SINGAPORE - Slowly but steadily, they practise under the watchful eye of coach Mohd Faizal Mohammed, 31.
Every Wednesday, it is a splashing good time at Hougang Swimming Complex for 20 children and youth from Chen Su Lan Methodist Children's Home and The Salvation Army's Gracehaven. It is part of SportCares' Swimming Programme, a free course to help them build water confidence.
This photograph was shot with a Samsung Galaxy S9. Its dual aperture automatically adjusts to any lighting conditions, be it day or night.
Using the pro mode, Straits Times photojournalist Mark Cheong switched between apertures of f1.5 and f2.4, with an ISO ranging from 400 to 800, and toggled with shutter speeds of between 1/10 and 1/250 of a second to capture images of the swimmers under the glow of the pool's floodlights.
