Drawing Masks Using the Freehand Mask Tool

This section describes how draw a freehand mask. Like the Paint Stroke tool, the Freehand
Mask tool allows you to create a shape in one movement, rather than drawing the shape
in a point-by-point fashion (like a Bezier or B-Spline shape). For best results, use a stylus
and tablet when using the Freehand Mask tool. For more information on drawing masks,
see

• To change the blend mode of the mask before it is drawn, use the Mask Blend Mode

outward, while negative values feather the shape inward.

• If using a tablet, touch the stylus on the tablet to begin drawing the mask in the Canvas.
