In Pictures: Stories from the 1960s and 70s, told through the lens of cleaner Lui Hock Seng

Mr Lui, 79, who works as a cleaner at Singapore Press Holdings (SPH), became interested in photography as a teenager in the late 1950s. The third of six children, he could not afford a camera until his eldest brother bought him a German-made Rolleiflex about 55 years ago. The top-of-the-range mechanical camera, which used photographic film unlike digital cameras today, cost $300 - a large sum in those days. These are his best shots taken with the camera.
