ADVANCED SCANNING
This section covers the advanced scanning tools in the DiMAGE Scan Utility. The basic scanning section on pages 28 through 35 should be read before continuing.
Setting scanner preferences
Click the preferences button in the main window to open the preferences dialog box. Select preferences options to customize scanner operations.
Exposure control for negatives: autoexposure adjusts the scan to compensate for the density of the negative. The manual setting uses a fixed exposure regardless of the density of the film. Manual exposure can show the exposure difference in a bracket series. When using AE lock or AE area selection with negatives (p. 53), the auto function must be selected.
Auto-expose-for-slides check box: to use autoexposure when scanning slides. Since the density range of slides is relatively uniform, adjusting the expose for each slide is usually unnecessary. However, when scanning an underexposed or overexposed slide, the
autoexposure system can compensate for the unusual image density. When using AE lock or AE area selection with slide film (p. 53), the auto-expose-for-slide box must be checked.
Autofocus-at-scan check box: this option activates the autofocus function during the prescan and final scan. When using Auto Dust Brush or Digital Grain Dissolver, the use of autofocus is recommended. The autofocus function increases the scanning time. When making an index scan with the APS holder or a quality index scan with the 35mm Film Holder, the scanner only focuses on the first frame.
Close-utility-after-scanning check box: this option closes the DiMAGE Scan Utility after the final scan when using the scanner with an image-processing application. Activate this function when individual images will be scanned and then processed or retouched in another application. Uncheck the box when multiple images need to be scanned before retouching.
Eject/rewind holder check box: this option ejects the film holder or rewinds the optional APS adapter after the final scan.
