There's something odd going on; draw a line from the tip of Kerry's nose to the tip of his nose's shadow. Do the same for the guy next to him, in the white tee-shirt. They are parallel, as one would expect. Now draw a line from the elbow of the guy in the teeshirt to the shadow of his elbow. I submit that by inspection one can see this line is not parallel with the first two (nose shadow) lines.
Now, draw a line between the left bottom corner of the black guy's shirt, and the corresponding shadow of it projected onto the leg on the sailor to the right (from the camera's perspective). This doesn't line up with any of the previous shadow lines, but IS parallel with with the shadow of the nose on the sailor to the right of the black guy.
Now, unless I'm forgetting something about projective geometry, it would appear that the two rightmost figures in the picture were photographed under slightly different lighting conditions than is seen in the rest of the picture.
Also, the shadow of the arm of the tee-shirt guy seems too sharp, as though someone created it with a digital photo editor. It seems to lacks the blurring you expect from a solar induced shadow projected over that distance (because the sun isn't a point source of light.)
Look again at the shroud - half is cloth, then the middle is (blurred, then the left is "water".
Look at the clutter on the bottom of the boat, but is missing (somehow) in the photo of the leg of the "reverend" traousers, and the "missing pants" leg of the guy in the middle - who ISN'T leaning on the "missing" left side of the "missing" shroud.
