HDR

HDR, high dynamic range imaging, an imaging technique developed in the 1930s and 40s by Charles Wyckoff, using tone mapping with bracketed image exposures for a resultant image with a very high dynamic range. Various methods for HDR and HDR-like effects are now popular with digital photography. [wiki] [google]
