Excerpt from Light and Shade: And Their Applications Inspired by a conviction that there is much more to the art and science of lighting than is commonly practised, I began, several years ago, a study of the appearances of objects. Attention was naturally directed toward those factors which influence light, shade, and color, because vision is accomplished through the distinction of differences in brightness and color. In other words, the aim throughout the study has been to unearth the fundamentals of lighting. It early became evident that the problem of lighting, as affecting the appearances of objects, could be divided into two parts, namely, the considerations of the quality and of the distribution of light. The former chiefly affects color and the latter, light and shade. Color has been treated in a separate volume and, insofar as lighting, vision, and the appearances of objects are concerned, this book is a companion to the preceding one. It has been difficult to transmit to others much of the data that have been garnered from observations and experiments. One of the greatest difficulties is encountered in illustrating the discussions, owing to the extreme limitations of the photographic process as compared with the eye - the recording apparatus of prime importance in the study of light and shade as attempted here. I am unaware of the existence of any treatise in which a general analytical discussion of light and shade has been presented, therefore I believe this book will be helpful in many arts.
