Contributed by Adam Simon / Lately I find myself wondering what impact the ubiquity of cellphone cameras is having on the practice of fine-art photography. As frustrating as it might be for the serious photographer to see everyone and their cousin constantly taking and posting pictures, one salient effect could be a rising inclination to explore the limits of what defines a photograph. There has been a resurgence of interest in photograms and camera obscura for some time now, and Joy Episalla’s current show of works labelled ‘foldtograms’ on view at Tibor de Nagy are even further removed from the idea of capturing an image.
