I found the photographs by this artist in the library and found them very interesting. I thought they were little models at first but then realized that it was taken from an ariel view and using the lens to create a somewhat distorted perspective.
I found some information on the web about Olivo that mentions his use of a tilt-shift lens to create these miniature looking effects in urban settings. He also is taking the photos from a helicopter. He has taken a lot of different photos in various cities using this technique.
Many of the photos are of famous buildings and also famous natural landmarks I was also very impressed with the ones that were of Niagara Falls the distorted perspective in these in particular work very nicely in the photos.
