    Constantine drone footage and photography (CAV Aerial) delivers fresh perspectives and brings to life the exciting and invaluable mosaic of London's green spaces.

    Seen from above you get a fresh take on the shapes, textures and colours which fill our urban landscape and deliver so much value to our lives. His photography then adds ground level detail while capturing the play of light through leaves, stems and branches.

    London Parks and Gardens treasures Constantine's input and critical eye ... we happily endorse Constantine.
