Candid photography
A candid photograph is a photograph captured without creating a posed appearance. This is achieved in many ways, for example:
when the subject is in motion,
by avoiding prior preparation of the subject,
by surprising the subject,
by not distracting the subject during the process of taking photos.
Thus, the candid character of a photo is unrelated to the subject's knowledge about or consent to the fact that photos are being taken, and unrelated to the subject's permission for further usage and distribution. The crucial factor is the actual absence of posing. However, if the subject is absolutely unaware of being photographed and does not even expect it, then such photography is secret photography, which is a special case of candid photography.
The person who is generally credited with being the first available light "candid" photographer is Dr. Erich Salomon who photographed the social elite in Berlin, Germany and politicians and diplomats during the late 1920s and early 1930s with a 1 3/4 x 2 1/4 glass plate or cut, sheet, film camera called the Ermanox, fitted with an f/1.8 Ernostar lens.
Camera equipment -
Unobtrusive camera equipment, often small in size, is preferred for candid photography to avoid disturbing subjects. Black-painted cameras have long been preferred.
Candid photography also typically requires use of available light since flash alerts subjects to the camera and may startle them, causing them to react or become self-conscious and stage their photo appearance rather than behaving naturally. For this reason, early candid photography took place outdoors, where the sun provides ample light. Indoor candid photography required the development of more sensitive films with higher film speeds (ISO) and aggressive methods of developing films ("push processing") to increase sensitivity. Therefore, candid photography was historically associated with the grainy, high contrast images that result from these techniques. The introduction of digital cameras has made it easier to take pictures in low light conditions without flash.[3] Full-frame DSLR cameras have brought high-ISO noise to historically low levels, allowing for clean, saturated images at speeds up to and beyond ISO 6400.
Although point and shoot cameras with affordable lenses have been used widely for candid photography, the resulting photographs can suffer from vignetting, distortion and over saturation of color. Due to short reaction times for the photographer, exposure or focus may be slightly off. Since flash cannot be used, pictures are often taken at low shutter speeds and show blurring from movement of the subject, or camera shaking. All these faults are usually considered acceptable because of the limitations of candid photography.
Candid film photographers have been forced to use black and white, rather than color film because of its greater film speed. This has given candid photos a characteristic appearance. Film provides roughly 3 stops more dynamic range compared to earlier digital cameras. However, improved, smaller digital cameras are providing photographers with increased dynamic range, greater lens speeds and sharpness, enabling them to capture high quality candid images.
Lomo rule photography describes the fashion of using inexpensive Russian point-and shoot-cameras for candid photography.
