2. Resolutio
Interactive photochromic diptych — ultraviolet light, photochromic pigment on glass, computer vision
Two glass panels that cannot hold an image for long. When you stop in front of them, your face is captured and written with ultraviolet light onto both. On one, it fades until only white remains. On the other, a stain spreads over it until the face is gone — and then the stain, too, disperses into white.
The work
Resolutio is a diptych that exists only while someone stands in front of it. Two glass panels, 96 × 96 cm each, are coated with photochromic pigment — a material that darkens wherever ultraviolet light touches it and clears again on its own within minutes. When a visitor stops before the work, an infrared camera captures their face in the dark and the same portrait is written, by ultraviolet light, onto both panels at once.
From that moment the two images follow opposite paths. On one panel, the face fades: it loses contrast, thins, and dissolves until the surface is white again. On the other, a stain begins to spread over the face — it darkens, covers the features, and swallows the bust entirely; then the stain itself loosens, disperses, and the panel returns to white. The cycle lasts a few minutes. The work keeps nothing: no image is stored or transmitted.
