Photo collages record passage of time in 'slices'

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 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 still or video clip can't match. Click through and take a look at some of his work.
