“Contrails (short for “condensation trails”) or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets or, if the air is cold enough, tiny ice crystals”. – Wikipedia

Bouwe Brouwer: Postcards from Fryslân (series finalist). “People from Fryslân are looked upon by the rest of the Netherlands as stubborn people. Going back as far as the Spanish occupation, they have a history of resisting authority. Postcards from Fryslân is still an ongoing project – hopefully a lifelong one. When it started, it represented only a collection of places that seemed interesting. Currently, the hope is to cover most of the province, as you never know in advance where the best narratives are. But still, it is all candid, unposed and in the public realm”. (Photo by Bouwe Brouwer/Street Photographers Awards 2021)
