Time and Space are the unchanged theme that Chang Chao-tang has lived up to for years. In the main melody of black and white, the nature of time is the meaning of human being instead of the object's movement. Looking for non-reality in reality is a fuzzy space that stands in between visibility and invisibility. A series of work of projections implies a subject's ça-à-été (it has been) as well as an object that is absent. It presents two spaces, i.e. a direct scene and an extended one. Chang Chaotang grew up in an era of a changing society. He turned from a "flâneur" to an image documentary and film editor, which included the operational thoughts of both cinema and photography. His unleashed inside and scream formed a headless figure. It was body vs. non-body; a view of somebody's back stared at the existence of suffocation. At the age of 19, Chang Chao-tang abandoned the Salon photography or Documentary photography and took his first picture that up to date is still an inevitably fantastic image. We fell into bottomless abysses of time and dark night of soul with his black and white images. He challenged the metropolitan's long standing silence with his images. His work has been floating around city and suborns implementing a kind of wander and meditation, and yet observing the city with a bird's eye view. The spiritual power of ruins has been seen and is looking for the dilemma between sanitization and secularization. A ready-to-go crowd of people was held up along with the photographer's self-projection. A journey to collectively fight against destiny is just about to begin.
