In his talk ‘Heterochronia*: Projections of Temporality’ Thomas Y. Levin pointed out some interesting issues occuring through the increasing hybridity of the image provoked by the synthetical processes of the digital. A short simplification could put it the way that through the shift of the photochemical to digital the traditionaly assumed indexicality of the shot image moves and inherents now the logic of the temporal – leading to new rhetorics of ‘live’ (transmissions).
Thus it is just consequent that as much as the ‘surveillanvce image’ has to be considered as the ‘real‘ real-time image the semiotic anxiety of the contemporary temporal condition of the hybridity of images increases. Semiotic heterogenity turns the index into a pure figure: indexicality becomes a rhetorical iconic figure of semiotics. In short – indexicality changes its rhetorics towards the temporal – or in the words of Levin:
*Heterochronia (in med. terms) means the origin or development of organs or tissues at an unusual time or out of the normal sequence. Heterochronia comes from the Greek word “heteros” meaning “other,” and the Greek word “chronous” meaning “time.” Put the words together and you get “other time.”
