“Neighbours” is a light artwork by Tochka presented at Amsterdam Light Festival 2018 in Amsterdam, Netherlands.
Painting with light - it sounds magical but impossible. But people have been doing it for a long time – since 1889! It’s not difficult to do, you move a lamp through a dark space and capture these movements in a photograph using a camera with a slow shutter speed.
