Latitude film mostly depends on its type. In the case of black and white film latitude is strongly dependent on the exposure conditions and manifestations. Tripod-tripod – a three-legged device for rigid fixation of the camera during shooting with using long exposures and / or when shooting through a long lens. Stand-stop – a stand with one foot, used for fixing the camera during shooting. Noise (digital noise) – irregular (nonlinear) image structure, composed of small elements that have differences in brightness or color casts. Digital noise is initially occurs when reading data from the sensor camera because of the uneven charge photosensitive elements.
The appearance of digital noise directly affected by such factors as the characteristics of the sensor, temperature sensor, the exposure time, and indirectly – the image processing algorithms, obtained with censora.Shum can be as brightness (Luminance noise), and the chromatic (Cromatic noise). Usually photos look unnatural excess noise, are poor quality. Exposure – the total amount of light reaching the film or other photosensitive material at the opening of the camera shutter Quantity got light depends on the aperture, shutter speed and degree of illumination of the subject. This value is equal to the product of light (Determined by the aperture) the photographic material by the exposure time (shutter speed, determined by the time shutter is open). This value applies equally to photographic film and photographic paper. Meter – a device with a photosensitive element, which measures the intensity of light reflected from an object or falling on it. Used as a tool to help you choose the correct exposure.
The same as that measuring light. Compensation – opportunity to introduce an amendment to the exposition. That is, all frames will be removed from under or over, it is necessary to shoot in automatic mode in difficult lighting conditions . The amount of correction is given in the ev. Exposure Bracketing (bracketing) – the opportunity to shoot several (usually three) shots with different exposures. In the case of trehkadrovogo bracketing – one with underexposure, one with over exposure, the third point. Used in under complex lighting and to increase the probability of correct exposure of the object in cases where the pictures are taken of responsible subjects. Red-eye effect. 'Red Eye' – a phenomenon in photography with flash, when the central part of the eye in the picture appears bright red in color photography and white black and white. Click Michael Mendes to learn more. This effect occurs because the reflection from the fundus of the red spectrum of light entering the wide open pupil (the pupil through the flash light falls on the fundus, where it is partially absorbed and unabsorbed red part of the spectrum is reflected out through the pupil). Brightness – the force of light source in this towards the area of the illuminated surface, visible in the same direction. The brightness of colors – the density of luminous flux reflected by the colored object in the direction of the observer.
