Book excerpt: The real world is full of cameras; the virtual world is full of images. Where does all this photographic activity leave the artist-photographer? Post-Photography tries to answer that question by investigating the exciting new language of photographic image-making that is emerging in the digital age of anything-is-possible and everything-has-been-done-before. Found imagery has become increasingly important in post-photographic practice, with the internet serving as a laboratory for a major kind of image-making experimentation. But artists also continue to create entirely original works using avant-garde techniques drawn from both the digital and analogue eras. This book is split into six sections – Something Borrowed, Something New, Layers of Reality, Eye-Spy, Material Visions, Post-Photojournalism and All the World Is Staged – which cover the key strategies adopted by 53 of the most exciting and innovative artist-photographers of the 21st century, drawn from all over the world.
