Buenos Aires´ Sunset

A friend of mine invited me to take a coffe in a restaurant, he told me it was on the 23th floor of a building in the Buenos Aires´ downtown, then I asked him if I could bring my tripode, what I wanted was to take three photos of the same frame but different exposure, He told me it was not allowed then I took my bag with the camera and the lenses and went to the meeting. When I got there my friend was taking a coffe and enjoying the view, I set my camera on my bag and I started to take the photos, I decided to shoot in av mode with a cheap remote shutter I had, and after a couple of coffe cups and a lot of photos and meanwhile I enjoyed the sunset, I got the three photos I wanted to blend.
To create this photography I Blended the three pictures I liked the most, one for Highlights, one for sky and the last one buildings.
