The astonishing Blue Mosque and the Haghia Sophia are about two football fields apart with a lively square, Sultanahmet, between them. Not really an actual square but a rectangle. Because of our hotel's proximity to the mosques, I was able to spend more time there than other mosques around the city. One memory I will always have is trying to look straight up to photograph the spectacular ceilings and keep them as symmetrical as possible. The mosques are quite dark with small lights or light coming in from the stained glass serving as the primary source of illumination. They are also places of worship, so the visiting hours, while regular, are broken by times of prayer. It was very enjoyable to take the long exposure photographs like in the second picture. I had a tripod, of course, and had to stand close behind it to keep people from knocking into it. The other issue was people gathering right in front of the lens and talking for ten seconds or more, ruining the picture. I'm not complaining mind you. I was lucky to just get to see these places. Sony cameras, the NEX 7, NEX 5n, and RX 100.
