the one thing I hate about most HDRs is the glow...
There's not supposed to be a glow.
This one is pretty decent, but there is a small glow on the top of the building and that ruined it for me.
Can you describe in more detail where this "glow" is at? Thanks for the comments.
I think he is addressing the general area at the roof line (archs) on the front of the building, particularly on the left side. Looks a bit like the effect you get from high pass filtering
