[...] the photograph is not in its
essence a transparency through which we gain access to a known reality
but, on the contrary, a source of ambiguity and perplexity. The
photographic image is a constellation of questions for the eye because
it offers viewers forms and signs they have never perceived as such and
which conflict with their natural vision. [...] For the eye, every
photograph is an enigma. The human gaze directed at the photograph
reveals an enigma, which in turn echoes the eye's own questions.
Michel Frizot, Toute photographie fait énigme
