Google has launched a worldwide photography competition for student photographers. The 'Google Photography Prize' will be hosted on Google+ - the search giant's social networking service. Prizes will be awarded by a jury of photography professionals, including curators at London's Saatchi gallery. Over 100 Samsung Galaxy Nexus phones will be given away as prizes during the competition, and 10 finalists will have their work showcased at the Saatchi Gallery in London for two months. In addition, the grand prize winner will be sent on a once-in-a-lifetime photographic trip to a destination of their choice, in the company of a 'professional photography coach'.

According to Google, more than 3.5 billion photographs were uploaded to Google+ in the first 100 days of its existence. To put this in context, Facebook reports that its users upload more than 250 million photographs per day – 25 billion every 100 days. Unsurprisingly, by entering the competition, entrants to The Google Photography Prize grant Google and its affiliates the right to use their images for the purposes of promotion and advertising for both The Google Photography Prize and the Google+ service.
