Excellent example elevenaugust! I often see poles which are off vertical, especially in the case as illustrated, where the pole supports wires which are going off the direction of the main lines and are pulled from being vertical in the direction of those other wires. In the Rajmann1977 photo16, two notes: one, the wires on the top crossbars change angle, and, two, the pole already has a supporting cable attatched to the left side of the pole to help offset this pulling effect. It is common in that case to have the pole off vertical, and in photo16 this should be to the right side, bisecting the angle formed by the wires on the top of the crossbars. This will exagerate the shadows on the pole and make the image look somewhat "earlier" than it actually is. My impressions are that the sun angle is about 10 degrees and this is about an hour from sunset.
