Use the Contrast slider on the 2D View and 3D View toolbars to set the amount of shading applied to the active bitmap layer's artwork. Use it to make it easier to draw vector outlines around specific areas within an image.
To make colours more saturated, drag the slider to the left; to restore the artwork to its original sharpness, drag the slider to the right.
