In Lyon, France, 7-8-9 december 2012.
It's a true wonder, streets and buildings are living parts of a great lightshow / soundshow dedicated to architecture, history, arts, fantasy, comics, all of that resolutely turned towards the future.
The Festival of Lights exists since 1852 ; 3 or 4 million people came in 2012 ...Sorry for the poor quality of my images (I didn't have a tripod, no room to put it on the crowded street !), they are high-iso and DxO did a great job to soften the noise !
Enjoy, and if you can, go there next year !
