Hello! First post. I lurked a bit and this forum looks very interesting for me... I have had a look for this info here but haven't found anything yet, as a Noob, I'm sorry in advance if this has been discussed already... damn let me edit, of course this image is broken.. OK. We know that crepuscular beams are meant to be "in actuality" almost parallel to the path back to the sun... The beams are vertical at the point they face the Earth, and will look converging due to perspective. So when you look at this image... Look at some of the buildings at the extreme edges, and project [their] vertical lines up heavenward... Then compare that vertical with the beam next to it or around it... Is it me, or is there a discrepancy? The view is flat. The verticals are straight up... The sun above should be delivering vertical beams to that area... I know - the sun is off at an angle to their vertical (also due to curvature), but then wouldn't all the beams in the picture look like they had more of a common angle? Why are some beams the "opposite" direction? Then, look at this: The source of these converging lines seem to be the point at which they leave the gap in the branches ITSELF. What else is happening? Some kind of Camera Obscura effect? Or is it just that the sun is so tiny at this distance...? Not intuitive to get one's head around IMO. Refraction effects (Rays in space/vacuum hitting a surface of atmosphere)? Thx!
