As its brattish title suggests, I Want It All is an exhibition that aims to cater for London’s most demanding punters. And if big names are what you’re after – on both sides of the lens - then it certainly delivers. Pop idols, movie stars, celebrity chefs and even Her Majesty the Queen feature in this collection of images, as does a host of famed photographers past and present, including the late Bob Carlos Clarke, Sixties veteran Terry O’Neill and modern artist Chris Levine.
