Auto bracketing is a means to the same object photographed exposure different multiple photos "siege" together to obtain the correct exposure photographs. The "automatic" means that the camera will automatically be taken objects photography shoot 2, 3 or 5 exposure in 0.3 to 2.0EV photos between (each photo exposure). When you are not sure the exposure is correct, you can use auto bracketing is a means to the same object photographed exposure different multiple photos "siege" together to obtain the correct exposure photographs. The "automatic" means that the camera will automatically be taken objects photography shoot 2, 3 or 5 exposure in 0.3 to 2.0EV photos between (each photo exposure). When you are not sure whether the correct exposure, you can use auto bracketing function to ensure the accuracy of the exposure, improve the quality of the photos. Digital camera on automatic exposure function, you can even let users owe exposures and too simple synthesis of photo painting exposure accurate picture — even when you're shooting and no photo exposure accuracy. We can see from the following examples of exposure enclosed in the application of a digital camera.
When you select the camera automatically after exposure to surround functionality, can often be set even photos quantity (the most typical for 2, 3 or 5 pieces), exposure settings (such as 0,-, + or-, 0, +, etc.).
Note the exposure setting in exposure value is the exposure compensation value.
The following is surrounded with exposure to extreme example of a top 5 photo exposure by level exposure compensation progressive.
If you do not have surrounded and use only normal exposure to light patterns telephoto, we only get the figure 3 (f/4.0, 1/160s) photos. In this example, + 2.0 EV is not being used as a synthetic pictures.
f/7.1, 1/306s, -2.0 EV； f/5.6, 1/224s, -1.0 EV； f/4.0, 1/160s, 0 EV
F/3.1, 1/71s, + 1.0 EV; f/2.8, 1/39s, + 2.0 EV; synthesis-2,-1, 0, + 1 EV
Some digital cameras also provides white balance auto surround feature.
