| Details from color wash and form painting stages of Tessa portrait |
This is the fourth in a series of blog posts detailing the process for a portrait of Tessa that I painted from life at The Ryder Studio earlier this year. Here are the first three posts:
1. Overview
2. First stages: Thumbnail Sketch, Poster Study, Preparatory Drawing
ABOUT THE FORM PAINTING TECHNIQUE
Form painting is the final stage. The values are usually a bit darker
than the color wash. Beginning with the
darker areas and working toward the light, I complete one area at a time.
Paint is specifically mixed in progressions that turn each small form
from dark to light.
When form painting, I try to use the paint fairly opaquely
and add just a touch of medium if the mixture feels stiff. I mix on my palette with my brush, usually
beginning with the darkest tone that I’ll need for the area I’m working
on. I place it on the canvas and make
adjustments if necessary. Then I mix the
next lightest step in the progression next to and touching the first. I place that on the canvas and make any
adjustments, then continue on in the same way until I reach the lightest tone
in that particular progression. I
usually lay in a base for the form in which I keep the very lightest values
slightly darker than I want them to ultimately be. Then I bring up those final values by
brushing a lighter mixture into the underlying paint.
FORM PAINTING THE
PORTRAIT OF TESSA

| Completed color wash, before beginning form painting |
I finished the color wash of Tessa on Wednesday of my 4th week. I still had a little time before the end of the session, so I decided to begin the form painting the same way that I began the color wash: with the ear.
THE EAR
 |
| Ear anatomy terms |
To get started, I carefully placed the darkest darks in the recessed concha and a few other areas bordering the ear. I then treated my paint edges in preparation for the next day-- feathering some edges with a bit of solvent; and in other places, mixing an adjacent tone to begin the transition or progression into the neighboring areas. Usually I try to resolve any edges as I go along, by painting a bit beyond them into the next area. That way, at the end of each session, the area of form painting is integrated rather than stopping abruptly with hard edges.
 |
| Ear - Day 1 |
On Thursday I finished form-painting the ear and earrings. I began the session by placing the darks in
the furrow between the helix and anti-helix; then I connected those with the dark areas I had painted the day before, by
painting the lighter anti-helix in between. I continued on with the tragus, anti-tragus, and the lower
part of the helix.
 |
| Ear - Day 2 |
I had been working around the earrings, and was now ready to pop them in—first the silver ball and then the faceted gem. I used small creamy dabs of paint to create the reflections, adjusting the contrast as appropriate for each. Next I laid in a base for the earlobe and then brushed in the light catching on each small sub-form. Finally, I finished the top of the helix.

THE JAW, CHEEKBONE, AND CHIN
On Friday I began with the shadow that runs
along the jawline and casts onto the neck. As I worked out to the underside of the chin, I shifted
toward more intense coral-colored reflected light bouncing up from the chest
and hoodie. I also painted a bit of the
blue background next to the chin and neck for color context and to fuse with
the edges of the skin.
As I moved up toward the underside of the near cheekbone, I noted that the forms under the cheekbone were catching a bit of diffuse light, but I was careful to keep the values in key so that they would not pop out too much. I continued up the cheekbone and then the chin, turning the forms from shadow into the light.
THE MOUTH
On Monday of my fifth and final week, I completed Tessa’s
mouth. I began with the chromatic darks
in the vermilion zone of her upper lip (2), and then progressed up into the skin
just past the vermilion border (3). I then
switched to the lower lip, placing the darker tones first (4) and and then turning
up into the light (5). Finally I dropped in
the highlights on the lower lip (6). Throughout
the session, I tried to focus on how light washes across the larger underlying
forms of the mouth area, rather than merely filling in a rose-colored lip-shaped outline.
I started the nose on Tuesday: first the underside, cast shadow, nostril cavities, and septum; then working up to the light on the tip and the wings. I also completed the philtrum (the vertical groove extending from the base of the nose to the cupid's bow of the upper lip) and finished the upper lip area.
THE CHEEKS
On Wednesday I began creating a nest for the eyes by painting the lower eyelids, and then I completed the cheeks. When I’m painting a form from dark to light, I also think about painting up to the next dark downturn. In this case, as I worked up from the underside of the cheekbone, before rolling all the way up to complete the lightest lights, I wanted to first (as Tony calls it) “corral” the lights by putting in the lower eyelids, which are not as light-facing and are therefore darker.
THE BROW
On Thursday, I continued to make a nest for the eyes. Getting the eyes to look right seems easier to me if I first paint the surrounding area for context, and then I can place them more accurately. The next major downward-facing plane was the underside of the brow, so I began to work around the eyebrow forms and the glabella (the area connecting nose and forehead). I also worked a little bit into the forehead and completed the bridge of the nose.
THE EYES
Eyelashes won’t achieve optical realism if each is painted
with a crisp black line. Firstly, the lashes
themselves vary in thickness and color from lash to lash, and each lash is
usually thinner and lighter at its end than it is at its root. They also tend to clump together in tapering and foreshortened shapes that curve to catch the light differently at each point. Secondly, due to the resolution of our vision
and the scattering of light, lashes visually soften and dissolve to varying
degrees into the surrounding areas of shadow and light on the skin, iris, sclera
(white of the eye), background, etc.
The sclera is called the “white” of the eye, but is usually infused with a touch of the color of the skin, blood vessels, and ambient light. It is part of a rounded form that drops in value as it receives less light.
The rim of the lower eyelid is upturned toward the
light, and is often close in value to the white of the eye but a touch pinker.
I completed Tessa's left eye that evening, and Friday morning I approached her right eye in the same way.
FOREHEAD AND FINISH
After evaluating the painting and making some final adjustments, I quickly finished her forehead and hairline at the end of the session, and the portrait was done.
I hope you've enjoyed seeing the step-by-step process for my portrait of Tessa!

THE EYES
We also had an evening session with Tessa on Thursday, and
with only one more day left of the pose, I was eager to start on the eyes. I already had the lower lids blocked in, so I
began with her left upper eyelid. These
forms are very small, but getting them to curve convincingly around the eyeball
requires careful attention to the shape and light distribution.

| Upper lid (Tessa's left eye) |
The sclera is called the “white” of the eye, but is usually infused with a touch of the color of the skin, blood vessels, and ambient light. It is part of a rounded form that drops in value as it receives less light.
Tessa’s eyes are greenish, so for the iris I used a range of
mixtures from bluish-gray to muted gold.
The border of the iris and sclera is soft rather than sharp. This is due to several factors including the
translucency of the sclera and, again, the resolution of vision and scattering
of light.
The highlight is placed on top of a base of slightly dimmer light,
which creates a soft transition from the dark tones in the pupil and the
shadow cast on the iris by the upper eyelid.
The shape of the highlight is curved as it maps to the form of the
cornea. In this pose it appears horizontally
elongated. The large bank of overhead
fluorescents creates a roughly rectangular reflection, the top of which is
truncated by the upper eyelid.
