I have photographed Masjid Wilayah Persekutuan under different light since its opening in year 2000. Fascinated by the intricate architecture and how sunlight interacts with the interior arches and stairs, I always enjoy walking around the huge mosque to look at the shadow play.

It was only recently, that I was able to quickly calculate the exact position and declination of the sun with a mobile Android app from location. At one of my favourite angles, the app projected a perfect sweet spot but only in six month’s time. The sun’s relative angle in the sky changes over seasons.

I waited and that moment arrived two days ago. However, there remains one unpredictable variable; the weather. Resulting picture in the next post.
