![]() ![]() The camera automatically adjusts the shutter speed to achieve proper exposure for the selected aperture.ĪPS-C – Advanced Photo System-Classic is an image sensor roughly one-third to one-half the size of a 35mm frame of film, or full-frame image sensor. An aperture of f/32 (also rare) makes essentially everything in a sweeping landscape sharp.Between those extremes are aperture values that produce varying depth of field.Īperture priority – A mode (abbreviated AV) available on nearly all advanced and some point-and-shoot digital cameras that allows the user to set a specified aperture value (in f-stops). An aperture of f1.4 (which only a few lenses can achieve), for example, is a very wide opening that puts very little of the image in focus. Aperture is measured in a unit called f-stops, in which smaller numbers actually represent larger openings. The smaller the aperture, the fewer of these off-angle light rays enter the lens, allowing more of the image to appear sharp. A large aperture allows in both light rays directed straight at the lens (which produce a sharp image) and those coming in at angles (which appear blurry). Aperture controls depth of field - how much of the image, from foreground to background, appears sharp. Aperture - In photography, an aperture is an adjustable opening in the lens that regulates how much light passes through. ![]()
