The basic difference between scanning negs and chromes is that chromes
are a clear base, hence the same white point for every film type.
Negative film comes in many different emulsions, hence many different
white points. If you want to profile negative film, you would need an
IT8 target for every different kind, or, you could make one yourself
that would get you close. What you need is a reflective IT8 target,
some copy lights (3200 degree kelvin -tungsten or blue daylight bulbs),
a 35 mm slr camera with a matching filter for the lights, and of course
a variety of 35 mm film types. Shoot a bracket of about 7. 3
underexposed by at least a full stop, 1 on - perfect exposure, and 3
over exposed at least 1 stop each. You won't need prints, but you will
need the film processed. Pick up you film and start to build you
targets.
It works pretty good most of the time. The only trouble is that there
are so many varieties of the same film emulsion that you really will
have to keep good notes. I use the film emulsion # on the edge of the
film. Example Kodak. Gold 100 is now 100-5 on the emulsion. Good luck
and Good color...
