On the occasion of the bicentenary of heliography (1826–2026), invented by Joseph Nicéphore Niépce, this exhibition revisits the origins of photography as a writing of light. Taking Mallorca as a pioneering laboratory in industrial photographic techniques, the exhibition traces the technical and aesthetic evolution of the medium through the Casa Planas Archive. From early negatives to tourist postcards, photography in Mallorca is conceived as a key driver in shaping the island’s tourist imaginary.
