INDEX

 The dark voltage level of each CCD element is slightly different

When properly calibrated, the scanner should theoretically produce the same values

for each pixel, if an image that is a single tone and color were scanned.

Sometimes the calibration data gets stored inside the scanner memory, sometimes it's

done once for every scan and sometimes VueScan stores the calibration data in a file

when the "Scanner | Calibrate" command completes.

If you've got one or two narrow streaks appearing in the scan direction, try doing a scan

with the scanner turned on its side. This can dislodge particles from the light path.

Scanner | Focus

This command focuses the scanner. The center of this focus area is displayed on the

preview with a small animated box, and can also be changed with the Crop | Focus X

offset (p. 69)and Crop | Focus Y offset (p. 69) options (options displayed only when the

scanner is capable of this).

Scanner | Exposure

This command computes the optimal values for Input | RGB exposure (p. 61)and Input |

Infrared exposure (p. 61). It uses the pixels inside the crop box in the Preview tab to

compute these values.

Scanner | Previous

Decreases Input | Frame number (p. 54) by 1.

Scanner | Next

Increases Input | Frame number (p. 54) by 1.

Profile | Profile scanner

See the section in this User's Guide describing ICC profiling of scanners, printers and

film.
