Purpose: Students will determine where values change when light moves over an uneven surface by using a range of gray values to paint the different values in a realistic self-portrait.
Process:
You will get one copy of your self-portrait. With tracing paper and the aid of the light box or a window, trace the edges of the shapes of the different values you see.
This is will take a while. Please look carefully and find all the changes in value. In some cases, you may need to improvise value changes (like separating you chin from your neck).
On the tracing paper, assign each value shape the number 1 - 6, with 1 being the lightest and 6 the darkest value. (if necessary, use your painted value strips to help assign correct values)
Make a “sandwich” in this order: acetate, 8.5” x 11” tracing paper drawing, folder(to keep it stiff) and enough tape along the edges to tack it all together (a small piece will do).
Your drawing and acetate will go on the left side and your photo will be taped to the right side. See example.
As you cover the acetate sheet it will become harder to see the drawing and shapes underneath.
Start with your eyes, then move into the other features and areas of your face, doing the hair, clothes and background last.
You will have your photo for reference if you need help with assigning values to what you see.
If you make a mistake, just let the paint dry and then paint the appropriate value on top.
When complete, mount it onto a clean sheet of tagboard or paper, neatly write your name on the front and work on the assessment.
