I (Chris) was back on Photo24 London for my fourth consecutive year. It's a 24 hour photo shoot, some set competition themes and 200+ photographers taking part. This year I went along with good friend and fellow blipper MartinN. Starting just after midday we took in Southbank, Canary Wharf, The O2, Emirates Airway before heading back to Westminster for a specially arranged "flight" on the London Eye just before sunset. We then headed back to the city for a nightwalk but having looked at the number of photographers joining it, we decided to make our own route. That took us to midnight so I'll finish the tale on tomorrow's blip.
