The thing is, she's the model. She's standing above them because she needs to be in prominence in the picture...because she's the model. You can make an argument that maybe two of the dudes are looking up at her but the majority of them are looking at each other. I get where you're going with the latent white messiah complex that does get pushed in mainstream media at times, but if that was an America's Next Top Model shoot the model would be on that rock regardless of her race. If there wasn't a rock she might stand in the middle but slightly in front because the whole point is to highlight the model. But like I said, we, rightfully so, are drawing from our dispositions which have been influenced from a history of racial injustice when we look at these pics. The thing is sometimes we look way too hard to try to be offended.
This pic is from the same Vogue shoot:
It's clearly not going for the high end fashion style of the first pic. When we look at that first pic and the first thought is about who is establishing superiority it becomes a troubling statement. And the even funnier thing is that this isn't a model in either picture it's Keira Knightley from the Pirates of the Caribbean films. She went on an African safari and took some photos . So it wasn't some modeling agency deciding to go to Africa cause it's cool to use Africans in pictures. She was on vacation and Vogue decided to take some pics. But we shouldn't need to know any of that to stop us from rushing straight to assumptions of latent racial superiority being pushed. If cats wanted to have a serious discussion of the limited perspective and scope of Africa we tend to get from Vogue, publications of that ilk, and popular media in general, that would be a far more enlightening convo.
