JPEG-HDR is an extension of JPEG, which supports images with high dynamic range. It was developed by a group that includes Radiance developer Greg Ward (see Radiance HDR), and is now apparently owned by Dolby Laboratories.

It is backward-compatible with standard JPEG viewers. The HDR data is stored in APP11[1] segments, and can be used to convert the image to one with high dynamic range.

See also JPEG XT, the presumed successor format.
