Buenos Aires (Argentina) is a south american city greatly influenced by european architecture at the turn of the XXth century. You can find many european-style buildings in the so-called "Paris of South America". This photo was taken in the Güemes Gallery, and it represents the Art Nouveau style. The building was designed by the italian architect Francisco Terencio Gianotti and inaugurated in 1915.
I took this photo hand-held with a wide angle lens (10mm on a Canon 80D). I wanted to highlight the symetry in the composition. It is a HDR (three images) to manage the high contrast and low light conditions. Postprocessing consisted of perspective corrections, saturation and contrast, denoise and sharpening.
