However the shadow of "Oswald" do not get shorter as they should. In fact, they get longer.

Anybody know what causes this phenomenon?

p.s. the three photos were allegedly taken within minutes of each other, but the shadow of the cables move about 6" down the post which would take at least half an hour.

What gives?

Let me take this one, if no one else will.

• The sun was going down, so the sequence is C-B-A.

• How do we reliably compare the length of the shadows? They fall on a 3D surface, and Oswald was moving around.

• The speed with which the cable shadows move up the post depends on the distance to the cables. Is that distance known? Is it important to know how many minutes the event lasted?
