Editing masks

When you edit a mask, you change either its area or the degree of masking. For example, painting over an object to mask it changes the area, whereas applying a gradient fill changes the degree of masking.

You can invert the transparency of a mask, so that black pixels become white, white pixels become black, and shades of gray become their mirror value, which is the maximum value (255) minus the current value.

You can use a gradient, pattern, or texture mask to create interesting effects. A gradient mask varies the opacity of an image from fully hidden to fully transparent by fading the image in or out. A pattern or texture mask varies the image opacity in a repeated pattern throughout the image.

You can edit the layer properties of a mask, such as the name, visibility, or opacity. For more information, see Working with layers.
