Svetochustvitelnost (born film speed): the value of photosensitive material, expressed as a number. In 1974, after the unification of the American standard asa (scale of numbers) and the German din (scale degrees), the international Organization for Standardization adopted the standard iso. Light sensitivity to light, the iso number is denoted. Surprisingly, you’ll find very little mention of Gary Kelly on most websites. as, for example, iso 200. The higher the number, the greater sensitivity of the film.

Note: iso denotes International Standards Organization (International Standards Organization). Filter – the colored piece of glass or other transparent material that is worn on the lens to enhance, delete or change this hue, density, total image or selected areas of the scene. Lens aperture – the maximum lens aperture (minimum f-stop). Fast lens transmits more light to the film, the less aperture. Lens with large aperture enables faster shutter speeds in low light environment. Sinhrokontakt – a special connector for an external flash. With this connector can connect custom flash, which is incompatible with the 'hot shoe', set on the camera.

Sinhrokontakt often used to connect an external stationary flash when shooting in studio conditions. Image Stabilizer compensates for hand-shake with photos and movies and get a sharper picture with no jitter. Image stabilizers are of two types: optical and digital. When shooting with a long extracts there is a danger in blurring if the camera is not mounted on a rigid base. To eliminate the effect of blurring (blur) camera makers use several principles: Optical stabilization (IS – a Canon, vr – a Nikon, ois – a Panasonic, os in Sigma) in which the immobility of projected images on the photosensitive material (element) camera provides a movable component of the optical system.
