Sargy Mann: How a blind painter paints
In the last weeks of his life, the artist Sargy Mann began writing about his extraordinary career as a blind painter. The last 10 years of his life, after his eyesight had failed completely, were paradoxically his most successful - his final exhibition opened in London this week, two months after his death. Here he reflects on the nature of perception and the visual experiences that continue after the loss of sight.
