I am making a mask to hide shadows on a face. I am using a MacBook Pro running os 11.6. I am doing the following steps: 1) add new fill layers from layers menu 2.Invert the mask 3 change to brush (b) 4 opacity 100, flow 100, hardness 0% 5 change color to white 6 When I go to paint on fill layer, brush puts down white on image instead of covering shadow on face so it is hidden.
