Scanning with Nikon CMS Off
If the Use Nikon Color Management System check-box in
the Color Management tab is off, profiles can not be used to
ensure that the data from the scanner are reproduced accu-
rately when passed to another application or displayed on the
monitor. Because the color profiles required for a calibrated
RGB or CMYK color space are not available when Nikon CMS
is off, images can only be scanned as uncalibrated RGB or
grayscale. Similarly, the absence of a monitor profile means that
gamma adjustment must be used to correct the image for dis-
play on your monitor or for editing in another application. These
adjustments to gamma are made in the Gamma tab of the Pref-
erences dialog (see below).

The illustration below shows how scanning proceeds when
Nikon CMS is off. The image shown in the preview window is
adjusted for display on the monitor according to the value cho-
sen for preview gamma in the Gamma tab. When the Scan
button is clicked, the main scan gamma and any changes to curves
and color balance are passed to the scanner, where they are
applied to scan data before the image is transferred to the host
application (if Nikon Scan is used as a "stand-alone" application,
the value for preview gamma is passed to the scanner instead of
main scan gamma). The LCH Editor and Unsharp Mask tools
can not be used when Nikon CMS is off.
