“Sky Registers” is an ongoing cyanotype case study that documents the shifting colors of the sky in the United Arab Emirates over a full 24-hour cycle, across the seasons of winter and summer. Using light-sensitive cyanotype exposures, the work captures subtle variations in atmosphere, luminosity, and duration translating time and climate into a visual archive. What emerges is both a scientific record and a poetic mapping of celestial rhythms, the intersection of place and light. The project continues the exploration of geography, temporality, and the material translation of the intangible.
