This work aims to explore the relationship between the photographed subject matter and the pinhole camera. The moon may be dim or bright, wax and wane, the lunar phase is the shape of the directly sunlit portion of the moon as viewed from earth. A stone is placed in the center to signify the moon; the flashlight facing the stone symbolizes the sun; the film tubes 1 to 7 are organised in sequence around the stone, which represents the position of the earth viewing the different parts of the moon. I transform the toilet at home to a darkroom, I cut out circle photo paper and put it into the film tubes and turn on the flashlight for development.
