Photography: AEB (automatic exposure bracketing)

orginal post by dps blog

Have you ever found yourself in that situation when you get those very overexposed or very underexposed shots no matter what you do? Well AEB is your thing then, read below and enjoy this great thing.

Now AEB has made exposing a photograph alot easier, and you will get alot more detail in the final shot if you combine the given amount of exposures.

Most DSLRs (and some more advanced compact cameras) come with a feature called ‘Automatic Exposure Bracketing‘ (AEB) which can be useful to learn how to use in such situations.

By selecting it you can quickly take three shots (usually three) at different exposures without having to manually change any settings between frames. You can see an example of this below


When you select AEB your camera will choose the one exposure, the one that the will be given by your metering, once this selected the camera will one other shot on either side of this best guess (one over exposed (as in the left shot above) and one underexposed (as in the right shot above)).

This way you end up with the three images in a series with exactly the same composition but at different exposures for you to select the best of later on.

If you have the camera in burst mode (continuous shooting) the three shots will be taken if you hold down the shutter for a burst of three shots. If you’re in single shot mode the shots will take as you depress the shutter three times.

Each digital camera has a different way of selecting AEB, some like Nikon’s D70 have an accessible button on the back (marked BKT) while others (like Canon) have an AEB setting in their menus.

Check out your manual to see how AEB works on your digital camera. Most will allow you to change the variation between shots by different ’stops’. For example you might want a big variation between your three shots and would select a ‘2 stop’ gap or you might only want a slight variation and choose a ‘half stop’ gap. I generally start with a ‘1 stop’ variation and work from there.

Threw in a quick tip here, been moving stuff all day. Finally back home, tired worn out but i won't give up on you guys this easy. I just saw a thunderbolt going of outside, if there are more i m going to try capture one with my camera!
