In our daily lives we are bombarded with photographs. They leap out at us from the pages of our newspapers and magazines, from billboards on the highway, from junk mail that arrives every morning. The sheer number of pictures to which we are exposed is overwhelming. We cease to take them in. Artists who choose the camera as their means of expression risk being absorbed unless their statements have sufficient impact. The content of a photograph is almost always determined at the time of exposure. But it can be strengthened and refined or even destroyed in the darkroom. This potential for success or failure makes darkroom technique of prime importance to any photographer.
– Eleanor Lewis, in the preface to Darkroom, published by Lustrum Press in 1977
