firstly, thanks Jason for the report. always informative to hear about

i'm not sure you want that to be the case anyway. there's an awful lot
going into the emulsion design and lab process to make an OCN-IP dupe to be
something other than unity+Dmin delta. intermediate stock is rarely
actually processed at gamma 1.0 for all three color channels.
>I disagree (being a VFX person). We do want to know where CC is heading,
though, so graded samples are welcome. Most of the tme when we get pregraded
material, someone went nuts with the secondaries and we spend most of our
fighting our way back to something usable.
agreed. i've been frightened in a DI session when vfx shots have come back
to me to integrate with a sequence of a film that i've been grading only to
have to undo secondary corrections because 1. the plates were improperly
pre-graded or 2. the plates were graded to match the dailies, in other words
to look like HD when were making a film
but i've worked both ways. delivering simple offset graded plates to vfx as
well as raw scans and a color reference. wouldn't it be great if color
correctors could deliver grade info directly to vfx vendors to use in their
comp tree and update as things change?:) CDL is a good step for that
and i've also been in the unfortunately contentious positon of having to
tell comp supervisors that the 5 days of color wedging they've done on a vfx
sequence to get color just right was going to change in DI because of a time
of day shift due to editorial changes.
balance and compromise.
