[QUOTE="Teri Anne, post: 2296448, member: 118816"] Good Evening, Both of these videos show that there is a relationship due to movement of the Sun. That is no news. Ever heard about a Sun Dial? Been around since around 3500 BCE. There is no doubt that the sun moves across the terrain so simply recording the movement in reality does nothing since that is a known given scientific fact. The Sun moves, and if you are looking at it from a stationary point the movement is not only noticeable but predictable.

If there was no compensation as shown on the video then the only time one could shoot straight would be High Noon when there was no moving shadow.
