I am sharing in The Photos of the Readers of La Vanguardia this photograph, taken from the beach of Gavà, in the Baix Llobregat, in which we can see a plane that seems to be punctured by the Torre de Collserola.
An optical illusion leads us to perceive reality in various ways. It can be of a physiological nature, associated with the effects of excessive stimulation in the eyes or the brain (brightness, color, movement, etc).
Or also of a cognitive nature, in which our knowledge of the world intervenes (such as Rubin's vase in which we perceive two faces from the side or a vase indistinctly).
Many artists have taken advantage of optical illusions to give their works a magical aspect, depth, ambiguity and contrasts. Photography does not escape this type of effect and perspective also comes into play.
In this case, it gives us the feeling that the plane was punctured by the tip of the Torre de Collserola, located in the Turó de la Vilana, at 445.5 meters above sea level, near Tibidabo.
This tower has a viewpoint on the tenth of its 13 floors, from which it is possible to obtain a complete view of the city of Barcelona and its surroundings, sometimes even up to 70 kilometers away. It was designed in 1992 by the English architect Norman Foster and is one of the icons of the Catalan capital.
