Assuming I was shooting film which is what I do in poreference to digital
capture, in the situation you describe above I would use the flashing
technique. This will allow the film to better encompas the tonal range of
the subject matter when working with as low a contrast fim as appropriate
for the job. Some may prefer to use duplicating stock, however I am happier
with the flashing technique as one is not constrained by the very slow speed
of the dupe film and the resultant reciprocity failure consideration.
May I ask how you would do it without resorting to digital comping?

Surely this is no different surely to biasing your exposure to take account
of subject matter, which you will be lighting so as to keep the picture
elements within the range of your chosen film.
