The Practice and Science of Drawing

by Harold Speed

The powder on a lady's face, when not over-done, is an improvement for the same reason. It simplifies the tones by destroying the distressing shining lights that were cutting up the masses; and it also destroys a large amount of half tone, broadening the lights almost up to the commencement of the shadows.

Tone relationships are most sympathetic when the middle values of your scale only are used, that is to say, when the lights are low in tone and the darks high.

They are most dramatic and intense when the contrasts are great and the jumps from dark to light sudden.

The sympathetic charm of half-light effects is due largely to the tones being of this middle range only; whereas the striking dramatic effect of a storm clearing, in which you may get a landscape brilliantly lit by the sudden appearance of the sun, seen against the dark clouds of the retreating storm, owes much of its dramatic quality to contrast. The strong contrasts of tone values coupled with the strong colour contrast between the warm sunlit land and the cold angry blue of the storm, gives such a scene much dramatic effect and power.

The subject of values will be further treated in dealing with unity of tone.

Variety in Quality and Texture

Variety in quality and nature is almost too subtle to write about with any prospect of being understood. The play of different qualities and textures in the masses that go to form a picture must be appreciated at first hand, and little can be written about it. Oil paint is capable of almost unlimited variety in this way. But it is better to leave the study of such qualities until you have mastered the medium in its more simple aspects.

The particular tone music of which we were speaking is not helped by any great use of this variety. A oneness of quality throughout the work is best suited to exhibit it. Masters of tone, like Whistler, preserve this oneness of quality very carefully in their work, relying chiefly on the grain of a rough canvas to give the necessary variety and prevent a deadness in the quality of the tones.

But when more force and brilliancy are wanted, some use of your paint in a crumbling, broken manner is necessary, as it catches more light, thus increasing the force of the impression. Claude Monet and his followers in their search for brilliancy used this quality throughout many of their paintings, with new and striking results. But it is at the sacrifice of many beautiful qualities of form, as this roughness of surface does not lend itself readily to any finesse of modelling. In the case of Claude Monet's work, however, this does not matter, as form with all its subtleties is not a thing he made any attempt at exploiting. Nature is sufficiently vast for beautiful work to be done in separate departments of vision, although one cannot place such work on the same plane with successful pictures of wider scope. And the particular visual beauty of sparkling light and atmosphere, of which he was one of the first to make a separate study, could hardly exist in a work that aimed also at the significance of beautiful form, the appeal of form, as was explained in an earlier chapter, not being entirely due to a visual but to a mental perception, into which the sense of touch enters by association. The scintillation and glitter of light destroys this touch idea, which is better preserved in quieter lightings.

There is another point in connection with the use of thick paint, that I don't think is sufficiently well known, and that is, its greater readiness to be discoloured by the oil in its composition coming to the surface. Fifteen years ago I did what it would be advisable for every student to do as soon as possible, namely, make a chart of the colours he is likely to use. Get a good white canvas, and set upon it in columns the different colours, very much as you would do on your palette, writing the names in ink beside them. Then take a palette-knife, an ivory one by preference, and drag it from the individual masses of paint so as to get a gradation of different thicknesses, from the thinnest possible layer where your knife ends to the thick mass where it was squeezed out of the tube. It is also advisable to have previously ruled some pencil lines with a hard point down the canvas in such a manner that the strips of paint will cross the lines. This chart will be of the greatest value to you in noting the effect of time on paint. To make it more complete, the colours of several makers should be put down, and at any rate the whites of several different makes should be on it. As white enters so largely into your painting it is highly necessary to use one that does not change.
