bricole di informazioni

Prima dell’ avvento della fotografia, l’unico metodo utilizzato per una fedele riproduzione dell’ architettura, interni ed esterni, era con il disegno a mano.

Before photography the only way to “reproduce” architecture, interior and exteriors, was by drawing it. 

E’ la geometria (dal greco geo-terra/metria-misura) una delle scienze più antiche, un ramo della matematica che si occupa di misure, forme, posizione relativa delle figure e le proporzioni nello spazio.

It’ s geometry (from the Greek geo-earth/metria-measurement) one of the oldest sciences, is a branch of mathematic, that concerne size, shape, relative position of figures and the proportion of space.  

Ed è attraverso la geometria, che è stato possibile “ritrarre” l’ architettura utilizzando le giuste proporzioni e le giuste misure.

It is thorough geometry that it has been possible to “portray“ architecture by using the right proportions and lenghts.

Ed è anche la conoscenza della geometria che ci permette di avere, con la macchina fotografica (banco ottico, o con un medio formato o una reflex 35mm con obbiettivo basculante) una ripresa di un esterno o un interno di architettura utilizzando le giuste proporzioni.

It is through the knowledge of geometry that you can have, with a camera (large format, or a medium format or a 35mm with a tilt and shift lens) a shot of an architecture exterior or interior with the right proportions.

Ed è da qui che parte il mio blog, usare la macchina fotografica per riprodurre l' architettura. 
Questo blog non è un MANUALE e sicuramente posso anche non essere "precisa"  in quello che scrivo. Sono ben accetti INTERVENTI costruttivi.
Ho studiato architettura e lavorato in studi di architettura per 10 anni prima di dedicarmi esclusivamente a questo ramo della fotografia (da 10 anni sono una fotografa professionista specializzata in fotografia di architettura di interni ed esterni).

le proporzioni nella fotografia di architettura

L' equilibrio "visivo" nella fotografia di architettura di esterni ed interni è fondamentale per far si che vengano mantenute le giuste proporzioni all'interno dell'immagine. Immagine che deve "rimandare" alla realtà di ciò che è stato fotografato.

La fotografia di architettura è intesa come oggettiva documentazione. Deve quindi mantenere le proporzioni all' interno dell'immagine.

sectio aurea

Where can we find the Golden Ratio?

The golden ratio is present in nature, for example there are various types of shells (for ex. the Nautilus) that have a spyral form that reminds of the the sectio aurea.

Meaning and use of the Golden Ratio

The golden section is a line segment divided according to the golden ratio:

the total length a + b is to the longer segment a as a is to the shorter segment b.

The golden section comes from the Latin: sectio aurea. The meanings are many: divine proportion, divine section, golden proportion, golden cut, golden number, the golden ratio is often denoted by the Greek letter phi. (Phidias (500 BC - 432 BC), a Greek sculptor and mathematician, studied phi and applied it to the design of sculptures for the Parthenon)
In the Renaissance, many artists and architects have proportioned their works to approximate the golden ratio—especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter is the golden ratio.

Architecture and Golden Ratio

Studies of  the Acropolis (Greece – Athens) , including the Parthenon, conclude that many of its proportions approximate the golden ratio.  For example the Parthenon's facade as well as elements of its facade can be circumscribed in the golden rectangle.

Considering that some of the classical buildings and their elements are proportioned according to the golden ratio, this might indicate that their architects were aware of the golden ratio and consciously employed it in their designs.

For example though, a geometrical analysis of the Great Mosque of Kairouan (Tunisia - Kairouan Governorate) by Boussora and Mazouz, reveals a consistent application of the golden ratio throughout the design. It is found in the overall proportion of the plan and in the dimensioning of the prayer space, the court, and the minaret. They also examined earlier archaeological theories about the mosque, and demonstrate the geometric constructions based on the golden ratio by applying these constructions to the plan of the mosque to test their hypothesis.

On the other hand, Swiss architect Le Corbusier, famous for his contributions to the modern international architecture, centered his design philosophy on systems of harmony and proportion. Le Corbusier explicitly used the golden ratio in his Modulor system for the scale of architectural proportion. He saw this system as a continuation of the long tradition of Vitruvius, Leonardo da Vinci's "Vitruvian Man", the work of Leon Battista Alberti, and others who used the proportions of the human body to improve the appearance and function of architecture.

Another Swiss architect, Mario Botta, bases many of his designs on geometric figures. Several private houses he designed in Switzerland are composed of squares and circles, cubes and cylinders. In a house he designed in Origlio, the golden ratio is the proportion between the central section and the side sections of the house.

In a recent book, author Jason Elliot speculated that the golden ratio was used by the designers of the Naqsh-e Jahan Square (Iran- Isfahan) and the adjacent Lotfollah mosque.

It is allthough possible that the architects in the ancient history used their own sense of good proportion, and that this has led to the use of proportions that closely approximate the golden ratio. Retrospective analyses can always be questioned on the ground that the if one chooses the points from which measurements are made or where to superimpose golden rectangles, these choices affect the proportions observed.
