It may not look cold but this warehouse in Rainham was -26ºC, making it the coldest place I've every shot. A full 6º colder than at 5000m in the Himalayas. At first it's bearable but the cold slowly creeps in and within minutes my hands were useless stumps. The batteries of lights, camera, triggers etc drained in minutes and cables became frozen stiff. Quite a strange experience and we were relieved to get out into the balmy November air. It took us hours to warm back up again, unlike Chris here who's clearly made of sterner stuff.
