Once set, all you need to do to shoot is simply continue pressing the shutter button. If you let go of the shutter button in the middle of auto bracketing, the pictures that have been shot up to that point will be recorded. If your camera has a sequential shooting mode, set this to its highest speed, then just press the button for the desired number of shots, this will help prevent camera movement changing the composition as you shoot.
The pictures will be recorded from left to right, in the following order:
[BKT] Correction value: 1.0 step EV / for 5 pictures. (Photos taken In cooperation with: JAL Private Resort Okuma)
Beyond just getting the right exposure, some cameras have a greater range for bracket exposure allowing you to do HDR (High Dynamic Range) photography. Setting the bracket number to the maximum of 5 or 7 images and the exposure bracket to 0.7 steps you can capture an image with a 3.5 EV range or 4.9 EV range depending on the camera. With third party software for your computer all these images can be combined into one image with much greater dynamic range, or for a more dramatic artistic image.
