Photo Obscura: The Photographic in Post-Photography discusses the profound transformation of post-photography. It argues post-photography is not merely a trend but a significant movement that redefines photography by integrating it with emerging technologies and creative practices, resulting in works that may not even resemble photographs but still retain a photographic influence. It is structured around various themes, including AI-generated images, the intersection of digital and physical art forms and the changing relationship between visual representation and perception. Drawing on photo history, media studies, visual studies, art history and the digital humanities and through discussions of specific artworks and artists, it provides insights into how post-photography continues to evolve, offering new ways to understand, define and engage with the photographic image in the digital age. It highlights the influence of digital culture, where the abundance of images and information has led to novel approaches in art that question the very nature of photography, truth and reality. Still, it maintains that despite this radical shift, photography's influence remains central, even when hidden or abstracted in the final work.
