Friends, here (again) is Mr. Stancak's overhead of the doorway:

(Once again, please note that the scene is
Darnell, so people are in
different positions to Wiegman, BUT
the light conditions are the same as for Wiegman. And that's all I'm interested in here for present purposes!)
Look at the natural shadowline cast by the west column (=green line). See how
EITHER
far
backOR
close to the
walla person would have to be to be standing in natural shadow.
Now look at Wiegman:

Question! Is it possible for PrayerMAN to be
in natural shadow (i.e. behind the green line) WHILE standing at a spot that allows
simultaneously-----------to Wiegman's POV-----------
a) his
right elbow to show so little distance from the white column
b) his
left elbow to cut across the vertical metal strip back in the corner?
I submit that it is not, and that this means that PrayerMAN in Wiegman cannot be standing in natural shadow--------------he would either be too far from the white column (right elbow) or not cutting across the vertical metal strip (left elbow). You can't have both things we see in Wiegman--------------
unless he's standing somewhere else altogether, somewhere that does NOT take him right inside the green line.
I believe that the disposition of his arms in relation to other markers shows him to be facing forward (NOT turned somewhat, like PrayerWOMAN in Darnell) and standing on the fourth step up, ever so slightly east of Mr. Lewis who is down two steps below him.
I.E.! To make sense of PrayerMAN's coordinates here, we have to understand that he, like Mr. Lovelady, has had artificial shadow added to him. The original, undoctored Wiegman showed him standing in the
same place as in Hughes:
