The photograph is literally an emanation of the referent. From a real body, which was there, proceed radiations which ultimately touch me, who am here; the duration of the transmission is insignificant; the photograph of the missing being, as Sontag says, will touch me like the delayed rays of a star.
Roland BarthesI want a History of Looking. For the Photograph is the advent of myself as other: a cunning dissociation of consciousness from identity. Even odder: it was before Photography that men had the most to say about the vision of the double. Heautoscopy was compared with an hallucinosis; for centuries this was a great mythic theme.
Roland BarthesThe Photograph belongs to that class of laminated objects whose two leaves cannot be separated without destroying them both: the windowpane and the landscape, and why not: Good and Evil, desire and its object: dualities we can conceive but not perceive... Whatever it grants to vision and whatever its manner, a photograph is always invisible: it is not it that we see.
