Three years, a lot of photos and 10 terabytes of data.
That's all it takes to create an almost five-minute spectacular timelapse video of Singapore's growing urban landscapes.
The Lion City II - Majulah was created by Singapore-based Australian photographer Keith Loutit, which he says tested his patience.
"When we pass by landscapes they appear fixed in time, but they change around us constantly. The idea behind this film is to reveal this change by returning to the same camera positions over the years," he writes in the description accompanying the video.
The music was created by Michael Miltersen in collaboration with Mr Loutit.
"Special thanks to Michael for the composing the amazing soundtrack, and for keeping me motivated over the past few years of shooting," Mr Loutit says.
Mr Loutit was one of the pioneers of the technique known as the tilt-shift/timelapse technique which brings time and focus together to make ordinary things look miniature.
