This is the riverfront side of the Renaissance Center, which also happens to be the headquarters for General Motors. There is a certain irony to this, since the RenCen was built in the '70s with major funding from the Ford family and Ford Motor Company. When originally built the building was almost a fortress, with large berms in the front which blocked it from the rest of the city, and the back was also pretty imposing. GM has done a nice job opening up the building to make it more accessible from the street. I took this shot during the Detroit edition of Scott Kelby's Worldwide Photowalk.
The image was mostly processed in Lightroom 2.0 with a bit of final processing in Photoshop CS3.
