Winter Wonderland is held each year in London from late November until early January when a village of attractions, food stalls and a Christmas market appear in Hyde Park. It get enormously crowded but can be great fun too even just to wander around and see the sights.
On this occasion I was experimenting with longer exposures to transform the rides into streams of colour. Getting a good balance of movement without heading into chaos needed a careful choice of shutter speed. Too long and things became too abstract for my liking. Too short and the sense of movement wasn't expressed adequately.
Of course a tripod was essential to keep the camera still during the long exposures. Standing still while the exposures were made on very cold nights in London tested the warmth of my clothing and in particular my socks which held up for a while before that solid cold of standing around on the freezing ground soaked the heat away.
