... and presenting 0.0 as black and 1.0 as white internally is
totally out of the question?
No. :-)
There is more. I can't see we have adressed "what kind of black"
and "what kind of white".
* Aquisition medium black and white ?
(e.g. from max density in the film emulsion to a clear base)
* Display black and white ?
(e.g. the monitor's brightness range)
* Scene referred ?
(From black hole to supernova, if you have bits to burn.)
HDR computer graphics can be scene referred, and film scans
will likely be media referred. They can be easily represented
in full range inside the program, but at display time they
have to be remapped to a range that the screen can manage.
This remapping is typically lossy, often very much so.
You don't want to do it at import time. Well, for some
workflows you DO want that. But not as the default, right?
This is getting hairy. Should Cinelerra have two modes or
workflows; one for "conformed" video editing, and one for
high tonal fidelity grading and compositing?
