Geartalk: HDR, High Dynamic Range

HDR, or High Dynamic Range, photography is a technique that allows for the darkest and lightest portions of the photo to be far apart and still allow for acceptable contrast. HDR images can be obtained by either computer rendering, or via the merging of several different photos that represent the exposure range being captured. Many modern enthusiast digital cameras facilitate this via automatic exposure bracketing (AEB), ranging from 3 to 9 shots. A typical 3-shot bracket may have the same photo at -1EV 0EV +1EV. Then software such as Lightroom is used to merge the photos together. The results can look something like this, 3-shot bracket, -1.3EV 0EV +1.3EV, Olympus E-PM1.
