5. We can further adjust the lighting by painting directly into the layer mask. Painting lighter values into
the mask with the paintbrush will darken areas while painting black will lighten them (within the limits
of the original levels adjustment). Figure 5-54 shows the effect of painting directly into the layer mask
with a soft round brush and the color black to pick out areas of light. The rim light along the arm in the
right-hand image was created in this manner as well as the various highlights in the arm.
6. Further details can be added by using the same technique of sampling color directly from the image and
painting into a normal layer. Figure 5-55 shows the before and after images of the head after some skin
striations and highlights have been painted in to add interest to the area.
Figure 5-54: Painting black into the layer mask will brighten areas that have been darkened. This is useful
to pick out highlights in the dark areas.
