One is to change the aperture, another is the shutter speed and the third is ISO. A tripod? Your DSLR has the answer! Automatic Exposure Bracketing is a function most DSLRs have to take three photos with only one click of the shutter, each in different exposures.
Canon allows users to adjust how much the exposure varies between each shot, but the Rebels only take three bracketed shots. The Nikon D has the bracketing feature as a shortcut marked "BKT" towards the lens barrel and turning the front and back control dials adjusts both the exposure compensation between each shot and the number of shots, up to five. Nikons without the shortcut button usually have the feature inside the menu. So how much should you bracket? AEB is a simple way to bracket — the trickiest part is just finding out where the setting is located on your particular camera model.
Exposure bracketing is a helpful technique for getting that exposure dead-on. Using AEB is a quick, efficient way of taking advantage of the method. But, while those shots are one right after another, the slight delay may not be for every shooting scenario. When detail is paramount and the exposure is tricky, AEB helps ensure you leave the shoot with the shots you need.
Shooting three images instead of one also opens up more possibilities in post processing: simply choosing the best of the three, dodging and burning the AEB layers or the popular high dynamic range or HDR technique. When you push the highlights down to on a blue hour or nighttime cityscape, you'll find that bright lights that were blown out in the exposure aren't "recovered", they're pushed to a muddy white that's incapable of retaining any color because the detail is gone.
And the more you blow out the core of the light sources, the uglier the transition around that core gets. And that's just one example. Shooting straight into the sun is another; try pushing the highlights down to to recover the sky and the area around the sun looks awful. Again, it's the transition area that suffers the most. I'm not saying bracketing should be used all the time; in fact, there are a lot of cases where people use it incorrectly because they don't understand the dynamic range of their cameras.
But when it's needed, there isn't really a substitute for it. Home Topics Architecture. The Human Eye Versus Camera Sensor Despite the obvious differences in vision and photography, our eyes and cameras work in a similar fashion, at least on a basic level.
Defining Bracketing By definition, bracketing is photographing a series of the same image, tweaking a single setting as you shoot. A series of bracketed exposures. The result of bracketed images after being composited: a natural-looking photo. Nikon's display for auto bracketing, showing five frames with one stop in between each. I took this image a decade ago when I was starting to learn about HDR.
This is an extreme example of HDR poorly done; my digital photo teacher at the time commented during the critique: "If this is an attempt at HDR, something went horribly wrong. Posted In:. Scott Mason is a commercial photographer in Austin specializing in architectural imaging.

David Hartwick - December 23, I've read that bracketing isn't suitable for shooting in Raw. Unless you have a very slow computer. Ariel Martini - December 23, Bracketing: Something Canon users have to learn to compensate the lack of dynamic range. Deleted Account - December 23, Always in a doubtful situation, very rarely with the built in bracketing function because I leave it switched on too often.
Vincent Alongi - December 23, I'm not a huge landscape photographer but will fiddle with it more next spring. Thanks for commenting! Should you delete the extra shots right away? No, if storage permits, keep all three shots until you get home and upload them to your PC and into an image editing software, such as Photoshop.
By using the layers functionality of Photoshop or similar functionality of another image editing software , you can load all three shots into different layers and then carefully erase the under-exposed or over-exposed part of one or more layers to end up with a final shot where both the main subject and the surroundings are properly exposed!
This Photoshop functionality allows you to shoot in very extreme lighting situations where there are many parts in different intensity of light and shadows such that you are losing details in the highlights and shadows. In this case, you might need more than two extra shots to obtain details in the different parts. Without moving the camera a tripod is essential here , take as many shots as you need, exposing for the different parts you want details to be visible.
Used judiciously, exposure bracketing is a simple technique that can ensure proper exposure of a difficult lighting situation. Make sure you get a camera with good manual Bracketing control.
