exposes the full width of 35 mm film, creating a photograph punctuated by the "sprocket holes" (perforations) along the edges of the film. Usually, this style involves the use of a modified medium format Medium format has traditionally referred to a film format in photography and the related cameras and equipment that use film. Nowadays, the term applies to film and digital cameras that record images on media larger than the used in 35&nbs ... camera, since a 35 mm camera ordinarily will not expose the edges of the film.

Redscale
Redscale is a technique of shooting photographic film where the film is exposed from the wrong side, i.e. the emulsion is exposed through the base of the film. Normally, this is done by winding the film upside-down into an empty film canister. The name "redscale" comes because there is a strong color shift to red due to the red-sensitive layer of the film being exposed first, rather than last C-41_process.html"_;"title="he_red_layer_is_normally_the_bottom_layer_in_C-41_process">C-41_(color_print)_film_All_layers_are_sensitive_to_blue_light,_so_normally_the_blue_layer_is_on_top,_followed_by_a_filter._In_this_technique,_blue_light_exposes_the_layers_containing_cyan_and_magenta_dyes,_but_the_layer_containing_yellow_dye_is_left_unexposed_due_to_the_filter._E-6_process.html" ;"title="C-41 process">C-41 (color print) film">C-41_process.html" ;"title="he red layer is normally the bottom layer in C-41 process">C-41 (color print) film All layers are sensitive to blue light, so normally t ...

Instant Camera
An instant camera is a camera which uses instant film, self-developing film to create a chemically Photographic processing, developed print shortly after taking the picture. Polaroid Corporation pioneered (and Patent, patented) consumer-friendly instant cameras and film, and were followed by various other manufacturers. The base of the technology is from a Hungarian chemist, Rott Andor. His invention, direct positive photography, also known as DTR (Diffusion Transfer Reversal) was patented in 1939. With the DTR process, the photographed surface or object immediately appears as a positive, which is an image corresponding to the dark and light shades of the original. When developing the image, the fixer and the developing material are present at the same time, and they immediately interact. The invention of commercially viable instant cameras which were easy to use is generally credited to United States, American scientist Edwin Land, who unveiled the first commercial instant ca ...

Pinhole Camera
A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called ''pinhole'')—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. History Camera obscura The camera obscura or pinhole image is a natural optical phenomenon. Early known descriptions are found in the Chinese Mozi writings (circa 500 BCE) and the Aristotelian ''Problems'' (circa 300 BCE – 600 CE). Ibn al-Haytham (965–1039), an Arab physicist also known as Alhazen, described the camera obscura effect. Over the centuries others started to experiment with it, mainly in dark rooms with a small opening in shutters, mostly to study the nature of light and to safely watch solar eclipses. Giambattista Della Porta wrote in 1558 in his Magia Na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toy Camera
A toy camera is a simple, inexpensive film camera. Despite the name, toy cameras are fully functional and capable of taking photographs, though with optical aberrations due to the limitations of their simple lenses. From the 1990s onward, there has been interest in the artistic use of such cameras or recreation of this style, both with cameras originally designed for children, and others originally intended as mass-market consumer cameras. Many professional photographers have used toy cameras and exploited the vignetting, blur, light leaks, and other distortions of their inexpensive lenses for artistic effect to take award-winning pictures. Toy camera photography has been widely exhibited at many popular art shows, such as the annual "Krappy Kamera" show at the Soho Photo Gallery in the Tribeca neighborhood of New York City. Various publications such as ''Popular Photography'' magazine have extolled the virtues of the Diana camera in its own right as an "art" producing im ...

Fisheye Lens
A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective ( rectilinear images), fisheye lenses use a special mapping ("distortion"; for example: equisolid angle, see below), which gives images a characteristic convex non-rectilinear appearance. The term ''fisheye'' was coined in 1906 by American physicist and inventor Robert W. Wood based on how a fish would see an ultrawide hemispherical view from beneath the water (a phenomenon known as Snell's window). Their first practical use was in the 1920s for use in meteorology to study cloud formation giving them the name "whole-sky lenses". The angle of view of a fisheye lens is usually between 100 and 180 degrees, although lenses covering up to 280 degrees exist (see below). Their focal lengths dep ...

Reversal Film
In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. Instead of negatives and prints, reversal film is processed to produce transparencies or diapositives (abbreviated as "diafilm" or "dia" in some languages like German or Hungarian). Reversal film is produced in various sizes, from 35 mm to roll film to 8×10 inch 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. The most common form is the 35 mm slide, with the image framed in a 2×2 inch cardboard or plastic mount. Some specialized labs produce photographic slides from digital camera images in formats such as JPEG, from computer-generated presentation graphics, and from a wide variety of physical source material such as fingerprints, microscopic sections, paper documents, astronomical imag ...

Exposure (photography)
In photography, exposure is the amount of light per unit area (the image plane's illuminance times the exposure time) reaching a frame of photographic film or the surface of an electronic image sensor, as determined by shutter speed, lens F-number, and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region. An "exposure" is a single shutter cycle. For example, a long exposure refers to a single, long shutter cycle to gather enough dim light, whereas a multiple exposure involves a series of shutter cycles, effectively layering a series of photographs in one image. The accumulated ''photometric exposure'' (''H''v) is the same so long as the total exposure time is the same. Definitions Radiant exposure Radiant exposure of a ''surface'', denoted ''H''e ("e" for "energetic", to avoid confusion with photometric quantities) and measured in , is given by :H_\mathrm = E_\mathrmt, where *''E'' ...
