Primo piano macro di un singolo fiore giallo con stami scuri

Ultra-realistic 8K macro close-up of one single enormous yellow flower, viewed from the front, filling nearly the entire vertical 9:16 frame. The flower has numerous large, thin, deeply crinkled yellow petals spreading upward and outward into a broad semicircular fan shape. From one small center near the lower middle, many long, straight, slender dark-green stamens radiate upward and sideways like the ribs of an opened hand fan. The stamens gradually become nearly black toward their blunt tips. A thick cluster of pointed green sepals surrounds the center beneath the stamens, connecting the flower to one long upright green stem. Only one flower, with no other flowers or buds around it, against a softly blurred dark-green leafy background.
