Re: High Dynamic Range imaging and ICC colour management

Hi Craig,

This is very interesting and something we have been looking at in the
context of applications running on Games Consoles and Set Top Boxes where
the output is locked to HDR (when the TV supports), to avoid the problems
associated with HDR / SDR switching on the HDMI link.

I'd like to introduce my colleague Joe Drago (who joined this list after
your post, which is the main reason for this message). He has some comments
/ questions.
