Flickr photographer 45mr takes light painting to a whole new level with these gorgeous long exposures taken on the waters surrounding Tokyo, Japan. As the main watercourse that flows through the metropolis, Sumida River is breathtaking enough but, add in these light trails, and now you have something fantastically futuristic.
For the image above, the photographer used an exposure of 100 seconds to capture the light trails of house boats and other water transportation as they made their way down the river. In each case, post processing was done using Adobe Lightroom 4.
