Extreme close-up, shot from a low 30-degree angle, of finely sifted matcha powder in a shallow matte ceramic bowl. A bamboo whisk's tines have just lifted from the surface, leaving a swirl of vivid green foam with a few tiny bubbles. Individual powder grains and the soft ridges of the foam are sharp in the foreground, and the background falls into a creamy blur. Soft side light from a window at left picks out the velvety texture and a faint sheen on the bubbles. The palette is grassy greens, with a worn wooden table in warm brown and a hint of pale daylight. The mood is calm and focused, with a clean, airy, natural feel. The green is the vivid, near-electric tone of fresh matcha. No text, no logos.
