High Dynamic Range. You capture multiple shots, identical apart from shutter speed. The shutter speed is varied to give a range of exposures from 1-2 stops under to 1-2 stops over in 1 stop increments (although I prefer 1/2 stop increments). These are then blended in photoshop and the result is a 32 bit file which can't be displayed or printed as the dynamic range is too great for the average monitor or print media.
Converting the file back into a 16 bit file allows you to tweak it to show hightlight and shado detail, but the adjustments are quite difficult to do if you want to keep it looking relatively natural.
