LONDON.- This autumn, to coincide with the Sainsbury Wing exhibition Venice: Canaletto and his Rivals, the National Gallery has invited contemporary artist Ben Johnson to display his work in an exhibition in Room 1. Ben Johnson paints the city, for very different reasons, and with very different outcomes. The display reveals his motivations and working processes and his fascination with the legacy of Canaletto. In this display, Ben Johnson will be completing one of his paintings in public. Following the example of Canaletto, Ben Johnson combines and manipulates different views to make paintings that are completely convincing. Along with large-scale cityscapes including depictions of London landmarks Piccadilly Circus and Trafalgar Square, preparatory drawings and photographs are shown that demonstrate how this artist produces such apparently realistic paintings with differing techniques and tools.
