Faced with the proliferation, indeed the overflowing, of photography, with the omnipresence of the image and the pressing of messages, stimulus, persuasion, at times even prevarication, phenomena that all demand our attention with the utmost urgency, there is no shortage of those who have stopped to reflect on the problems this raises, on the shocks and habits that derive from this constant exposure. Sontag has done so equipped with the most varied keys, technical and sociological, aesthetic and even moral: the essays she devoted to this theme occupy a special place, because all the motifs, suggestions, problems and relationships are not only rethought and proposed again with a very attentive and perceptive eye, but also tested by continually widening, and in a happily unprejudiced way, the discourse to the entire cultural and political situation, identifying a network of meanings in the evolution of photography that shed new and different light on the phenomenon.
