Palacio de Cristal
The history: The Palacio de Cristal ("Crystal Palace") is a structure located in Madrid's Retiro Park built in 1887 and made almost entirely of glass set in an iron framework on a brick base, which is decorated with ceramics. Its cupola makes the structure over 22 metres high. It is no longer used as a greenhouse, and is currently used for art exhibits.
The shooting: At night, when empty, the structure looks incredibly elegant and mysterious at the same time. I was shooting with very long exposure and a tripod due to the poor lightning.
Post-production: I used several filters to add some special effects to the already appealling subject.
Gear: Canon 5dmarkIII, Lense; Canon 24-105mm at 24mm, Iso; 100, f/8, 25 seconds exposure
