That must be some photo
Not necessarily __ it just happened to be the image that most closely fitted the buyer's needs. The price is determined by how the image is to be used, not for it's artistic merit.
A very ordinary image of a straight road through scrubland sold for a similar amount when it was used as the backdrop for a movie poster. You couldn't actually see much of the original image because the movie stars were superimposed over most of it.
