Exposure Bracketing

Exposure Bracketing - To illustrate this in more detail, lets look at an example.

Your camera tells you that for the scene you are photographing, you need a shutter speed of 125th/sec and an aperture of F8. With exposure bracketing, and depending on whether you are in Tv (shutter priority) or Av (aperture priority) mode, you can alter the shutter speed or aperture for each shot.

So, if you are in aperture priority mode and set up for a 1 stop bracketing shot, your camera will adjust the shutter speed and you will end up with the following 3 exposures (as above);

• 125th/sec @ F8 - correct exposure

• 60th/sec @ F8 - overexposed 1 stop

• 250th/sec @ F8 - underexposed 1 stop

If you are in shutter priority mode, your camera will adjust the aperture values and you will end up with the following;

• 125th/sec @ F8 - correct exposure

• 125th/sec @ F5.6 - overexposed one stop

• 125th/sec @ F11 - underexposed one stop

Exposure +/- Bracketing - Why and when would you use it?

Do you expose for the light area or dark? Do you use fill in flash or pull details from the dark areas in post processing?

If the range is quite broad and the scene is quite difficult (much like the white of a wedding dress against the black of a wedding suit), you could expose the first shot to a neutral area (not too bright and not too dark) and use a 1 or 2 stop bracketing exposure to ensure that one is correct.

Note: With weddings, I would first of all shoot RAW for security and peace of mind, and I would take my reading from the dress.
