[. . . ] The maximum dynamic range depends on the bit depth of the scanner model. For example, a 12-bit per (R, G, and B) color scanner may have 3. 6D in dynamic range; where a 8-bit per color scanner will have lower dynamic range. Dynamic range differs from scan materials as well. A piece of positive original can have a dynamic range up to 4. 0D, yet negative original or reflective material (picture or printed document) results a dynamic range possibly equal or lower than 2. 0D. Without optimized remapping from scanner's dynamic range to the dynamic range of the original, tonal range of the image will not be fully captured, resulting poor contrast. Automatic dynamic range setting determines the lightest tone (Dmin) and darkest tone (Dmax) of the original automatically, then captures the image with the full input tonal range of the scanner. This setting optimizes the contrast of the output image, most useful for scanning negative films. Note: Automatic dynamic range is not suitable for originals such as image contains direct light sources or specular highlights such as reflections from shining metal or bright glass surfaces, these should be kept as purely white. An automatic Dmin may generally be placed incorrectly in specular highlights, causing other highlights and midtones to be darkened. In addition, automatic Dmin/Dmax setting is not suitable for low-key and high-key images. Reference: The Settings Window 63 The Dynamic Range dialog box By default, this tool automatically determines the lightest density or tone (Dmin) and darkest tone (Dmax) of the original; then it captures the image color data (histogram area) with the full input tonal range of the scanner. This setting optimizes color balance and the contrast of the output image, and is most useful for scanning negative films. You can override the auto-settings by defining your own custom dynamic range (Dmin/Dmax) values to all or each individual RGB channels. Manual setting tools are provided in the AIC Dynamic Range dialog box shown below. "Automatic" is checked & will display to indicate auto setting is on when the Auto button is clicked Access to other AIC tools Drag sliders to define custom Dmin/Dmax settings Enter custom Dmax setting here Enter custom Dmin setting here Click to revert to the Scan Wizard Pro default setting Click to apply or revert to automatic setting (ScanWizard Pro algorithm) when dissatisfied with manual setting Click to revert to the custom setting defined right after current start up Click to save and add the current custom setting to Dynamic Range pre-set settings Observe histogram density values at cursor position as it is swept around the histogram Click to automatically apply the full range setting "Custom" is checked & will display to indicate manual setting is on when the Dmin or Dmax is manually adjusted Click to delete saved custom Dynamic Range settings (if any) from folder Click to automatically or manually balance all RGB channels Click to automatically or manually balance individual RGB channel 64 Microtek ScanWizard Pro for Windows You can also use the Eyedropper tools to define Dmin and Dmax settings. Just move the cursor toward the prescan image while the AIC Dynamic Range dialog box is on display. Notice that the cursor automatically transform itself into Black Eyedropper tool (default). The Black Eyedropper tool appears when you move cursor toward the prescan while AIC Dynamic Range dialog box is on display. Use this tool to manually define your Dmin (shadow) setting. Press Alt key to switch tool into White Eyedropper and use it to assign the Dmax (highlight) setting. Release Alt key to revert back to Black Eyedropper tool. Enable this check box to show simulated effect of the adjustment on the prescan image Reference: The Settings Window 65 White/Black Points tool For color and gray images, this tool allows you set white/black points; for lineart image, it carries out threshold adjustment feature. The White/Black Points dialog box (Color/Gray image) By default, this tool automatically determines the lightness (but not chroma and hue) of a prescan color or gray image. When the default setting fails to provide the lightness you want for your prescan, you can click the Auto button to allow the tool to analyze your prescan and then auto-clip the White and Black points of the Lightness histogram to optimize lightness of the output image. You can override the auto setting by providing your own custom clipping values in the "L" edit box for both White and Black points or . L The tool also provide option to auto-neutralize undesirable color cast in either or both highlight and shadow areas of the image. Observe Histogram Input Lightness, Pixel Counts, & % of Lightness values at cursor position as it is swept around the histogram Check to AutoNeutralize unwanted color cast in Shadow (Black) area (LCH Mode only) Check to AutoNeutralize unwanted color cast in Highlight (White) area (LCH Mode only) Click to define custom parameters (in %) for Auto Clipping, Output Levels, and Highlight/ Shadow Markers Click to apply the automatic (ScanWizard Pro algorithm) or custom clipping setup values of the prescan Access to other AIC tools Drag sliders to define custom Lightness settings Enter custom Lightness, Chroma, & Hue values for Shadow (Black) area here. C & H values are applicable only when the Shadow check box of Auto Neutralize is enabled Enter custom Lightness, Chroma, & Hue values for Highlight (White) area here. [. . . ] In the Settings window, check the "Automatic Color Restoration" option. Click the "Scan" or "Batch" button to perform scanning. Automatic Color Restoration is applied, and faded colors in the photo are restored. To use Automatic Color Restoration function: 1. 3. Mac OS X Windows XP Before After 7 Automatic Color Enhancement The Automatic Color Enhancement feature improves the contrast and saturation of an image, resulting in more vibrant colors. [. . . ]
