In an age of digital retouching and the relentless pursuit of the perfect image, Nan Goldin stands apart for her love of imperfection. Reality looms large in the Boston artist's pictures, where blurry shots and intense colours capture a fleeting moment in time better than any photoshopped image ever could. In this exhibition, her biggest yet in Brazil, photographs and slideshows capture her work from the 1970s to the present day. Goldin herself says: 'My work comes from the snapshot. It is the form of photography most defined by love. People shoot pictures out of love, and to remember - people, places and moments. They create a story reporting a story.' Her hugely influential work has already been seen all over the world, especially the pictures she took documenting an underground scene in New York featuring transvestites and other characters on the peripheries of society.
