Story of the Photo:
It's not easy to capture Hagia Sophia without any guests in the picture. To achieve this, i waited until everybody quits. At that moment, I was the last one inside. I liked the reflections on the ground, so I wanted to keep reflections in the picture as much as possible. It was not allowed to use tripod and light was low. So, I increased the ISO to 800 and use f/2.8 aperture. Canon EF-S 17-55 f/2.8 IS lens was used. This lens was able to produce pretty sharp images even at f/2.8 and IS prevented occurence of blur.
