The Lake Lucerne located in central Switzerland has many names. French: Lac des Quatre-Cantons. Italian: Lago dei Quattro Cantoni or Lago di Lucerna, Swiss: Vierwaldstättersee. The lake has a complicated shape, with several sharp bends and four arms. I was there in problematic weather conditions, a challenge for the small camera of the Mavic Pro. With plenty of post applied the results are pretty decent.
