The annual Sony World Photography Awards began in 2007. They showcase the work of both professional and amateur photographers across genres which inclu de journalism, fashion, architecture, advertising, sport and music. This year there were over 60,000 images submitted from 139 countries. Each year, the winners and runners-up are collected in an exhibition which tours the world. The London stop of the tour opens today at the Art Work Space gallery in London W2. Here is a selection of images, with short commentaries by the photographers themselves.
