The wonders of auto bracketing in digital cameras

By Jakob Jelling

Out of the millions of minor details of the technicalities of the digital cameras as a technologically advanced device the auto bracketing in digital cameras is one of the most fascinating portions that would be covered in this discussion. In order to be perfectly sane about the working of a good device a person must also have sane understanding of all the even trivial portions of it too, and this discussion is a focus to unravel such another topic in the way, that essentially covers auto bracketing in digital cameras.

Auto bracketing is a function that is appearing increasingly as a part of many cameras' feature set, but while standard exposure bracketing has been around for a number of years, digital photography takes the concept further, and a range of bracketing functions are available. While bracketing for one thing or another is often possible manually, auto bracketing makes the process easy, and error-proof. With this article, we'll explain each type, and show its effect. The concept behind bracketing is simple; it is a way to ensure that at least one image will be just what the doctor ordered. This is done by capturing images with variations over one of the parameters that control the quality of the exposure. With film cameras, the process automatically adjusts either the aperture or the shutter speed in modest increments, capturing 3 images of the same subject at slightly different exposure settings. With digital cameras, the process can be additionally varied over other parameters.

Of the entire auto bracketing systems, automatic exposure bracketing is the oldest and the most commonly available. Most commonly, exposure bracketing can be thought of as a way to vary the brightness of the exposure over a series of 3 frames. Some systems however take it further and offer bracketing over a series of 5 frames if desired. The increment used for the bracketing is determined in fractions of 1EV exposure value steps. Normal - 0.7 EV + 0.7 EV is the range. The auto bracketing process is fast, and usually records the first exposure using the values decided by the camera's meter, then one under exposure captured at the predetermined, or default, setting, then another exposure, this time slightly over exposed by the same increment. With some cameras the order in which each exposure of the bracketing process is done can be selected. For example, using zero to represent the camera's standard exposure, the process can be 0, -, +; or -, 0, +; or +, 0, -; which allows a lot of flexibility.

Hence as per a formal definition, auto bracketing is a technique used to take a series of images of the same scene at a variety of different exposures that bracket the metered exposure (or manual exposure). "Auto" simply means the camera will automatically take these exposures as a burst of 2, 3 or 5 frames with exposure settings of anything between 0.3 and 2.0 EV difference. This can be useful if you're not sure exactly how the shot will turn out or are worried that the scene has a dynamic range which is wider than the camera can capture. On a digital camera this can also be used to combine under- and overexposed images together to produce an image with more dynamic range than the camera can capture

The above discussion has covered most of the very important portions of the features of auto bracketing in digital cameras and it can be expected that this is the most significant impact that the technique of auto bracketing can have upon the minds of the users, readers and photographers who do have the right and the need to understand the importance of this fantastic functionality.
