River tide A short time-lapse film captures the rhythmic dance of the Sapucajuba River in the Amazon, as it rises and falls with the ocean’s tides. In less than a minute, golden-lit waters silently flood the forest’s edge, then retreat—a daily pulse shaping life in this ecosystem. More than a natural phenomenon, these tidal cycles weave into ancestral knowledge and the routines of riverside communities, revealing the quiet poetry of an Amazon in constant motion. Bárbara Baleixe
