If you look at the last [photo in the article, you'll see that the original picture shown in the beginning of the article was cropped by the frame and matting. This cropped out many of the horses running that were included in the original picture, a different photo. I saw this in a Richard Avedon show on New York's Long Island Museum. It seemed to me that the cropping excluded stuff. I couldn't believe Avedon would chop off things I saw chopped off. When I asked the museum's guide, she said, no, nothing was cut off. I forget who she said framed the picture. In any case, I don't believe her. The cropping just wasn't right.
I just wonder, how many photos of famous pictures we see that just aren't shown the way the photographer took them never mind that a different photographer took them than reported.
