Chapter CLXXVII

Chiaroscuro, to use untechnical language and to speak of it as it is employed by all the schools, is the art of making atmosphere visible and painting objects in an envelope of air. Its aim is to create all the picturesque accidents of the shadows, of the half-tones and the light, of relief and distance, and to give in consequence more variety, more unity of effect, of caprice, and of relative truth, to forms as to colours. The opposite conception is one more ingenuous and abstract, a method by which one shows objects as they are, seen close, the atmosphere being suppressed, and in consequence without any perspective except the linear perspective, which results from the diminution in the size of objects and their relation to the horizon. When we talk of aeriel perspective we presuppose a certain amount of chiaroscuro.

CLXXVIII

A painter must study his picture in every degree of light; it is all little enough. You know, I suppose, that this period of the day between daylight and darkness is called "the painter's hour"? There is, however, this inconvenience attending it, which allowance must be made for--the reds look darker than by day, indeed almost black, and the light blues turn white, or nearly so. This low, fading light also suggests many useful hints as to arrangement, from the circumstance of the dashings of the brush in a picture but newly commenced, suggesting forms that were not originally intended, but which often prove much finer ones. Ah, sometimes I see something very beautiful in these forms; but then I have such coaxing to do to get it fixed!--for when I draw near the canvas the vision is gone, and I have to go back and creep up to it again and again, and, at last, to hold my brush at the utmost length of my arm before I can fix it, so that I can avail myself of it the next day. The way to paint a really fine picture is first to paint it in the mind, to imagine it as strongly and distinctly as possible, and then to sketch it while the impression is strong and vivid.

I have frequently shut myself up in a dark room for hours, or even days, when I have been endeavouring to imagine a scene I was about to paint, and have never stirred till I had got it clear in my mind; then I have sketched it as quickly as I could, before the impression has left me.
