Thomas Struth's &
The photo is not staged.
Struth waited, as I've said, and then waited some more to get the picture. He would say, "make the picture."
He took it at that precise moment that the museum-goers positioned themselves before the painting, taking their cue from the arrangement of the figures in the space of the painting as if instructed by the painting on how and where to stand.
Or look at this:
A photo Struth took at the Chicago Art Institute. The painting is also quite well-known, a painting by Caillebotte, called "Paris: A Rainy Day" painted in 1877 and even may itself have been painted with the aid of a photograph.
Again, first the painting by itself and then the Struth photo with the viewers included in the view.
Look at how the two viewers have arranged themselves.
Not merely a view of a street in Paris in 1877, "Paris: A Rainy Day" is - at the same time - a set on instructions, instructions to museum-goers on how and where to stand before the painting in the gallery.
