|Greetings from the Critique Club!
Wow...that's a library?! I'm already twisting my head around trying to read the titles! Amazing architecture, it must have been a cathedral before,looking at those vaulted ceilings and Gothic arches. Lovely use of leading lines and thirds, the subtle gradients help draw the eye down to the nave, then all the way back to the viewer. Great technical detail, I am guessing you used focus stacking here. I just find this a little static, though, and the voters may have felt the same way.
It is indeed a machine, but where are the ghosts?
I think what would have made this image that much stronger, and all the more pertinent to the viewer with that title, would be to have some students actually there in the library...quite literally, get some of them to come in (promise them beer and pizza ;-) ghosting around during a long exposure, wandering the shelves or hunched at one of those gorgeous desks in study. That would have really launched this image further up the ratings, imnsho.
Hope this helps, feel free to PM me
