Epson STYLUS SCAN 2500 User Manual page 154

Shadow:
The Shadow control allows you to adjust the darkness level
of the darkest parts of an image. You can select from 0 to 60
by moving the slider.
Click the eyedropper button beneath the slider, and the
mouse pointer changes to an eyedropper. Move the
eyedropper over the preview image, and click a dark area.
The eyedropper "picks up" the color from that area, and uses
it as the shadow for the entire image. This effect shows up
immediately in the preview image. Click Cancel to restore
the original image.
Threshold:
Available only when Pixel Depth is set to Black & White and
Halftone is set to None in the Image Type dialog box. The
scanner scans gray shades as either black or white using this
setting.
You can select from 0 (lightest) to 255 (darkest) by moving the
slider.
