German photographer Jakob Wagner added a bit of sci-fi flair to nightscape photographs of the world's largest cities in his art series Urban Zoom.
Wagner explained how he did it in this interview over at DIY Photography:
My photograph "Urban Zoom #1" is part of an personal long time photography project, which I worked on since 2005 until now.
I’ve shot the first photo of my 'Urban Zoom' series in London 2005.
I tried using long exposure times, camera movement and zooming during the exposure to capture the slow-flowing and constant change of the city, in an abstract way.
The result has pleased me so much that I decided to create a series of abstract images with as many abstract photographs from big cities around the world as possible.
Meanwhile I have captured more than 20 "Urban Zoom" photographs.
