Dave and all,
I think this is where the dialogue foundered, on the assumption that
this is like dye transfer. I've just found my book on color photography
and read the section on dye transfer, and I can't think of any way that
what Marion did could reasonably be called "basically a dye transfer" or
more generally, of any way that dye transfer provides a useful analogy
for what we're talking about here. This just reinforces my earlier
suspicion that we're talking about completely different things that
don't have any necessary logical connection to each other.
