The ‘queens’ in these perspective shots are the Cunard liners Queen Mary 2 and Queen Elizabeth. I’m going with the geometric definition of Perspective: the way that objects appear smaller when they are farther away and the way parallel lines appear to meet each other at a point in the distance.
Below, not only do the farther deck chairs look smaller than those nearest the camera, but various parallel elements (the deck caulking at left; the top and bottom rails at right) appear meet each other at a point in the distance.
More amazing meeting parallel lines, this time in corridors.
July is Squares Month, and the theme is Perspective.
