HDR is high dynamic range. In photography, this range is measured in units of 'stops', which refers to each increment of an f-stop, a shutter fraction, or ISO step (you will need a full understanding of photography to get that). At any rate, a typical full stop range of any scene to human eye is 10 stops. Film cameras get a range of about 4-5 stops. Digital cameras get a range of about 3-4 stops. These are not precise, but you get the idea. At the 1st stop is absolute black. At the 10th stop is absolute white. If you have a scene that goes beyond the stop range of a digital camera, you can use HDR, which takes images taken at different stop ranges and combines them into one image. HDR can be done either through HDR merging (found in photoshop or other software) or simple cut-and-pasting (also found in photoshop).
