Point taken, Hamish. I don't normally take pictures of art. But I like pictures of people looking at art. In the series above I wanted to give context to the images and I thought the first picture might be a way to emulate through the photograph a reaction similar to what one might experience on the scene; a little bit of surprise and maybe even a modicum of shock. The second image was to show the piece in situ, and the remaining shots I intended to show the reactions of passers-by.
Thanks for your comments, Hamish.
