"it is a mistake to associate photography, by reason of its technical origins, with the notion of a dark passage
              (camera obscura). It is camera lucida we should say...for, from the eye's viewpoint,'the essence of the image
              is to be altogether outside, without intimacy, and yet more inaccessible and mysterious than the thought of
              the inner-most being; without signification, yet summoning up the depth of any possible meaning; unrevealed
              yet manifest, having that absence-as-presence which constitutes the lure and fascination of the Sirens'"
                      Roland Barthes, Camera Lucida
