TateShots offers a behind-the-scenes look at Peter Doig’s 2008 London show of more than 50 paintings made since his 2002 move to Trinidad and the time of the Tate Britain survey. Doig walks us through the exhibition and opens a suitcase to share some of his source materials, which expose how the canvases evolve from photographs to prints to paintings. Discussing Man Dressed as Bat, the most current painting in the show, the artist reveals how rain coming into his studio helped create the marks on the canvas and experimentally shaped the final, ephemeral outcome.
