Artist and photographer William K's Body Connexion – Berna and Bertan is a series of images expressing a brother and sister's link in their dance. The siblings are Circus artists and dancers based in Berlin, and are shown mirroring, supporting, and complementing each other in their physical poses. The comfort seen in their actions, along with the natural visual harmony that is created, results in clean and serene shots of dynamic motion.
