podverganie it is defined as, how many light amazes the chamber gauge. It depends on parametres of adjustment of the chamber mainly speed of a shutter and the aperture. Value podverganija (known as EV) is number which represents settlement podverganija chambers. We will explain, that means number and as it is used for indemnification podverganija.
podverganie depends on two things: how many light passes through lenses on the gauge of the chamber and as long the gauge is exposed. Former - function of value of the aperture, while last - function of speed of a shutter. Value podverganija - number which represents this potential quantity of light which could amaze the gauge. It is important to understand, that value podverganija - a measure of how the exposed gauge should shine and not a measure of that, how many light actually amazes the gauge. Value podverganija is independent of that, how much shined a scene. For example the pair of value of the aperture and speed of a shutter represents the same value podverganija both if the chamber is used within very bright day or within dark night. Each number of value podverganija represents all possible shutter and parametres of adjustment of the aperture which result besides most podverganiju.
Though value podverganija - the same for various combinations of values of the aperture, and a shutter is accelerated, the turning out photo can be absolutely excellent (the aperture operates depth of area while speed of a shutter operates, how many movement it is grasped), EV 0.0 is defined as podverganie, establishing the aperture in f-number 1.0 and speed of a shutter by 1 second. All other values podverganija concerning that number. Values podverganija are on a basis of two logarithmic scales. It means, that each separate step EV – plus or a minus 1 – represents podverganie (actual light which amazes the gauge) to be divided on two or doubled. It is improbable, that you establish absolute values podverganija. The majority of chambers does not support an input in value podverganija in general. You will use however values podverganija, establishing indemnification podverganija.
Indemnification podverganija - a way to establish the chamber in podverganie which more low or above than, that was automatically revealed. avto settlement podverganija chambers not perfectly and in some results of scenes in finished or under the exposed photos. In such cases indemnification podverganija can solve indemnification podverganija of a problem, also it is useful, when you like to receive photo which are a little finished or under the exposed. Establishing indemnification podverganija you choose value podverganija which is added to current settlement podverganija. Usually value of indemnification podverganija has more, than +/-5 EV. For example indemnification-2EV will make a photo of more dark (or less exposed) while indemnification +2EV will make it brighter (or more exposed).
The good example of use of indemnification podverganija is in bright day. Give indemnification to lower podverganie, using value-0.5EV or-1EV to receive richer colours and more details. Values podverganija can be used also in connection with avto the conclusion in brackets. Using the car podverganija, bracketing each time when you take a photo, the chamber takes a number of additional photos for you everyone with little bit various podverganiem. You can establish step EV between each photo. |
