 ''Dali Atomicus, Philippe Halsman, 1948.'' This version of the photograph shows an element missing in the final print: the hands holding the chair. Also, the final print contains one of Dali’s paintings (“Leda Atomica”) in the frame on the easel.

Use the Layers panel pulldown menu to choose New Group from Layers… and name the group manipulations. Now the nondestructive layers are grouped into one folder. The folder can be collapsed or expanded using the small sideways triangle on the left side of the folder icon in the Layers panel.

Shape layers can be moved with the Move tool and they appear in the Layers panel as an overall path of color with a vector mask defining where the color is applied and where it is hidden, based on the way the shape was drawn.

 Now we will blend the edges of the mustache using the Paintbrush tool on the layer mask. This will make the mustache appear more realistic on the cat’s face. Click on the Paintbrush tool. Load black into the foreground color. Black will be used on the mask to hide parts of the layer content. Use the Options panel to set the opacity to 70%. Use a big, soft brush. We set our brush at 30 pixels and 0% hardness. Trace just around the edges of the mustache with the edge of the Paintbrush tool brushing against the edge of the mustache.

 Masks define which areas are visible and which image areas are invisible. Masks do not delete image areas (this is why we have classified this as “non-destructive”), they simply are used to hide or show parts of images. Since masks are either hiding or showing image areas (or partially showing), they operate in black and white and create transparency with shades of gray.
