Photograph shares being with its subject
A photograph is not a likeness someone made but an imprint mechanically taken from the object by light, like a fingerprint or a death mask. Because no human hand intervenes in its formation, the viewer grants the image a credibility no painting can earn: we accept it as a transfer of the thing's reality, not a representation of it. Bazin roots this in a 'mummy complex', the old human urge to preserve bodies against time, which photography finally satisfies by embalming the moment.
