Proof if ever any was needed that most people on a.net dont understand anything about photography. Telephotos, like the 500mm lens "flatten" perspective thus making it appear almost as if there is no space at all between those two aircraft. In reality theres probably easily 1000ft if not more between them, so you can add:

This is one of the best photos I've ever seen! Vertical separation seems smaller that 1000ft. Maybe someone in ATC went into big trouble."

Gorgeous pic. But there's no way that's 1000 feet between them."
