It's 3 pictures taken at 2 stops under exposed, normal exposure and 2 stops over exposed.
HDR is a range of methods to provide higher dynamic range from the imaging process.
Non-HDR cameras take pictures at one exposure level with a limited contrast range. This results in the loss of detail in bright or dark areas of a picture, depending on whether the camera had a low or high exposure setting.
HDR compensates for this loss of detail by taking multiple pictures at different exposure levels and intelligently stitching them together to produce a picture that is representative in both dark and bright areas.
By doing this you have an exposed image, which if you wish, you can then manipulate and exaggerate the exposure to give "artistic" effects, some people like this, some leave it as an HDR image with no further processing.
In my image the windows were totally blown out and the ceiling detail was not there among other things but by merging the 3images into 1 you end up with an image covering the full range.
Hope this helps, this is how I view it anyway.
