They generally incorporate some advanced features - such as larger sensors, more powerful processors or sophisticated controls - but their lenses are not removable. The most common kind of auto-bracketing is exposure bracketing, but ISO, white balance, flash and focus can also be bracketed in many cameras.īridge camera – This camera type falls between simple point-and-shoots and DSLRs or mirrorless cameras in both size and capabilities. Most point-and-shoot cameras capture 10-bit or 12-bit images, while better DSLRs and mirrorless cameras capture at 12-bit or 14-bit.īracketing – Setting a camera to automatically take two to six quick shots with a change in a single setting to increase the chance of getting a perfect shot.
Higher bit depth allows more accuracy and fidelity of captured images, and allows finer adjustments when editing. BSI is usually found in smaller sensors, such as those in some Nikon and Samsung mirrorless cameras, Sony point-and-shoot cameras and various smartphones, such as newer Apple iPhone and Samsung Galaxy S models.īit depth – The level of gradation used to define a shade of dark or light. APS-C image sensors are used in most consumer-level DSLRs and in many mirrorless cameras.īackside illuminated sensor – Often abbreviated as BI or BSI, it's a type of image sensor designed to absorb more light in dim conditions. 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.
