“Subtle Fragments” is a small tribute to the greatest Portuguese architect, Álvaro Siza, whose works stand out for their discretion. Taken at the headquarters of the Iberê Camargo Foundation, Siza's only work in Brazil, the photographs avoid the iconic exaltation of the building. They prefer to subtract from it abstract fractions that, due to the graininess, suggest pencil drawings. The sequencing of the images, sometimes bathed in sunlight or artificial lighting, symbolically addresses the formal and rhythmic articulation that occurs between the exterior and interior spaces of the building.
