Heads (not “faces”; important to always be aware that facial features rest on a rounded, not flat, surface.) On a hat-display plastic head and/or on a hard-boiled egg, draw the vertical center line of the face and horizontal construction lines that show the eye-line (at the center, 1/2 of egg), bottom of the nose and the mouth. Illustrate by tilting the egg or dummy to show how these three diagrammatic horizontal lines, although they curve, ALWAYS STAY PARALLEL TO EACH OTHER and ALWAYS perpendicular to the center vertical. As the center axis goes, so goes the rest.
Post as many copies of master drawings and photographs of heads as you can find. On each, draw these same construction lines that illustrate how the lines curve when the head looks up or down.
DEMONSTRATION: Fingers in the ears trick: all put your fingers in your ears and then look way up and way down. Why don’t your fingers move when your whole head does? Do two quick drawings using diagrammatic structures like you drew on the egg, while explaining how you construct them. Front and profile, no model. (See homework #7) Review: lines curve on a rounded surface when tilted; photos of heads with these lines show that. (Hint: easy to find eye-line curve if drawn from the top of one ear to the top of the other, PASSING OVER THE CENTER OF THE EYE, curving it always, up or down, unless seen straight on. Likewise find the nose-bottom on the curve between the bottoms of the ears.) If you don’t find the descriptive lines for eyes, nose and mouth from their underlying construction, you’re guessing---and that’s harder. Always use simplest shapes to start. Draw eyeball circles on the eye line, making lid-lines that start on this line and curve as they pass over the round eyeball surface: thus, the almond shape. Sketch a triangle for the nose bone, a cartilage shape for the tip, and flaps connecting to the cheeks on either side: this produces an accurate three-part wavy line that defines the bottom of the nose. Draw a mouth line that follows the curves of a real mouth opening. Lips are mainly color, so if lines are used to show their form, go VERY lightly. Ears are between the eye line and the bottom of the nose. In profile: the upper lip starts under the nose NOT at its back corner; the eye is not set at the bridge of the nose, but is much further back. The ear is further back than you think.
STUDENTS: (can take turns posing for each other today)
Beginning poses, moving the head every which way, last only long enough to draw these construction lines: general shape of the skull and jawbone, one line for center axis, lines perpendicular to it that locate eyes, bottom of nose, mouth and ear shapes. Note carefully how the center line can slant and horizontal lines MUST curve, but they never change their relation to each other since they are fixed on the same surface.
2. When all get step #1, lengthen poses for more time to construct facial features with more descriptive detail. BUT ALWAYS START EACH DRAWING WITH THE SAME SIMPLE CONSTRUCTION LINES.
3. A longer pose, about 15-20 minutes to try to construct and describe more accurately. (Instructor or visitor can pose now so all can draw.)
HOMEWORK: (#7) Self PORTRAIT in a mirror or some one else, front view. CONSTRUCT as in class, from the inside structure to outer form. Look for particular characteristics of your subject. EVERY SHAPE OR CONTOUR YOU SEE IS THE RESULT OF STRUCTURE. The descriptive lines/tones you use define this.
