In the first half of the twentieth century, Man Ray was responsible for making the photogram an art form.  Laszlo Moholy-Nagy also did some innovative work in the form. This is one of the first techniques I learned in the courses I took in darkroom photography. The possibilities entranced me and I began to view this art form in a new way. I've taught several workshops in the manipulation and technique of this area of photography, and sold my photograms in galleries.
