Time-lapses? They're awesome photos like this, except slightly more like those new-fangles 'moving pictures' we keep hearing about.

If you're a fan of London and of shooting time-lapse videos, don't miss this: Our good friend Nicholas Goodden (one of the top 100 most socially influential photographers in the world) is taking the helm on an awesome project: A one-day event where we are creating a love story to London, through the medium of time-lapse.

Sure, there's no shortage of time -lapse videos, but how many of those have you been part of? Well, here's your chance. Mark the 6 December in your calendar, and get yourself signed up.

'We've got a dozen photographers already signed up,' says Triggertrap's Head of Happiness Helena Vieira, 'and we'd love to get some more of you involved.'

Well, you heard the woman - sign up here!
