Adjustment layers are also layer masks, as
indicated by the mask icon to the left of the layer
thumbnail. When an adjustment layer is active, the
foreground and background colors default to
grayscale values. By painting the adjustment layer,
you can apply the adjustment to just portions of
the underlying layers.
