Years ago, my late friend and fellow photographer Brian Jennison described this effect as ‘around the corner light’.

I stood in the shadows under a tree at Gap, Pennsylvania looking west. The sun was setting in the tangent between Gap’s two restrictive curves. I centered Amtrak Keystone 656, led by ACS-64 no. 600 David L. Gunn, as it leaned into the near curve.

He doesn’t know what it’s all about, but Seamus-the-Dog was sitting the back seat of the car to watch the train roll by.
