A close-up, detailed image of a dahlia flower. The style is impressionistic, with a soft focus and a sepia-toned palette, emphasizing the subtle gradations of light and shadow within the petals. The flower is centered in the image, with its petals cascading outward. The petals are large, delicate, layered and textured, displaying intricate folds and curves. The focus is on the flower's structure and the interplay of light. The background is pure white, isolating the flower and drawing the viewer's attention to its delicate beauty. The lighting creates a soft, ethereal atmosphere. The image's style is more about capturing the essence of the flower than a precise photographic reproduction.
