We like to tell ourselves that we know a good shot of urban life when we see one. The way the light might bounce off a tower block, or the juxtaposition created between a tramp and a Bentley. Then we saw the winners of this year's CBRE Urban Photographer of the Year award, and realised we didn't even have skills of a 15-year-old.
The brief of the award attempts to capture the 24 hour lifestyle of the world's urban centres - photographs must depict an aspect of city living, with entrants listing the hour in which their photo was taken. Twenty four winners are then selected, one for each hour of the day, with further awards bestowed upon the best shots from two age brackets - 13-15, 16-25 - and three geographical regions: the Americas, Asia Pacific and Europe, Africa and the Middle East.
The title of overall winner went to Marius Vieth for his shot 'Mask of Society'.
