An environmental portrait

I'm in Egypt now beginning a photo tour here, and in the old town of Cairo today we visited a bazaar and this 800 year old mosque. In many Muslim countries in the Middle East, many people, especially women, are reluctant to be photographed. I asked this young lady if she would pose for my group and she was happy to do it. The large majority of women here are dressed in modern clothes without covering their heads, but I seek out models that are exotic and mysterious to a Westerner because I'm always trying to show the uniqueness of other cultures. That's why I singled out this particular young woman. The semi-circular niche in the wall, highly decorated, is the Mihrab. This indicates the direction toward Mecca, and hence the direction Muslims face when praying. I used my new 14mm Sigma f/1.8 wide angle lens, and I partially corrected the keystoning in Photoshop (using Select > all, and then Edit > transforms > distort). I straightened the columns on the right to be parallel with the frame but left the left hand side angled inward. Using a wide angle lens for an environmental portrait results in a unique look. The subject is disproportionately large compared to the background. This is natural light, and my settings were 1/100, f/8, 1600 ISO. Because all of the illumination came from diffused daylight, I used daylight white balance.
