Dye Transfer was the method Created by Technicolor for color film.  In its history there where 4 processes.   Technicolor 4 was the last incarnation that was used until its relegation.   The materials for the process where made by Kodak but Technicolor made it own dyes until it stopped doing the process.  Yumm    For the aviator we created a digital method to reproduce as best we could the look but naturally while we had a lot of control we where limited by the dye's in current films to some extent.     If anyone would like I can make a action in Photoshop that will make a dye transfer look with controls that doesn't require a FILTER.

Yes.  There are a few print processes that don't use integral couplers
(the best known being dye transfer), but no film processes of any
currency other than Kodachrome (which is not actually current, but we
probably all have some in our files).

Yes.

(There are probably weird things an expert could find that don't last
longer in dry nitrogen in the dark, but most of them aren't very
"archival" to begin with.  Live plants and animals come to mind :-). )
