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 accurately 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 display on your monitor or for editing in another application. These adjustments to gamma are made in the Gamma tab of the Preferences 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 chosen 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.
