In an ongoing series entitled Sky Art, artist Thomas Lamadieu aka Roots Art, takes photos of buildings and cityscapes wherever he travels. Many of his images point skyward using a fisheye lens. He then uses the sky in each photo as his canvas, filling it with illustrations that incorporate the sky’s natural colour.

To see the entire series, check out Lamadieu’s website and be sure to follow him on Facebook and Twitter for the latest updates.
