In photo: Several exposures can be combined into one, each exposed perfectly for certain parts of the photo, and themn merged so you see detail in sky (not overexposed) and shadow (usually dark).
Examples.

Please stop saying the bottom photo of the two submitted earlier has a HDR. |
Never said that.
HDR mimics the way the eye perceives lighting and details. You obviously didnt put much time into thinking about it. For example if you are in a dark room and walk out the door into bright daylight, it temporarily blinds you (for atleast a few seconds). Your eyes adjust and you are then able to see details etc. This is the same mechanic as a camera's exposure, which is the length of time light is let into the lens/film etc. Same mechanic with the eye, except its not based on an "exposure time" but based on the quantity of light that enters through your pupil. I am not a photographer but I certainly have enough experience with film, so if you want to throw crap my way make sure you think it through.
@Roy: He didnt nail much, HDR in games is completely different than HDR in photography. Seriously, dont say he nailed it because it makes you look stupid, when was the last time you say a print or a picture emiting light? Not often, but a monitor does. In basic theory its the same "physical mechanic" which is based on light and the eyes perception of said light, in practice photography and graphics engines are very different in nature.
Also HDR is an effect that can be toned down if they want to, but eliminating it is silly.
