indicate resolution.
Note that SFR is the spectrum of a slanted edge and gives a more

SFR.

Sharpness is determined by the 50% point and resolution is determined by
just visible lines (typically 5% to 10%). If the 50% frequency (fc) is
60cycles/mm, the the 10% to 90% transition width of a white-black step will

Thanks alot, Jawed!
The noise in the Nikon IV Vuescan is very low, and there is only a modest
slide, so you'd
be calibrating for that type of film. What about negs? What about other
brands of slide? Is the calibration just introducing colour shifts that
will have to be corrected anyway?
IT8 calibration with an Ektachrome slide for scanning Kodachrome is useless.

take more than a few hours to
add this to the firmware of most scanner manufacturers.
How about intelligent multi-scanning: The scanner checks for dark pixels
and if there are none in an area, it doesn't do multi-scanning on that line
of pixels, thereby speed up multi-scanning.
