Catalan photographer Xavi Bou was always fascinated by birds - and figured out a unique way to photograph their flight patterns. "One day I asked myself what kind of trail the birds would leave in the sky if that were possible," he told My Modern Met. "It was then that I imagined the lines they would create and so I began to investigate how to make them visible." The resulting series, which he calls "Ornitographies," is a combination of photography and motion study, capturing the shapes generated by migratory flight patterns, and creating something uniquely beautiful in the process.
