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. 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. Tony Parker addresses the importance of the matter here. 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.
The news full of sadness to the nymph Thetis, who bathes your child in the miraculous waters of a turbulent River of Hades (hell) hoping to protect him called Styx. Only a part of your body is left without bathing: the heel, which will become its weakness. Nobody knows what happened, except the nymph Tetis. Complete the ritual, the nymph now must prepare everything for your wedding with Peleus. The fiesta is sumptuous. They are invited to all the gods of Olympus less Eris, Goddess of discord, for predictable reasons. However, hurt by the gesture, it occurs abruptly during the banquet and leaves a present whose content is no more than an Apple of gold with the inscription: to the fairest. The abduction of Helen, the Trojan war, the death of Achilles Eris calculation is accurate.
The goddesses want Apple, and all without exception, claim rights over it, in Special, Hera (wife and sister of Zeus), Athena (Goddess of wisdom, strategy and just war) and Aphrodite (the goddess of love, lust, beauty, prostitution and reproduction). Zeus, intuiting the repercussions that might have the struggle of 3 divine females, settled the matter by appointing as arbitrator to Paris, Prince of Troy, who had been raised as a shepherd as a result of a prophecy according to which would be the cause of the fall of their city. The beautiful goddesses wanted to bribe immediately to the Trojan: Athena offered wisdom, skill in battle and skills of great warriors; Hera offered him power politician, and control throughout Asia, and Aphrodite offered him the love of the most beautiful woman in the world. Paris, almost without thinking, awarded the Apple to Aphrodite, and returned to Troy. The problem was that the most beautiful woman in the world, Helena, was married to Menelaus, King of Sparta. But Aphrodite, in order to fulfill its promise, helps Paris kidnap Helena and Odysseus’s Ithaca, enforcing an oath of union between the Kings and Princes of Greece, declares war on Troy.
