What Are Some Applications of HDR Images?
Anywhere you would use a conventional image, you can use an HDR image instead by applying a tone mapping operation to get into the desired color space. The reverse is not true, because a conventional, output referred image cannot have its gamut extended to encompass a greater range – that information has been irretrievably lost. Therefore, HDR image applications are strictly a superset of conventional image applications, and suggest many new opportunities, which we have only begun to explore. Below, we name just a few example applications that require HDR images as their input or as a critical part of their pipeline: Global illumination techniques (i.e., physically-based rendering) Mixed reality rendering (e.g., special effects for movies and commercials) Human vision simulation and psychophysics Reconnaissance and satellite imaging (i.e., remote sensing) Digital compositing for film Digital cinema The list of applications is continuing to grow, and in the future, we expect digital pho
