Present tense

"The National Portrait Gallery exhibition Present Tense: An imagined grammar of portraiture in the digital age considers the alliance between portraiture and technology and investigates how different ways of imaging reflect how the individual is perceived as well as how the various mechanisms of imaging that are used to manipulate that perception. Present Tense includes examples of the informal and immediate digital snapshots made with mobile phones; images recorded with sonograms that reveal faces that cannot be seen by the unaided eye; 2D and 3D portraits generated exclusively from binary code; and the more expected videos and manipulated photographs. A number of artists in the exhibition ignore the rising tide of digital imaging processes to favour old technology and create powerful images with the archaic daguerreotype technique or cruder still, old-fashioned stencil."--Publisher website.
