Conversely, the lower the number, the larger the opening, and so the more light that is let into the camera. The wider opening at the lower f-stops narrows the range of focus so the background of an image is blurry when focusing on the foreground, and vice-versa. This "depth of field" increases as the aperture closes, so that objects that are at differing distances from the camera can both be in focus; when the aperture is at its narrowest, the foreground and background are both in sharp focus. Shutter Main article: Shutter (photography) The shutter, along with the aperture, is one of two ways to control the amount of light entering the camera. The shutter determines the duration that the light-sensitive surface is exposed to light. The shutter is opened, light enters the camera and exposes the film or sensor to light, and then the shutter closes. There are two types of mechanical shutters. The leaf-type uses a circular iris diaphragm maintained under spring tension inside or just behind the lens that rapidly opens and closes when the shutter is released. A focal-plane shutter. In this shutter, the metal shutter blades travel vertically. More commonly, a focal-plane shutter is used. This shutter operates close to the film plane and employs metal plates or cloth curtains with an opening that passes across the light-sensitive surface. The curtains or plates have an opening that is pulled across the film plane during an exposure. The focal-plane shutter is typically used in single-lens reflex (SLR) cameras, since covering the film rather than blocking the light passing through the lens allows the photographer to view through the image through the lens at all times except during the exposure itself. Covering the film also facilitates removing the lens from a loaded camera (many SLRs have interchangeable lenses). Digital cameras may use one of these types of mechanical shutters or they may use an electronic shutter, the type used in the cameras of smartphones. Electronic shutters either record data from the entire sensor at the same time (a global shutter) or record the data line by line across the sensor (a rolling shutter). In movie cameras, a rotary shutter opens and closes in sync with the advancing of each frame of film. The duration is called the shutter speed or exposure time. The longer the shutter speed, the slower it is. Typical exposure times can range from one second to 1/1,000 of a second, though durations longer and shorter than this are not uncommon. In the early stages of photography, exposures were often several minutes long. These long exposure times often result in blurry images, as a single object is recorded in multiple places across a single image for the duration of the exposure. To prevent this, shorter exposure times can be used. Very short exposure times can capture fast-moving action and completely eliminate motion blur. Like aperture settings, exposure times increment in powers of two. The two settings determine the exposure value (EV), a measure of how much light is recorded during the exposure. There is a direct relationship between the exposure times and aperture settings so that if the exposure time is lengthened one step, but the aperture opening is also narrowed one step, the amount of light exposing the film or ------------------------------ End of alt.music.moxy-fruvous digest V14 #4281 **********************************************
