Two decades of creative accomplishment have made Kersalé's studio a top address for innovative lighting design. Richly illustrated and extensively documented, this publication provides the first-ever comprehensive overview of his work, both permanent and temporary installations, in which this artist of the night de-familiarises our way of regarding objects, paints them in a different light and lends them new character.
