Photojournalist Kevin Lim loves sports, but assisting three Straits Times (ST) reporters during the 2016 Olympics stretched him to his limits.

Competing with hundreds of other photographers at each sporting event only added to his stress.

But, Mr Lim, 34, sees it as the highlight of his career so far.

The ST photojournalist shared what it was like to shoot the Rio Olympics at a talk yesterday.

He was speaking to an audience of about 40 people at the National Museum of Singapore about his favourite photographs and the challenges of shooting the most prestigious sporting event in the world.

Doing it in Rio de Janeiro, Brazil, brought its own specific difficulties, such as safety - one of the buses ferrying journalists was attacked.

He also said that it was a privilege to capture Joseph Schooling's historic gold medal win in the men's 100m butterfly.

Speaking about the entire experience, Mr Lim said: "It still feels like a dream."

The talk was the last of a series held in conjunction with the 2016 World Press Photo exhibition presented by The Straits Times.

Ms Sonali Manimaran, 21, an earth science student at Nanyang Technological University, loved the exhibition. "It gave me goosebumps. You read about things in the papers, but it never really impacts you as much as seeing it for yourself," she said.

The free exhibition closes at 7pm today. The last guided tour takes place at 12.30pm, and is limited to 20 people, with places given on a first-come-first-served basis.
