The HDR Working Group exists to promote the use of ICC color management in High Dynamic Range (HDR) imaging.
<p>
Specifically, this group will:
<ul>
<li>Identify issues and limitations with the current specifications, implementations and use of color management in HDR imaging.
<li>Work with implementers of HDR color management, other international standard bodies, and working groups in the adoption of ICC HDR in their own specifications.
<li>Develop proposals for how to include HDR in ICC workflows.
<li>Prepare white papers and other educational materials to aid developers and users in the appropriate application of color management to HDR.
<li>Propose revisions to ICC specifications where required to address the needs of HDR workflows.
</ul>
