The Practice and Science of Drawing

by Harold Speed

First draw in the outlines of the masses strongly in charcoal, noting the shapes of the shadows carefully, taking great care that you get their shapes blocked out in square lines in true proportion relative to each other, and troubling about little else. Let this be a setting out of the ground upon which you will afterwards express the form, rather than a drawing—the same scaffolding, in fact, that you were advised to do in the case of a line drawing, only, in that case, the drawing proper was to be done with a point, and in this case the drawing proper is to be done with a brush full of paint. Fix the charcoal well with a spray diffuser and the usual solution of white shellac in spirits of wine.

Taking raw umber and white (oil paint), mix up a tone that you think equal to the half tones of the cast before you. Extreme care should be taken in matching this tone. Now scumble this with a big brush equally over the whole canvas (or whatever you are making your study on). Don't use much medium, but if it is too stiff to go on thinly enough, put a little oil with it, but no turpentine. By scumbling is meant rubbing the colour into the canvas, working the brush from side to side rapidly, and laying just the thinnest solid tone that will cover the surface. If this is properly done, and your drawing was well fixed, you will just be able to see it through the paint. Now mix up a tone equal to the highest lights on the cast, and map out simply the shapes of the light masses on your study, leaving the scumbled tone for the half tones. Note carefully where the light masses come sharply against the half tones and where they merge softly into them.

You will find that the scumbled tone of your ground will mix with the tone of the lights with which you are painting, and darken it somewhat. This will enable you to get the amount of variety you want in the tone of the lights. The thicker you paint the lighter will be the tone, while the thinner paint will be more affected by the original half tone, and will consequently be darker. When this is done, mix up a tone equal to the darkest shadow, and proceed to map out the shadows in the same way as you did the lights; noting carefully where they come sharply against the half tone and where they are lost. In the case of the shadows the thicker you paint the darker will be the tone; and the thinner, the lighter.

When the lights and shadows have been mapped out, if this has been done with any accuracy, your work should be well advanced. And it now remains to correct and refine it here and there, as you feel it wants it. Place your work alongside the cast, and walk back to correct it. Faults that are not apparent when close, are easily seen at a little distance.

I don't suggest that this is the right or only way of painting, but I do suggest that exercises of this description will teach the student many of the rudimentary essentials of painting, such elementary things as how to lay a tone, how to manage a brush, how to resolve appearances into a simple structure of tones, and how to manipulate your paint so as to express the desired shape. This elementary paint drawing is, as far as I know, never given as an exercise, the study of drawing at present being confined to paper and charcoal or chalk mediums. Drawing in charcoal is the nearest thing to this "paint drawing," it being a sort of mixed method, half line and half mass drawing. But although allied to painting, it is a very different thing from expressing form with paint, and no substitute for some elementary exercise with the brush. The use of charcoal to the neglect of line drawing often gets the student into a sloppy manner of work, and is not so good a training to the eye and hand in clear, definite statement. Its popularity is no doubt due to the fact that you can get much effect with little knowledge. Although this painting into a middle tone is not by any means the only method of painting, I do feel that it is the best method for studying form expression with the brush.

But, when you come to colour, the fact of the opaque middle tone (or half tone) being first painted over the whole will spoil the clearness and transparency of your shadows, and may also interfere with the brilliancy of the colour in the lights. When colour comes to be considered it may be necessary to adopt many expedients that it is as well not to trouble too much about until a further stage is reached. But there is no necessity for the half tone to be painted over the shadows. In working in colour the half tone or middle tone of the lights can be made, and a middle tone of the shadows, and these two first painted separately, the edges where they come together being carefully studied and finished. Afterwards the variety of tone in the lights and the shadows can be added. By this means the difference in the quality of the colour between lights and shadows is preserved. This is an important consideration, as there is generally a strong contrast between them, the shadows usually being warm if the lights are cool and vice versa; and such contrasts greatly affect the vitality of colouring.

Try always to do as much as possible with one stroke of the brush; paint has a vitality when the touches are deft, that much handling and continual touching kills. Look carefully at the shape and variety of the tone you wish to express, and try and manipulate the swing of your brush in such a way as to get in one touch as near the quality of shape and gradation you want. Remember that the lightest part of your touch will be where the brush first touches the canvas when you are painting lights into a middle tone; and that as the amount of paint in the brush gets less, so the tone will be more affected by what you are painting into, and get darker. And in painting the shadows, the darkest part of your stroke will be where the brush first touches the canvas; and it will gradually lighten as the paint in your brush gets less and therefore more affected by the tone you are painting into. If your brush is very full it will not be influenced nearly so much. And if one wants a touch that shall be distinct, as would be the case in painting the shiny light on a glazed pot, a very full brush would be used. But generally speaking, get your effects with as little paint as possible. Thinner paint is easier to refine and manipulate. There will be no fear of its not being solid if you are painting into a solidly scumbled middle tone.

Many charming things are to be done with a mixture of solid and transparent paint, but it is well at first not to complicate the problem too much, and therefore to leave this until later on, when you are competent to attack problems of colour. Keep your early work both in monochrome and colour quite solid, but as thin as you can, reserving thicker paint for those occasions when you wish to put a touch that shall not be influenced by what you are painting into.
