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.
