Yes ... I figured something like that was going on. As it turns out, the
R,G,B mask values all should be near 1.0. Ed's response to the newsgroup
implies the scanner, if 'negative' film is indicated, will boost the
exposure for blue and green.
Vuescan users should note the difference in mask values if the non-exposed
film is not measured. If not measured properly, I imagine all other white
balance options will not work properly.
