Step 5. The Highlight Areas To carry out this stage the enlarged still should be scrutenized and a study made of the highlight (or shine areas) on the face. As we proceed through further stages of the process we shall determine for each area the light value (or shaddow intensity) we think exists on each part of the face. On a scale of 1 to 10 the Highlight Areas represent 1 on this scale and will be represented on the final drawing by a white area. The highlight areas are only added with a blue pencil and cross hatched in blue also. This is done so that you can identify the areas to be left white when you are putting in the vertical shading in the next stage.
Take a look at the 'man in the top hat'. See how these highlight areas are treated and how they indicate high shine areas. With them the face appears more three-dimensional.                    Sometimes the photograph will not show a highlight area(s). In that case it will be necessary to imagine where it would exist. Consider a balloon as the head you are drawing. The beam from the flashlight would represent the light coming from a window, the sun, or some other light sourse and the reflection on the balloon would be the 'highlight area'. Consider the eyes as smaller balloons.
This concludes Step 5. The Highlight Areas
