Compared with some of her other work, this seems quite conventional and 'safe'. Sometimes with Arbus I feel like I'm in a freak show and that by looking at her subjects I am in some way contributing to their exploitation, and it is hard to separate this image from those other photos and the way they make me feel. I'm sure that is the whole point, the reason why her work is important, because it challenges you to consider whether her subject matter is right and proper, or whether it is exploitative.
Taken on its own I can see how people think they're being kidded by Identical Twins - it's the Emperor's new clothes, isn't it? I don't yet feel confident enough of my own critical abilities, 'taste', call it what you will, to be sure that I wouldn't think the same if I hadn't seen other Arbus pictures, and this isn't as obviously an important image as some of them, but I feel a tension there because as I said the dwarves and the Down's people and all the rest seem to be part of the reason why her work is so much more than snapshots. There is plenty more in this image, about individuality and perception of sameness, a slightly creepy sense of the American Gothic about their eye contact, straight on to the camera. Thanks for raising this bapp.
