I took this photograph with long exposure: I aimed the camera at the new moon, and then rotated the camera in a full circle within 1.3 seconds. The light from the new moon was traced as an orbit in the film. After about a hundred attempts, the new moon finally became a full moon.
A square is defined as having all sides equal in length, and its interior angles are all at 90 degrees, though its shape does change according to one's position. So, in reality, our eyes have never actually "seen" a real square, as it can only appear in our imagination.
I drew a horizontal line on a map of Victoria Harbour, and the line went through a total of five intersections on the coastline. I filled up plastic bottles with seawater from those intersection points, each the same amount, and then I put the five bottles of seawater at home - A continuous sea level emerged.
I stood in front of a 13-storey building in Sham Shui Po and waited for all the residents to fall asleep. The photographs were taken at 22:38／01:40／02:36／04:09／05:04. A person in the building remained awake throughout the night, we ended up wasting a night together while being on opposite sides of the street.
