In his series 'Time is a Dimension,' photographer Fong Qi Wei stretches the boundaries of still photography to produce images that convey the passage of time. Rather than using simple time-lapse, he has created a series of photo collages, each composed of many 'slices' taken in a 2 to 4 hour timespan. The resulting images capture the changing colors of sunrise and sunset in a way a single conventional still frame, or a video can't match.
