Re: Help with HLG profile

The current ACES RRT renders into a virtual display HDR wide colour
gamut space (extremely similar to  a 10000Cd/m^2, Rec 2020 display).
The ODT targets this intermediate data into a specific real display,
say P3, Rec709/1886 etc. The general assumption is that it targets a
dark viewing environment, and that adaptations are currently placed
into the ODTs to deal with some of the image rendering adjustments
needed to compensate for dim viewing etc.

The work going on to revisit the RRT/ODT is trying to resolve some of
the issues that arise out of this particular split of
responsibilities, as well as trying to widen the applicability to
other viewing situations (personally I'd like to remove some of the
colour adjustments as they limit the available colour range and looks
that you can create).

ACES is definitely not limited to cinema viewing, Framestore use it
across almost all of our different delivery mediums, and yes we have
hit some of its limits so I'm not a total fanboy - but have provided
constructive feedback!
