User manual NIKON SCAN 2.5 UPDATE

[. . . ] What's New with Nikon Scan 2. 5 About This Guide Welcome to Nikon Scan 2. 5!This electronic guide details improvements made to Nikon Scan since the release of Nikon Scan 2. 1. The information in this guide supplements and corrects the Nikon Scan 2. 1 reference manuals. While you will still need to refer to the reference manuals for complete instructions on using Nikon Scan, be aware that these manuals do not describe the present version of the product, and that the illustrations and many of the instructions are no longer current. [. . . ] The default value for each of the LEDs in the scanner's light source is ± 0EV; the gain for all LEDs or for each LED separately can be set to values between ­2EV and +2EV. Changes to analog gain do not apply until a preview or main scan is performed, and only take effect when the Apply A. See "The Scan Window: the Status Display, " above.

Scanner Extras/Miscellaneous settings are shown below. Calibrate With Nikon Scan 2. 5, a Calibrate button has been added to the Scanner Extras/Miscellaneous settings for the LS-2000 and COOLSCAN III film scanners. Recalibration can be performed with the MA-20, SA-20, or optional IA-20 adapter inserted in the scanner (manual calibration is not necessary when the SF-200 slide feeder, available separately for the LS-2000, is inserted in the scanner). If you are using the SA-20, the film will be ejected during the calibration and fed back into the scanner when calibration is complete. In the case of the IA-20, you will be prompted to rewind the film before calibration begins. To start calibration, click the Calibrate button. Changes from Nikon Scan 2. 1 include the addition of a Calibrate button and more options for negative prescans. See also For more information on scanner extras, see: · "Appendix A: Scanner Extras" Nikon Scan for Macintosh Reference Manual pages 109­116 Nikon Scan for Windows Reference Manual pages 122­129 Note Under most circumstances, calibration is performed automatically at intervals when no media are inserted in the scanner. Manual calibration using the Calibrate button is only necessary when film has been left in the scanner for a long period of time. The Scan Window: Design Changes - 21 - Prescan Mode When scanning film negatives, a prescan is necessary to obtain the best results. Selecting "negative" as the media type activates a menu of prescan options in the Scanner Extras/Miscellaneous settings sheet. Nikon Scan 2. 5, in combination with firmware versions 1. 3 or later, offers a choice of four prescan settings (shown at right) for different kinds of images. Automatic This is the recommended setting in most circumstances, suited to images that show a normal balance among shadows, mid-tones, and highlights. Use a different setting only if you experience problems scanning negatives using the automatic setting. Lo-Cont. Highkey This setting is suited to low-contrast images with clearly-defined white areas, but no clear shadows. An example of such an image would be a photograph of white clouds in a blue sky. Lowkey This setting is suited to low-contrast images with clearly-defined black areas, but no clear highlights. Neutral This setting is suited to low-contrast images in which mid-tones predominate, with no clearly-defined areas of black or white. An example would be a photograph of red rose against a green background. Note The negative prescan mode menu shown above is only available when Nikon Scan 2. 5 is used with LS-2000 or COOLSCAN III firmware versions 1. 3 or later. The current firmware version for your scanner is displayed in the title bar of the scan window. The Scan Window: Design Changes - 22 - Nikon Color Management The Nikon Color Management System, or Nikon CMS, ensures that the image data from your Nikon scanner are reproduced faithfully on your system's monitor or printer. With this powerful tool, you can manipulate colors in either a CMYK or calibrated RGB color space before the data are passed to your imaging application. Profiles detailing the color characteristics of the chosen color space and the output device (monitor or printer) ensure that colors will be reproduced accurately in almost any operating environment. The release of Nikon Scan 2. 5 marks a number of improvements to the color-management system used in earlier versions of Nikon Scan 2. These include: · profile information can be passed to the host application (Macintosh only), and is stored with images saved using the Nikon Scan applet or main window · profiles for the RGB color space can be chosen from a list of options in the Preferences dialog · because monitor and RGB profiles contain gamma settings specifically designed for a given monitor and platform, adjustments can now only be made to gamma when Nikon CMS is off (in earlier versions of Nikon Scan 2, it was possible to make further adjustments to gamma after selecting a profile) In addition to detailing alterations to the Color Management and Gamma tabs of the Preferences dialog to accommodate these changes, this chapter offers an in-depth look at the workings of Nikon CMS. Nikon Color Management - 23 - How Nikon CMS Works When image data are passed from an input device, such as a scanner, to an output device, such as a monitor or printer, color management ensures that the image displayed on the output device "looks the same" as the original. [. . . ] Preview gamma defaults to a value of 1. 8 on the Macintosh, 2. 2 on Windows computers. To choose a setting suited to your monitor, adjust the value so that the patterns of gray lines and dots above the slider match in density. Gamma can be set by entering a value directly into the text box or by moving the slider. When making this adjustment, set the resolution on your monitor to a low value such as 640 × 480 and sit as far away from the monitor as possible. [. . . ]
