Black and white is two dimensional... the film will have different black and
white points with various camera settings, and you will need to get the
maximum levels out of the particualr range each image offers. Between there
all that is left is a simple curve for offering an even gradiant to the
image. This curve may vary with the exposure as well. So scanning raw high
bit grayscale, opening in Photoshop, applying an appropriate curve (ideally a
one point gamma curve, but it might be a more complex shape with multiple
points) would be one preferred workflow, that would take no skill at the
scanner, and capture all available data for later use. You could create a
Photoshop action to do much of this (invert, set B&W points, apply curve,
downsample to eight bits), but since the B&W points may vary, setting those
manually, and perhaps just applying a saved curve would be more practical.
This is not a process that lends itself to ICC profiles.
