What the Image Enhancement Tools are
The image-enhancement tools are an integral part of ScanWizard, and they let you adjust the
characteristics of your image such as brightness and contrast right from within ScanWizard.
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 enhance-
ment in real time. The AIE dialog box has two
"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.
