ScanWizard Pro is an advanced scanner controller program that provides many powerful, professional-level features for scanning. One important feature of ScanWizard Pro is that it lets you work in the LCH color space, which is based on the LCH (Lightness, Chroma, Hue) model of colors. The LCH model is a more intuitive way of editing and working with colors because it defines colors the way we understand them-- based on the properties of brightness (how light or dark a color is), saturation (how rich or dull a color is), and hue ("red" as opposed to "blue"). Another important function of ScanWizard Pro is the batch scan feature, a separate but integrated program that lets you create and manipulate specific "contexts" or batches of jobs. With Batch Scanning, you can lay out your jobs beforehand, make adjustments to each scan, then start the scan when you are ready. The result? A tremendously improved workflow and savings in time, with the additional advantage of being able to call up the various "contexts" or batch jobs when required. ScanWizard Pro is also ColorSyncTM-savvy, allowing you to use standard ICC color profiles for accurate color matching when outputting your images. A Powerful New Software With ScanWizard Pro, you can achieve a new level of efficiency in scanning. The many powerful tools of the program work together to help you obtain the superior color images you need, as well as provide you with the flexibility to adjust or improve the images as needed. As you become increasingly familiar with the program, you will also see how ScanWizard can open up a whole new vista for organizing your workflow and boosting your scanning productivity in as many ways as your creative imagination will allow.

ScanWizard Pro for Macintosh Users Guide About this Manual This manual provides basic information on the program and sketches out a variety of scenarios that illustrate ScanWizard Pro's versatility and how best to use the program for specific scanning tasks. For a more detailed listing of individual features, please refer to the companion Reference Guide included in your documentation package. ScanWizard Pro for Macintosh Users Guide 9 English English 10 ScanWizard Pro for Macintosh Users Guide 2 Getting Started This section of the manual describes the two modes of operating ScanWizard Pro: 1. The Scan mode, in which ScanWizard Pro is "acquired" from an image-editing software program like Adobe Photoshop; and 2. The Batch mode, which is launched from the Apple menu and is used to process batch scans. Using the Scan mode The Scan mode refers to launching ScanWizard Pro from an image-editing software such as Adobe Photoshop. To operate ScanWizard Pro in the "Scan" mode, launch the image-editing software of your choice. When the software program launches, go to the File menu, and choose Import or Acquire from the submenu, depending on the software you are using. This will automatically launch ScanWizard Pro, and the four major windows that form the interface of ScanWizard Pro will appear on your screen. In addition to the above, you can run the ScanWizard Pro Applet located in the ScanWizard Pro folder. The Applet is a small-sized application that will launch the ScanWizard Pro Plug-in to scan images. Using the Batch mode The Batch mode of operating ScanWizard Pro allows you to set up scans in "batches" of jobs beforehand and then lets you start the scanning process when you are ready to do so with the simple click of a button. To operate ScanWizard Pro in the "batch" mode, go to the Apple menu, and choose the Batch Scan command. For more details, refer to the batch scan scenarios and information presented in the Special Features & Advanced Scenarios section of this manual. Exiting ScanWizard Pro To exit ScanWizard Pro, go to the Preview window, and from the File menu, choose the Quit command, or press the Apple+Q combination keys on your keyboard. ScanWizard Pro for Macintosh Users Guide 11 English English Monitor selection shown here is set in ColorSync Control Panel. Color Matching features 12 Color Matching The first time you launch ScanWizard Pro, you will be prompted to perform color matching for your monitor and printer. Color Matching is an important feature of ScanWizard Pro that ensures color consistency -- from the initial input phase when an image is captured by the scanner, to the final output process when the image is output to your monitor or printer. Color Matching allows you to gain the assurance that the colors captured by the scanner are the same when they are displayed on your monitor and will be reproduced as closely as possible when they are printed. To use Color Matching: As mentioned above, you will be prompted to select color matching settings immediately after you launch ScanWizard Pro the first time. At any point in the future, you may also select color matching settings to change your color profile. To do this, go to the Preferences menu in the Preview window, and choose the Color Matching Setup command. See the Appendix section of the manual for more details. Immediately updates the Preview window image when a new setting is selected. This will reflect colors consistent with the newly selected profile. For more information on color matching, please refer to section of the manual titled More Color Matching Information in the Appendix and the Appendix C: Kodak Color Management System in the References. ScanWizard Pro for Macintosh Users Guide RGB Destination This feature lets you select the correct profile for outputting images to the RGB color space. The RGB Destination profile usually pertains to a monitor (since all monitors are RGB devices), but an RGB printer profile may also be used as a selection if the RGB color space in which you choose to work is an RGB printer. To specify the RGB Destination profile: Choose from the profiles provided by ScanWizard Pro, or choose your own profile if you have others stored on your system. CMYK Destination This feature lets you select the correct profile for outputting images to the CMYK color space. To specify the CMYK Destination profile: Choose from the profiles provided by ScanWizard Pro, or choose your own profile if you have others stored on your system. For additional CMYK profiles, please run the ICC Profile Installer from your ScanWizard Pro CD.

From the drop-down menu that appears, select your source material -whether the image being scanned is from a newspaper, magazine, or art magazine (higher-quality printing). Note: If you know the printed lpi (lines per inch) for the image, you may enter the exact number. You can measure the line screen by using a screen finder, which can be purchased from your local print shop. 6. Click the Scan button. When the image is scanned, no moiré patterns will be evident. Compare the "descreened" image to simply scanning the image with the Descreen selection set to "None", and you will see the difference in the image. The Descreen tool is used to remove "screens" or moiré patterns from appearing in images. Moirés are interference patterns that show up on your scanned images when you use previously printed matter, such as magazines and newspapers, as your source material (instead of using an original color photo or print). In moiré images, you will see these patterns emerge as a series of crosshatches or screens crisscrossing the image. In the example here, an image was scanned from a magazine, resulting in an undesirable moiré pattern. The solution: rescan the image, with the Descreen tool "On" to eliminate potential moirés from appearing in the resulting image. If you want to....

All the tools are available when you work in the default LCH color space, but a different set of tools is available when you choose to work in the Native color space. Included at the beginning of this section is a brief discussion of the LCH color model vs. the Native color model, as well as other concepts important to optimizing your workflow. The scenarios provided are based on the Advanced Image Correction tools available through the LCH color model. · The LCH Color Model · LCH vs. Native Color Mode · Workflow for Optimizing Images · Adding a Custom Setting · How to Choose the Right Image Category · Using the Dynamic Range Tool · Using the Black / White Points Tool · Using the Gradation Tool · Using the Color Cast Tool · Using the Saturation Tool · Using the Selective Color Tool · Using the Tone Curve Tool · Using the Filter Tool ScanWizard Pro for Macintosh Users Guide 27 English English 28 The LCH Color Model One of ScanWizard Pro's strengths is its ability to let you work in the LCH color space. Unlike the RGB color model, which corresponds to the color space as defined in monitors and printers, the LCH color model is a more intuitive way of working with colors, based on the values of Lightness (the "L" in LCH), Chroma (C), and Hue (H). For instance, if you wish to change the color of the sky in an image to a darker blue, your own eye -- and your own judgment -- will be the guide to making those color changes. This is easier than, say, knowing the mathematical equivalent in RGB or CMYK values that would correspond to a "dark sky blue". The LCH model, in effect, makes it easier to comprehend colors as they are couched in the terms we are familiar with: Lightness (how dark or light a color is), Chroma or saturation (how rich or dull a particular hue of green is), and Hue (the property that distinguishes, say, the color red from the color blue.) In the LCH color model, colors of equal brightness lie on a single plane of the model, as shown below. Red and green lie opposite each other on the horizontal axis, as blue and yellow lie opposite each other on the vertical axis. On the color sphere shown below, you can see how the different LCH properties play out: · · · The different hues (red, green, yellow, blue) are spread around the sphere. The chroma (saturation) for each hue increases from the center of the sphere outward, with the most saturated colors lying on the edge of the sphere. The brightness values increase from the bottom of the model to the top ScanWizard Pro for Macintosh Users Guide Selecting LCH or Native Color Space ScanWizard Pro lets you choose the color space in which you wish to edit and work with color images. · Select LCH mode if you wish to edit or correct images in terms of color perception according to the human eye, based on the properties of Lightness, Chroma, and Hue. This is the default mode. · Select Native mode if you wish to edit or correct the individual RGB / CMYK channels of an image. To switch between LCH and Native color modes, go to the Preferences | More command in the Preview window. When the More Preferences dialog box comes up, go to the Working Color Space option, and choose LCH or Native as the color mode you wish. ScanWizard Pro for Macintosh Users Guide 29 English English Workflow for Optimizing Images To prepare and optimize your images for the final scan, we recommend the use of the Advanced Image Correction tools in the sequence that they appear in the Settings window. Following this order will significantly influence the overall quality of your images. 1 Dynamic Range Manual or auto determine image density range (darkest tone to lightest tone) 2 White & Black Points Manual or auto-adjust shadow and highlight points 3 Gradation Manual or autoadjust midtones of the Lightness channel "L" Saturation Curve Adjust image saturation by manipulating the saturation curve 4 5 Color Cast Adjust gray balance by removing color cast or adjust desired cast by adding color cast Selective Color Manipulate a specific color range without affecting other colors 6 7 Tone Curve Adjust tonal distribution of each channel of a CMYK/ RGB image 8 Filter Apply a particular filter for special effects (e.g., unsharp masking to sharpen image) The sequence is the same if you are working in Native color mode. However, the Gradation, Color Cast, Saturation, and Selective Color tools (#3 to #6) will not be available. The Brightness / Contrast and Color Correction tools are offered in their place. The Brightness / Contrast and Color Correction tools are offered in the Native color mode 30 ScanWizard Pro for Macintosh Users Guide Adding a Custom Setting To the right side of each AIC (Advanced Image Correction) tool is a custom pulldown menu that features predefined settings for the AIC tool. For instance, some of these settings include Automatic or No Correction. You can also add your own image correction setting for each AIC tool. That way, you can retrieve or load the setting at any time in the future. To do this, choose an AIC tool and make the adjustments you desire to the image. Then click the Add to Menu button in the AIC dialog box. When another dialog box comes up, enter the name for the new setting. The new setting will appear in the custom pull-down menu of the Settings window for that particular AIC tool New setting appears here Click this button to add a custom setting ScanWizard Pro for Macintosh Users Guide 31 English English 32 How to Choose the Correct Image Category ScanWizard Pro provides several image categories to choose from, which can influence the auto-correction function and provide a more accurate output image. To select the correct image category, go to the Settings window and choose the option you wish from the Image Category menu. Select the image category that corresponds most closely to the image characteristics of your original. The selected image category provides a starting point of predefined settings that can be applied to your image and bring out characteristics specific to that image type. · · None: No image category conversion. Standard: An image that does not fall into any of the described below. You can also use this category for images of good quality (neither underexposed nor overexposed, with accurate color and tones). Landscape: An image with cool atmosphere with broad tonal variation and a wide hue range. Examples include natural scenery, skyline with an expanse of blue sky, mountains and fields. Portraits (Skin Tones): An image with dominant skin tones and mid-tone details present. Examples include portraits and objects with fleece- or skin-like covering. Jewelry (Gold Tones): An image featuring dominant gold / silver hues. Examples include gold and silver jewelry, silverware. Sunsets: An image with warm reddish hues or a color cast reminiscent of sunsets. Examples include scenes at dusk or twilight and images of the Grand Canyon. Metallic Subjects: An image with broad highlight and shadow details but with very narrow mid-tone details. Examples include audio equipment, TV sets, cameras. High Keys: An image with broad highlight tonal variation but with less shadow detail. Examples include snow-covered landscapes, wedding gowns, whitewashed structures. Low Keys: An image with broad shadow tonal variation but with less highlight detail. Examples include nighttime scenery, dark suits and clothing, a coal pit. Underexposed: An image with compressed tonal variation particularly in the shadow areas, characterized by an overall dark appearance typical of underexposed positive film. Overexposed An image with compressed tonal variation particularly in the highlight areas, characterized by an overall bright appearance typical of overexposed positive film. · · · · · · · · · ScanWizard Pro for Macintosh Users Guide Selecting the correct Image Category Image assigned Standard image category In the example above, an overexposed original is shown in two different image categories. Because the original was overexposed to begin with, choosing the Overexposed image category had the result of neutralizing the exposure, resulting in a better image. Image assigned Overexposed image category The same original did not fare as well when it was assigned the Standard image category (too bright overall, not enough contrast), because this image category is best used for originals of fairly good quality (sharp, neither underexposed nor overexposed) and not, in this case, for an original with flawed exposure settings. This example then shows the importance of choosing the correct image category that corresponds most closely to your original to obtain optimal results. ScanWizard Pro for Macintosh Users Guide 33 English English Using the Dynamic Range Tool The Dynamic Range tool is used to set the density capture range of the scanner and displays the density distribution (histogram) of the image to be scanned. The Auto range (default) feature automatically determines the Dmin (minimum density, lightest tone) and Dmax (maximum density, darkest tone) of the image, and sets the scanner capture range. In the example here, the original image has low contrast and a limited range of tones, as can be seen in the narrow image histogram. The solution: To narrow the scanner's range of density capture to the density range of the image (or smaller). This would then redistribute the small density range of the image to the maximum range of the scanner output, and thus restore contrast to the image. 1. Place the image to be corrected on your scanner. 2. Click the Overview button to start an overview, and you will see the image appear in your Preview window. 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view in the View menu. 4. Click the Dynamic Range tool in the Settings window. The Dynamic Range screen will appear. 5. Adjust the Dmin and Dmax values to an optimized range. To do this, move the sliders to the boundaries on both ends of the histogram. Corrected image and lightness histogram with density correction, showing a broader tonal range Original image and lightness histogram without density correction, showing narrow tonal range 6. Click OK to confirm the correction. Note: In the default Automatic setting, ScanWizard Pro optimizes density capture range automatically.

(See note on next page for additional descriptions.) By using this tool, you can manipulate an image to either bring out the highlights in a very dark image, or bring out more of the shadows in a very light image. The White & Black Points tool can also be used to neutralize the color cast in the highlight and shadow regions. In the example here, we need to set the shadows and highlights, as well as correct the color cast on both highlight and shadow regions. 1. Place the image to be corrected on your scanner. 2. Click the Overview button, and you will see the image appear in your Preview window. Original image 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view in the View menu. 4.

This helps to neutralize the color cast in the shadow and highlight areas of the image. 6. Click the Auto button. This will automatically set the optimal highlight and shadow points for the image. 7. Check the Preview box so that the image in the Preview window is updated with the latest image correction. The update is done in the background and so may take a few moments to show. 8. Click OK to confirm the correction. Image corrected with White & Black Points tool 36 ScanWizard Pro for Macintosh Users Guide Using the White & Black Points tool Use the White & Black Points tool to set the shadow and highlight points of an image, as well as to neutralize the color cast in shadow/highlight regions. In the example below, the original has a slight color cast in the shadow and highlight portions of the image. With the use of the auto neutralizing and auto adjustment features, the color cast is removed, and the shadows and highlights are remapped accordingly. 4 7 5 6 8 The shadow point is defined as the lightness value L in an image that is output as black (mapped to the Minimum Output Level), while the highlight point is defined as the lightness value L that is output as white (mapped to the Maximum Output Level). The default values of the Minimum Output Level and Maximum Output Level are L=5.0 and L=95.0, respectively. ScanWizard Pro for Macintosh Users Guide 37 English English Using the Gradation Tool The Gradation tool lets you adjust the midtones (the mid-level grays) of the lightness channel "L" of an image without altering the color itself. This is because even with changes to the luminance or lightness value, the chroma and hue values are kept constant. To prevent color images from losing saturation when adjusting the lightness, ScanWizard Pro provides a Saturation Range option. With this option, colors outside of a given chroma range are not affected by the manipulation of the gradation curve. In the example here, the original image is underexposed, with the middle tones of the image being too dark. The solution: Lighten the tones to brighten up the image. 1. Place the image to be corrected on your scanner. 2. Click the Overview button, and you will see the image appear in your Preview window. 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view in the View menu. 4. Click the Gradation tool in the Settings window. The Gradation screen will appear. Image corrected with Gradation tool Original image 5.

Click OK to confirm the correction. 7 1 0 ScanWizard Pro for Macintosh Users Guide 45 English English Using the Tone Curve Tool The Tone Curve tool is used to adjust the tonal distribution of each channel of an image. It functions very much like the Gradation tool, except that it provides additional functions to allow separate adjustments of the tones in each RGB or CMYK channel, depending on the image type. This tool is especially useful for correcting the "ink percentage" distribution (i.e., dot gain correction) in CMYK images. In the example here, the original image looks cold, with a decidedly blue-green cast to it. The solution: Increase the "ink percentage" of the yellow and magenta channels to bring out the warmer tones. 1. Place the image to be corrected on your scanner. 2. Click the Overview button, and you will see the image appear in your Preview window. 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view in the View menu. 4.
