High Dynamic Range imaging and ICC colour management

I have been asked to post a presentation that I made in last month's ICC meeting to this group. The links below are to my presentation and a recording of the meeting including discussion.

This presentation was the result of discussion with several experts from different areas, some of whom are members of this group. The problem that we are trying to address is that of effective presentation of High Dynamic Range (HDR) and Standard Dynamic Range (SDR) images or video sequences on the same display. This is particularly relevant where the content creator is not able to control the way in which the content is rendered to the display or to broadcast content appropriate to a specific display.

An effective solution to this problem requires an architecture similar to that of the ICC where an input transform maps colour content to a well-defined 'connection space' and an output transform maps from this connection space to a device (usually a display or printer). Although the presentation is from an ICC perspective, other models could be used.

This is a very basic outline of one possible solution to this problem and at this stage I am interested to identify others (from this group and elsewhere) who would be interested in working further on this topic. The response from the ICC was very positive and I believe that the ICC would be willing to host a forum for this discussion, especially to explore whether the current ICC model (with minor extensions) would be useful.

I would be happy to present these ideas in more detail if anyone is interested.

In the meantime, please let me know if this is something you would like to work on or if you are already aware of other solutions or proposed solutions to this problem.

Best regards,
Craig Revie
