Using Image Controls

The Image Controls available when you choose the icon let you adjust the following image settings:

Brightness changes the intensity of light

Contrast determines the gradation between highlights and shadows

Highlight adjusts the lightest areas

Shadow adjusts the darkest areas

Sharpness adjusts the focus

Threshold adjusts the point at which the gray values change to either black or white. This option is available only when the Pixel Depth setting is Black & White and the Halftone setting is None in the Image Type dialog box. When Threshold is available, the other image control settings are not available.

Note:

The ES-300C scanner does not support Contrast, Highlight, Shadow, Sharpness, and Threshold settings.

Follow these steps to use the Image Controls:
