You know it when you leaf through his collection of photos, The Here and Now (HarperCollins): Sam Jones is a man of mischief. That's why George Clooney, in his pool, also waddles around in flippers for this celebrity photographer and director, why Renèe Zellweger giggles like a ticklish kid. Jones is an artist who covers a street with banana peels, then lets loose his subject, Steve Martin, to make a scene. For a photographer this inventive and engaging, even world-class celebrities get real. That's candid camera at its best.
