Hum.  My scanner only changes exposure time (at least calculates exposure
time) during calibration, when it is basically calibrating the bulb and the
PRNU for the sensor.  I DO have manual control of the exposure time, so I
can change it my self...but the scanner doesn't re-calibrate for the film.

Yes, I understand your concern.  You may very well be correct.

Yeah, I don't believe "raw" is dependant on software at all, or at least it
certainly shouldn't be.
