Photogravure

For a photogravure to appear true to its subject, its negative may first have to be made backward. Henry R. Blaney shows how a photograph can be turned into a copper-plate image—and why a flawed negative can spoil the whole craft.

In the late nineteenth century, photographers and printmakers were learning to unite the camera’s image with the etched copper plate. Blaney’s practical guide begins with the negative: it must be well exposed, full of detail, and often reversed, whether by camera, mirror, prism, or other ingenious means. From there, the work moves through transparencies and sensitized materials, where light, chemicals, and painstaking judgment shape the final print. Every small defect can travel from glass to plate, while careful retouching can strengthen the image. How does a fragile photographic negative become a print with depth, precision, and permanence?
