There was an article/video tutorial on the fstoppers home page today on how to do these black and white "fine art" architectural images by Fred van Leeuwen. I've always liked these types of images but have never done any myself, so I decided I would try out his technique on some of my own older images.
For this I added in a long exposure sky from another image of mine.
Edited in lightroom and then further post production in photoshop.
