To understand how profoundly cameraphones, digital cameras, and photoblogs are changing the way society disseminates information, one need only recall the horrific Abu Ghraib Prison images that filtered out of Iraq. With cameraphones now outselling digital cameras, amateur photographers are becoming volunteer journalists, capturing images both mundane and profound and publishing them everywhere. After providing a brief overview of cameraphones and photoblogging (including moblogging and camera-to-camera imaging), journalist and author Chris Colin examines the many ways people are using their cameraphones: in photojournalism and art photography, to document and influence public opinion, to publish visual diaries, and to illuminate little-known societies and locales. Finally he provides a guide to photoblogging for readers who want to not only to witness this new phenomenon, but to participate in it.
