My studio can be lighted from either side; but the "light of lights" is the north one, and that is a large fixed window 11 by 9 feet with a single slope of two and a half feet in the height; that is, two and a half feet out of the perpendicular at the top, with no other top light and no perpendicular side light. With this light I do all ordinary work. I can work round the light from one side of the room to the other, as under a mammoth skylight, without using either blind or reflector. If I want Rembrandt effects I have only to open a shutter on the south side, and let in subdued sunlight. That at once becomes the dominant light, and the north light illumines the shadows. The bottom of the north light is three feet from the floor. The advantages of this form of studio are these. It is cool, because no more light is admitted than is absolutely necessary. It is neat, because no rag-like curtains are hanging about. It is clean, because there is nothing to collect dirt. It is dry, because the pitch of the roof renders leakage impossible. It is pleasant to the sitter, because of these desirabilities, and that the light is not distressing. It is agreeable to the operator, because the work is easy and everything is comfortable.
