For the Abstract Challenge (Theme : B&W). This shot was made at nighttime, through a circular window, aiming at the glass door of the opposite building in a narrow street. If you look well, you will see the handle of the glass door. Through that door, there is a brightly lit entrance hall, and a metallic high chair with a modern design. In order to increase the graphical neatness, I have strongly increased the contrast of the picture, in order to dim the slightly visible joints of the ceramic tiled floor in the original shot.
