They're beautiful indeed.
The beauty of it is, no Photoshop in those days!
No electronic version of Photoshop, indeed. But they had actual photoshops, with darkrooms, where a good photo technician could do a lot of magic anyway, particularly in black and white. And I've got a feel that that's exactly what happened here.
Not to diminish the beauty of them, but if you look at image four, there's a building in the lower left hand corner who's windows are all consistently far brighter than the brickwork. In daytime. How did that happen?
Also, picture five. Why would the whole main building light up but not the church in the lower right hand corner, or the houses just across the street. Do you really think he waited for the sun to break through a gap in the clouds exactly the size and shape of the walls surrounding that building? And then positioned the aircraft at the right spot as well?
Still, beautiful stuff.
