• Radius is the number of pixels around the edge that are affected. Higher radius Note:
values result in softer edges and lower values result in sharper edges.
• Smart Radius automatically adjusts the radius for hard and soft edges found in It might help to work

• Smooth reduces the number of points that make up your selection and, as the use the Zoom and Hand

• Feather softens the selection edge, resulting in a transition that does not have
a hard edge (in other words, blends into the background). You can feather the
selection up to 250 pixels.
• Contrast is the degree of variation allowed in the selection edge. Higher Contrast
values (up to 100%) mean sharper selection edges.
• Shift Edge shrinks or grows the selection edge by the defined percentage (from
–100% to 100%).
• Invert reverses the mask; selected areas become unselected and vice versa.
