The artists in this showcase are actively engaged in practices that expand what photography can be. Some show us that the essence of photography, drawing with light, does not require a camera or even a print. Others have used the medium in joyful and emotive ways with visual layering to obscure details while embedding meaning. Additionally, from Man Ray to A.I. we have a very interesting selection of book reviews from PhotoBook Journal featuring artists who are also expanding our ideas about photography.
