The Auto button 44 Microtek Scanner User's Guide (PC version) Color Correction / DCR This tool applies a generic color correction profile to your images to give it accurate, lifelike color. However, if you have Microtek's DCR color calibration and correction system installed, the Color Correction button will override the generic color profile and apply DCR to the image. A generic color profile is provided with the scanning software to correct the minor color shifts that occur invariably with scanners. To achieve optimal color correction, however, you need a true color calibration and correction system like Microtek's DCR, or Dynamic Color Rendition, developed expressly for this purpose. DCR creates an industry-standard color profile matched to your scanner, so that colors in your scanned image are adjusted to their optimal levels. DCR comes standard on certain ScanMaker models and is available as an option on other models. To obtain DCR, call Microtek Sales at 800-654-4160. The Color Correction button is turned on by default, but it can be turned off by clicking on the button again. Color Correction will be dimmed in the following instances: · If image type is set to billions of colors, any grayscale setting, line art, or halftone. · If the scan material type chosen (in the Scan Material command, Preferences menu) is Negative.

Take note of the following: · When you click on an image-enhancement tool, a dialog box called the Advanced Image Enhancer (AIE) appears. The AIE dialog box lets you view changes to image enhancement in real time. The AIE dialog box has two thumbnails -- providing you with "before" and "after versions of an image. Although you can use all the image-enhancement tools, you don't need to use every one of them to achieve a great image. Perhaps all that's needed is a change in the shadows or gamma curve. Try experimenting with the tools to see which one provides optimal results. The effects of the image-enhancement tools are cumulative. This is important because the cumulative effects will affect the image in a way that's totally different than if only a single image-enhancement tool was used. Example: If you increase brightness in an image (through the Brightness Contrast and Exposure tool) and then modify the gamma curve of the image (through the Curve tool), the image will have both brightness and curve changes. · · The Advanced Image Enhancer dialog box The kind of screen you see is indicated by the selected imageenhancement tool. Above is the Brightness Contrast and Exposure screen. Below is the Filters screen.
