Description

HD Photo is a file format developed by Microsoft for continuous-tone still images. It supports multiple color formats for display and print, high-dynamic-range image encoding, lossy or lossless compression, and efficient decoding for multiple resolutions and subregions.

The HD Photo format provides compression quality comparable with JPEG-2000 and more than twice the quality of the standard JPEG format. It is also known as the "Windows Media Photo" format.
