Condensing the entire content of a book into a single photo, Doug Keyes photographs each page onto a single piece of film to give the impression of knowledge stacking up over time. Called "Collective Memory," the series, was recently awarded a Juror’s Choice Award through the Center (formerly the Sante Fe Center for Photography).

The images retain the physical identity of the book itself and the final photograph is printed so that the size of the book in the picture is true to the size of the original book. His style of multiple exposure photography has since found its way into the works of younger and critically acclaimed artists such as Indris Khan.
