[Backstory] Geometry. This challenge is about the shapes and rhythms that make up the geometry of our world. Many photographs of any genre have an underlying sense of geometry, but I often like to make this the main subject of my work. I think it’s the most important aspect of a photograph’s success. This could be the patterns of the natural world up close and personal, or the rhythm of your local buildings. The above photograph, “Positive Negative,” depicts the Paula Rego Museum in Lisbon where the sky created an equally strong element of the composition as the building. The image has a totemic quality, softened by the passing cloud. I had waited for this cloud to move into the perfect position within the frame. The colour, light, and form of the image emphasize this geometry.

Tip: Once you have found a good subject that contains an interesting geometry, try to crop tightly into the subject to make an unexpected composition. Your goal should be to create an abstract composition so the image is more about underlying shapes than a literal representation of the subject matter itself — by doing this you create art rather than a snapshot.

For such special city, an equally singular Cathedral was designed and built. On 12th September 1958, the Cathedral’s cornerstone was laid. The Metropolitan Cathedral of Brasilia is an expression of the geniality of the architect Oscar Niemeyer. In 1960, the Cathedral’s structure was finished, and only the 70 m diameter of the circular area and the 16 concrete columns were visible. These columns, having parabolic section and weighing 90 t, represent two hands moving upwards to heaven. The Cathedral was dedicated on the 31st May, 1970. At that time it had already the external transparent window. Four bronze sculptures 3 m high, representing the Evangelists, can be seen at the external square in the entrance of the Temple. These sculptures were made with the help of the sculptor Dante Croce, in 1968. Inside the nave, three sculptures of angels are suspended by steel cables.

The smallest angel has 2,22 m of length and weighs 100 kg. The medium one has 3,40 m of length and weighs 200 kg. The big one has 4,25 m of length and 300 kg weighs. The sculptures were made by Alfredo Ceschiatti, with the help of Dante Croce, in 1970. The nave stained glass is made of 16 pieces of fibreglass. These pieces, in colours of blue, white and brown, were fixed between the concrete columns, in triangles of 10 m of base and 30 m of height. They were painted in 1990 by Marianne Peretti. Having an oval form, the Baptistery has its walls covered by a panel of ceramic tiles painted in 1977 by Athos Bulcão. The local architecture is completed by a bell tower. Its four big bells were donated by Spain.
