Iwan Baan has very interesting, impressive architectural shots.

He has his personal projects as well as his commercial photos on his website.

Good architecture and good images!
On the opennig page image: I like it a lot how the warm light comes in through from the ceiling openning- while blue cool light casts inside from the side window. How those lights coplimentary in such a bright daylight image.
There are many more good compositions and interesting architecture in the gallery.
