Voices and images at Venice's Palazzo Grassi exhibition

VENICE: Venetian canals transformed through a camera oscura, intimate snapshots of a prisoner's life and a hall of whispers are among the installations on show at a new exhibition at Venice's Palazzo Grassi.

Around 30 works by 27 international artists, borrowed from French billionaire Francois Pinault's private collection, explore how the medium of video has been used to capture and challenge sensory expression and perception.
