The EXPEED image processing system is at the heart of the D3’s ability to capture and process massive amounts of data at high definition. The EXPEED system includes both hardware and years of Nikon image processing experience. The D3 EXPEED system features 14-bit analog-to-digital (A/D) conversion with 16-bit image processing, both of which contribute to delivering results with Nikon’s signature ‘look and feel’ of rich accurate colours, smooth skin gradations and exceptional detail.
