Dark background, with precise studio lighting focusing on an artist’s worktable, neatly arranged with watercolor tools, including a brush, paint palette, and water container. The camera smoothly and steadily zooms in, focusing on a brush with leftover watercolor color, a faint sheen glistening on the surface of the brush. The brush is gently placed into transparent water, with the clear water surface slightly rippling as the brush touches it. Blue paint slowly diffuses, gradually blending across the surface. The shot remains stable, with no camera shake, ensuring that every detail is clearly visible. The water surface, paint diffusion, and lighting effects are finely presented in high definition (4K), with natural texture and smooth transitions in the lighting. The scene lasts for approximately 10 seconds, delivering a quick yet refined visual effect.
