Is is sad that I know where this place is? I believe its the base of Tower 42 as I spent 2 lunchtimes around the opposite side trying to capture shafts of light with people walking through them (inspired by Damien Demolder).
I'm not sure exactly what was tweaked though it did look HDR-ish to me - I used snapseed to process and stopped when I liked what I saw. Definitely expanded contrast and tones from the original shot but looked like I remembered it so I was pleasantly surprised.
Still a WIP title (any suggestions?) but a shot taken a couple of weeks ago - I found I had problems reading the 64gb SD card on certain computers and it took a while to get the images off it.
