When I was in Egypt I wanted to take a photograph of a Bedouin woman in the valley beneath Sinai, what a great picture that would be.
I would imagine though, that Sarai had to know that taking pictures of women could be seen as disrespectful if they were wearing a hijab. But maybe she didn't really understand that men would take it the same way.
It may have been that she was taking pictures of scenery that didn't make sense to the guy, ex, she liked odd subjects, so perhaps he simply assumed she was taking pictures of them.
She didn't seem to use people as subjects, here in NYC it would not go over very well at all.
At the same time, recently there was a great deal of attention given to the film "The Wasteland" The subject of the film was garbage pickers.
Perhaps this may have influenced her and caused her to try to take pictures of the men. I'd like to see if she mentioned it anywhere on Instagram.
