Between 2021 and 2024, the body of work titled Tetra was produced from 35 mm slides dating from the 1960s to the 1990s and presented as slide projections. Composed of 243 images in three sets of 81 (Tetra I, II, III), the series reinterprets found photographic material, tracing how images record, circulate and transform across time.

For Tetra AL, selected slides were translated into lithographic prints on pre-sensitized anodized aluminum plates. These industrial plates, designed for short-run offset printing and typically single-use, were retained and repurposed, transforming disposability into longevity. On the reverse side of each plate is a developed negative from another slide, linking the works in a material, visual and conceptual sequence.

The imagery moves between the natural world, the built environment and human life, each suggesting different temporal scales. A recurring square aperture punctuates every image, introducing absence as a structural and perceptual element.

The work reflects on how technological change alters the conditions of photography—from analog selectivity to digital abundance—and how perception, memory and consciousness intertwine in the act of seeing, revealing the unstable and elusive nature of subjective experience.
