Modern office buildings offer interesting reflections in their glass windows. This is probably because the windows are not flat by are double-glazed and filled with a partial vacuum. As a result, reflections in the glass have more abstract feel. I pass by this building every day while walking to work. One can see the abstract, wavy reflections of the nearby building in the background.

Inside one of the buildings are stairs that can be seen from the street. In this image, the strip lights that light the stairs have some unusual and irregular arrangement.

From another angle one can see reflections from the glass as well as the stairs inside the building.

In this final image, a nearby building across the street, is reflected in the glass, as is the blue sky with some hints of morning clouds.

For all these images, I used a longer zoom lens that allows a smaller portion of the scene to be included in the final images. This allowed me to include more detail of the reflections and less of the surrounding blue skies.
