[Bf-committers] Scene Linear Middle Grey Assumptions

[Troy Sobotka]

Can anyone cite where Blender's internal representation of middle grey
is? Has one been defined?

It would seem that for ingestion and output, the reference model would
be wise to locate one. For example, within Open Color IO, the
reference compositing space appears to select a value that aligns with
the optical middle grey value of 0.18[1]

As we move further along toward a proper color managed workflow, I'm
hoping we can get some hard data on what is happening internally
currently and why.

With respect,
TJS
