Dolby is demonstrating HDR (High Dynamic Range) photo encoding on a smartphone at Mobile World Congress this week.

The technology combines a number of photos with different exposures to produce a final image that captures shadows and highlights without over-exposure or under-exposure. Each photo is saved as an JPEG-HDR file, which enables it to be viewed on conventional photo viewers. However, the additional HDR information remains in the image file, offering the opportunity of returning to the image after it was taken and using HDR software to adjust the exposure.
