Started in Paris, the series Voyages sur le Motif is mostly the result of several stays in Brittany. Each canvas was painted in front of nature, facing the sky, and bears the name of its place of creation: Champ de Mars, Dinard, Baie du Mont-Saint-Michel, Île-de- Bréhat, Crozon, Île Bruc, Belle-Île… Renk follows the path of the impressionists and, as they did, carries his equipment to paint outdoors, without prior sketch. He paints “sur le motif”, “on the spot”.

Self-taught artist, he uses spray paint to represent skies in which the colors fade to reveal the harmony. The sky is at the center of his search, not for its picturesque effect but to illustrate, with spontaneity, the variations of colors, shadows and lights. These works are an accumulation of his tag “Renk”, in different sizes and colors, endlessly repeated until it disappears.
