[Frameworks] Color separation experiment

[Scott Dorsey]

If anything is sharply colored, it will reproduce with a different tone
in each of the three films, so that may be a problem for you.

If it were me, I would just shoot three B&W reversal films and then have
the lab print them all together with three different timing lights for 
different colors.

If you're doing to try it on color film, try a standard color sep filter
pack:  #25 red, #58 green, #47 blue.  All of them will give the same exposure
on a grey card with daylight lighting, but obviously different exposures on
colored objects.  So much less tinkering and need to shoot tests.
