This particular garage is above Downtown Crossing in Boston, pretty close to where I work. The 10th floor is the top floor, and it's completely open to the air. Some of the garages I've been in are the bottom few floors of an office building, and while they may offer some good views of older architecture, they're a bit limiting as far as skyline views go.
I will have to head back to this garage one night with a tripod to get some of the buildings. There's a great panoramic view of the nearby office buildings that would look pretty amazing through a really wide lens.
For this shot I went back to the digital camera and used the Canon 17-40 lens at 40mm with a circular polarizing filter on to darken the sky out a bit.
While I was up on the roof I also took a few shots of the action below. The downtown crossing area is pretty busy on a nice day during the lunch hour. I made a gimmicky fake tilt-shift miniaturization shot out of one of the images. Sure it's kitschy, but fun nonetheless. This is outtake #1:
On my way back from the garage I spied this pooch hanging out of a car, so I took a shot. He's outtake #2:
