Xavi Bou focuses on birds, his great passion, in order to capture in a single time frame, the shapes they generate when flying, making visible the invisible.

Unlike other motion analyses which preceded it, Ornitographies moves away from the scientific approach of chronophotography used by photographers like Eadweard Muybridge and Etienne-Jules Marey.

In Ornitographies, the skill envied by men, the long-lasting shared yearning of flying, is presented to us, extending our visual perception.Art and science walk hand in hand to create images, which are no longer a single portrait of reality but become a witness of the instants that, for a moment, were past, present, and future all at once.
