Berndnaut Smilde was born in 1978 in the Netherlands, and now lives and creates art in Amsterdam. As an artist, he is interested in impermanent states of being, a theme that resurfaces in much of his work. While Smilde’s indoor clouds look as fluffy and white as those you see perennially dusting the sky, in reality, they last just mere seconds. Few people have had the pleasure of seeing Smilde create the indoor clouds, though many individuals have borne witness to his stunning photos.

Berndnaut Smilde’s formed his first indoor cloud—displayed as an installation named “Nimbus”—in a bright blue room that evoked summer skies. Smilde’s desire to use clouds as an art medium, particularly indoor clouds, comes from his interest in how they can temporarily change a space. To create the indoor clouds, Smilde must maintain a specific temperature that’s warm enough to condense dust particles, yet cold enough to keep water vapor from fully condensing into rain. Smilde also maintains a specific moisture level.

While Smilde has received generous praise worldwide for his incredible indoor clouds, he’s also created numerous installations, sculptures and photographs that have nothing to do with cloud formations. Smilde has exhibited his various artwork over most of Europe.
