Work Solidly.—Work in body color, and lay on your paint fully and freely. In getting an effect of light, don't be afraid of contrast either of value or of color. Paint loosely; get the vibration which results from half-mixed color. Don't flatten out the tone. Load the color if you want to. In twenty years you will wonder to see how smooth it has become.
Freedom and breadth give life to a sketch. Don't work close to your work. Don't bend over it. Use plenty of color, large brushes, and strike from the shoulder.
CHAPTER XXVII
THE STUDY
The qualities which make a good study are the reverse of those which make a good sketch. In the sketch all is sacrificed to the effect, or to the one thing which is its purpose. The study is what its name implies, and its purpose is not one thing, but many. In a study you put in everything which may be valuable. You store it with facts. You leave out nothing which you wish to put in. It is all material. You can take and leave in using it afterwards, as you could from nature. Of course every study has some main intention, but you must take the trouble to give everything that goes to the making of that.
A study is less of a picture than a sketch is. For unity of effect is vital to both a sketch and a picture. But this quality is of no essential value in a study—unless it be a study of unity. For you can make a study of anything, from a foreground weed to a detailed interior, from a bit of pebble to a cavalry charge.
But in a study of one thing you concentrate on that thing, you deliberately and carefully study everything in it, while in a sketch you work only for general effect. The study is the storehouse of facts to the painter. By it he assures himself of the literal truths he needs, collecting them as material in color or black and white, and as mental material by his mental understanding of them, only to be gained in this way.
In making a study you may work as long as you please, timing yourself by the difficulty and size of the thing you are studying. A study of an interior or a landscape may occupy a week or two; one of a simple object for some detail in a picture may be a matter of only a few hours. But in any work of this kind you should be deliberate, and remember that what you are doing is neither a sketch nor a picture, but the gathering of material which is to be useful, but which can be useful only so far as it is accurate.
