Vertical split image of University of Havana campus: left shows litter and dull colors, right shows clean lawn, flowers, and bright sky.

Vertical photograph of the University of Havana campus seen from the outside, divided by a clean vertical line like a before‑and‑after slider. On the left side (40%) the campus looks duller, with desaturated colors, some visible trash on the ground (papers, small plastics), neglected green areas and a slightly gray sky, without exaggerating the dirt. On the right side (60%) is the exact continuation of the same scene but clean: no trash, well‑kept green areas, flowers, a more vibrant blue sky and saturated colors, conveying harmony and order. Hyper‑realistic photo style, high resolution, soft natural lighting, clear composition designed for a university campaign about circular economy and sustainability, with a feeling of “improvement” of both the environment and the image quality at the same time.
