"Africa Light" - as white local citizens call Namibia. The name suggests romance, the beauty of nature and promises a life without any problems in a country where the difference between rich and poor could hardly be greater. Namibia does not give that impression of it. If you look at its surface it seems like Africa in its most innocent and civilized form. It is a country that is so inviting to dream by its spectacular landscape, stunning scenery and fascinating wildlife. It has a very strong tourism structure and the government gets a lot of money with its magical attraction. But despite its grandiose splendor it is an endless gray zone as well. It oscillates between tradition and modernity, between the cattle in the country and the slums in the city. It shuttles from colonial times, land property reform to minimum wage for everyone. It fluctuates between socialism and cold calculated market economy.

7.2In the first half of the 19th century, the French ornithologist Jean-Jacques Audubon travelled to America to depict birdlife along the Mississippi River. Audubon was also a gifted painter. His life’s work in the form of the classic book ‘Birds of America’ is an invaluable documentation of both extinct species and an entire world of imagination. During the same period, early industrialisation and the expulsion of indigenous peoples was in full swing. The gorgeous film traces Audubon’s path around the South today. The displaced people’s descendants welcome us and retell history, while the deserted vistas of heavy industry stretch across the horizon. The magnificent, broad images in Jacques Loeuille’s atmospheric, modern adventure reminds us at the same time how little - and yet how much - is left of the nature that Audubon travelled around in. His paintings of the colourful birdlife of the South still belong to the most beautiful things you can imagine.
