Week 2 of The Straits Times Samsung Galaxy S9 After Dark Photo Challenge has ended.

Changi Airport is not an easy place to photograph with the ongoing construction work. But we were awed by some of the creative entries and the effort put into composing those shots. A really big thank you to all who have submitted their entries.

But there can only be one winner. And for the Changi Airport challenge, the winner is Betty Thu.

The winning entry shows a rather unique perspective of the Changi Airport. We like the way the triangular panels have been used to frame Changi's iconic control tower. The tower's reflection on one of the panels add the wow factor. Great composition as well.

Again, don't be discouraged if you fail to win this week. There are still seven Samsung Galaxy S9+ (64GB) worth $1,348 to be won over the next seven weeks.

Plus, each week's challenge is unique. As such, you can win more than one Samsung Galaxy S9+. So don't give up and continue to send those entries our way.

For this week's challenge, the location is Sentosa. It can be anything in Sentosa, from Universal Studios Singapore to Siloso Beach. Wow us with what you got.

There is no restriction on the brand of the smartphone used, except the photo must be taken on a smartphone camera. Please ensure the photo's IPTC data can be read.

Submit your entry via email to stdl@sph.com.sg with the header "ST Samsung S9 After Dark Photo Challenge: Sentosa", along with your name and mobile number. Please use the same email that you use to log in to The Straits Times when submitting the photo entry.

Deadline of submission for this week's challenge is 2359hr, 6 May 2018.

We will pick the best photo of the week and announce the winner on The Straits Times Tech website (www.straitstimes.com/tech) on 9 May 2018.

At the same time, we will also release the new location of the next challenge.
