What is light? When you wake up every morning, open your curtains, and see that the day’s light has come again, it’s no big deal. For nature, however, it’s an important clue in controlling biological and physiological changes in life forms. Light controls plants’ growth and flowering hormones; it’s also linked to people’s emotions, often causing irritability for no apparent reason. Other times it’s about the oversaturation of light and the dissonant, artificial light ubiquitous in modern life. Shot from a photographer’s point of view, the film intuitively seeks good light while also examining light’s existence from agricultural and cosmic perspectives.
