Ok, I can accept that. It is a little more sophisticated than many, if not
most, film scanner applications which group all the various B&W settings
under the same single label and setting. However, "contrast indices" and
even "contrast masks" are quite different from color masks; so given the
original post, I believe that my response was appropriate and legitimate.
You are right, I am familiar with Kodak High Speed Infrared film; but did
not recognize the three-letter code (HIE), which I noted but did not
register and subsequently caused me to think it might be a new film. :-)
Since I do not use Vuescan, I cannot recommend a contrast/film setting from
among the list you provided; but I would follow the suggestion of another
poster who suggested one of the generic T-MAX unless one developed the film
with one of the developers listed to meet a known specified contrast range
in the original scene being captured on the film. If one really wants to
get into CIs (contrast Indexes) and film development procedures so as to use
the specific non-generic settings listed, I would recommend getting Kodak's
pamphlets on the processing of T-Max films which is a 30 page or so booklet
that discusses in detail such things. I do not know off-hand the Kodak
catalog # for the pamphlet.

Vuescan has settings for contrast indices of various black and white films,
not color masks. These settings may be used to adjust the exposure for
scanners that support this.
Kodak's High Speed Infrared film is probably the most commonly used
infrared film. If you are familiar at all with infrared films, you should
certainly have heard of this one, although you may not be familiar with it
under its three-letter code name (HIE). It is a silver-based film.
Vuescan has settings for the following black and white films:
KODAK T-MAX 100 Professional
KODAK T-MAX 3200 Professional
KODAK T-MAX 400 Professional
KODAK T-MAX T400 CN
KODAK TMAX-100 D-76 CI = .40 (D-76 Developer Contrast Index = .40)
KODAK TMAX-100 D-76 CI = .50 (D-76 Developer Contrast Index = .50)
KODAK TMAX-100 D-76 CI = .55 (D-76 Developer Contrast Index = .55)
KODAK TMAX-100 D-76 CI = .70 (D-76 Developer Contrast Index = .70)
KODAK TMAX-100 D-76 CI = .80 (D-76 Developer Contrast Index = .80)
KODAK TMAX-100 TMAX CI = .40 (TMAX Developer Contrast Index = .40)
KODAK TMAX-100 TMAX CI = .50 (TMAX Developer Contrast Index = .50)
