Painting Portraits: Principles

Portraits have been painted for many reasons, to:

1. Achieve a likeness of the sitter's features.

2. Preserve the identity of someone for future generations, particularly before the advent of photography.


3. Create a souvenir, a loyal remembrance of someone now absent or dead.

4. Establish a public image, emphasizing the sitter's status, fashionable looks or personal qualities.

5. Record the artist's response to the living presence of the subject.

6. Represent the essential dignity or nobility of the human subject.

7. Recreate in a contemporary setting the norms of classical portraiture.

8. Explore the personality, psychology or inward qualities of the sitter.

9. Develop or extend the necessary painting skills.

The aims are far from exclusive, and portrait paintings today will be balancing many of these aims against the fee and expectations of the client.
Painting a Portrait: Some General Advice

Most portrait artists begin with drawings of the sitter. These do not supersede photographs, but are generally preferred as the very act of drawing requires the artist to study and understand what he is seeing. Nonetheless, there can be problems. Some drawings will come off straight away, but many only after a great deal of effort, and on occasions nothing seems to give a likeness. For that reason, some painters, particularly the more experienced, begin immediately on the oil portrait. By moving from general appearance to telling details they avoid producing a photographically correct but facile/bland/unilluminating facsimile of the subject. Some general hints:

1. Use the appropriate medium in preliminary work: pencils for a small and/or detailed sketch, chalks or conté for the broader sketch.

2. Ensure the lighting helps to give strength, solidity and character to the face. It is very difficult to capture a full face likeness if the lighting and features are such that the features are not tightly organized by structure. Eyes and mouth that 'float' in a soft woman's face where you cannot put muscles, wrinkles and shadows are particularly difficult. Avoid full face if you can.

3. Never make the face full-size. Two-thirds is the normal limit and half-size is safer. Too large a paper or canvas size leaves wide spaces which are difficult to fill, and in which it is difficult to place features accurately.

4. Closeness to model is important. Many expressive details of eye folds and mouth are lost a few feet further out.

5. It's usually best to block in the broad tonal or structural masses and then follow in detail with the eyes and nose. The triangle between eyes and tip of nose is a useful reference.
Portraits: Painting on a Dark Ground

Solomon {5} suggests these steps for portrait painting:

1. Make an accurate sketch in charcoal. Ensure this is correct.

2. Model tones only in turps-thinned raw umber and white.

3. Repeat stage 2 several times until modeling is correct. Each attempt should completely but thinly cover the previous. Pay attention to hard and soft edges, skin over bone and pulpiness elsewhere. Tone should be appreciably lighter than intended result dark grounds tend to absorb mid-tones and darken with age.)

4. Dry thoroughly.

5. Paint shadows in a mixture of Indian red and black, highlights with stiff white, and intermediate tones with a mixture of these colors modified with a cobalt or a very little chromium oxide green.

6. Dry thoroughly.

7. Glaze and/or scumble this grisaille with red and yellow pigments, either in oil, or oil and glazes mixed.
Portraits: Painting on a Toned Ground

The following approach is more general, and emphasizes the need to a. work out everything in advance and b. undertake oil sketches to solves problems as they arise.

1. Prepare ground properly: absorbent if you are using much medium with paint, less absorbent if you're using glazing approach. Grays, greens, pinks, browns and buffs colors are best, all pale.

2. Decide composition beforehand, either by roughing out in charcoal or by tonal drawings.

3. Work out palette prior to painting anything, and decide in this order: skin tones, then hair, then clothes and finally background. Adjust tone/hue/purity of color in clothes as necessary. You may need to make many oil sketches to harmonize everything.

4. Use lateral frontal lighting. Shadow pattern should aid composition.

5. Ensure movement of body does not follow that of head.

6. Make background some neutral color, not necessarily darker than shadows of head.
Portraits in Oil: Specific Hints

There is no "correct" approach, but many authorities suggest something like this:

1. Paint shadows to define broad structure, starting with nose.

2. Lower value in lower half of lighted area to help highlights above.

3. Make muzzle area the same color as rest of flesh but cooler.

4. Add touch of color where shadow meets light.

5. Try Venetian red as alternative to raw sienna which loses intensity with white. Paint hands etc. with these two colors and white.

6. Use cadmium colors for fair complexions, and earth colors for swarthy.

7. Shadows should be similar to background colors.

8. Add background colors to flesh tones to make area recede.

9. Tonal range of hair (light to dark) is often that of eye (highlight to pupil).

10. Highlights pick up structures and have to end on them.

11. Start with shadow areas. Cadmiums with black/cobalt blue/ultramarine and umber make good shadows. Deepen shadows if face lacks structure.

12. Break the face into planes, assign tones of one hue to these planes and paint them simply.

13. Warm skin areas always have a little cool color, and vice versa. But keep the light areas and the shadows distinct.

14. Thick flesh areas are warm and bone areas are cool.

15. Bring cheeks and chin forward with warm colors

16. Create warm backgrounds by taking shadow color and both lighten its value and weaken its intensity/purity.

17. Create cool background by choosing the cooled gray color that will represent the turning planes of your object. Cool with raw or burnt umber or with a little cobalt blue.

18. Don't let backgrounds overpower subject: make them more neutral to make subject come forward.
Portraits: Palette

Many mixtures are recommended, but it's essential not to mix more than three pigments plus white if brilliancy is to be retained. A little blending is acceptable but much better is to apply patches of paint with flat or filbert brushes and leave alone. Remember that shadow areas are an extension of the lit side, so use the same ingredients but vary proportions slightly.

Abbreviations in the mixtures that follow are:

Titanium White = W Cad. Light Yellow = y Cad. Yellow = Y Cad. Light Red = r Cad. Deep Red = R Cobalt Blue = b Ultramarine = B Viridian = V Raw Sienna = s Burnt Sienna = S Raw Umber = u Burnt Umber = U Light Red = L Yellow Ochre = O Phalo Blue = P Permanent Rose = M Naples Yellow = N Venetian Red = E

These are some recommendations in books devoted to the art of portraiture.
