• Object Aware mode is betters suited for selecting fine detail such as hair on
complex backgrounds.
Edge Detection options:
• Radius is the number of pixels around the edge that are affected. Higher radius
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
the border region. You should turn off this option if your selection area has all
hard edges or all soft edges, or if you prefer to manually control the Radius.
Global Refinements options:
• Smooth reduces the number of points that make up your selection and, as the
name suggests, makes a smoother edge. You can set smoothness from 0 (very
detailed selection) to 100 (very smooth selection).
• 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.
