yes, but in the case of some telecine work the objective is not
to try to get the full range from the film but rather to
abbreviate it and add the specific artifacts that an element like
print provides, like grain, sometimes streaking, black dirt
rather than white, even weave from an optical printer.  And there
are other less definable qualities of the print that a colorist
can feel by working with it.

It's not a trivial decision to work from print and had to be
justified over and over again in the years I took with it, by
testing and dialogue.. it's extremely expensive.   And again,
it's not for telecine when your objective is detail and rendition
faithfulness, but in the beginning anyway, film itself is a
translation, and print is a translation of the negative.
