There's one more multi-shot feature on the Sony A55 that's worth mentioning; namely Auto HDR (High Dynamic Range). HDR photography increases the range of brightness values represented in a scene by combining two or more shots taken at different exposures, combining highlight detail from some and shadow detail from others. In the past, this has involved locking the camera down on a tripod, shooting several images at different exposures, and then working on a computer to combine them. Lately, though, the capability to do this directly in-camera has been appearing from a number of manufacturers, with varying levels of success. The auto HDR feature on the Sony A55 works pretty well, since the camera does the same micro-alignment trick it uses for its other multi-shot features. Options for HDR include an Auto setting, where the camera determines how much of the effect to apply, and manual settings ranging from 1 to 6(!) EV of exposure range.
