"Sontag reappraises many of the opinions she laid out in her well known 1977 book On Photography. That earlier volume gave us a searing indictment of photography, arguing that it limits 'experience to a search for the photogenic, by converting experience into an image, a souvenir' . . . [Regarding the Pain of Others] focuses on how we look at photographs of calamities and the moral implications of such observation . . . A nuanced [and] revisionist coda of sorts to On Photography . . . Sontag is to be commended for acknowledging how her thinking has changed over the years."—Michiko Kakutani, The New York Times
