In photography, the metering mode refers to the way in which a camera determines the exposure.Autobracketing is a feature of some more advanced cameras, whether film or digital cameras, particularly single-lens reflex cameras, where the camera will take several successive shots (often three) with slightly different settings. Two modes are used: The images are automatically combined, for example Automatic Exposure Bracketing into oneHigh dynamic range image, or the best-looking separately stored pictures can be picked later from the batch.White balance is a camera setting that adjusts for lighting in order to make white objects appear white in photos. This is more difficult than it might seem due to the fact that light cast from different sources is different in color (technically called temperature). That is to say, light is rarely truly white in nature. The light from an incandescent or halogen bulb, for example, is red/orange in color, while that from the sun is relatively blue. A proper white balance setting in a camera will prevent, for example, a white bed sheet in a photo from appearing orange in color when it is being illuminated by a candle.
