A high-resolution Nikon Dslr D5100 DX-format CMOS image sensor with an effective pixel count of 16.2-million pixels, an image processing engine that provides superior image quality and rich expression of tones, and the new High Dynamic Range (HDR) function. The High Dynamic Range (HDR) function captures two shots of varying exposure each time the shutter release button is pressed, and then combines the two shots into a single image with a broad dynamic range. Resulting images beautifully recreate the scene as seen with the naked eye, even with shooting of back lit scenes, with little or no loss of detail in shadows or highlights.
