Vertical composition, fixed shot, the camera steadily follows the main subject of the large watercolor brush, with the focus smoothly adjusting to follow the brush's movement. The camera keeps the focus on the brush tip and the paper as the brush, dipped in clear water and light blue paint, boldly spreads water and paint across the paper. The water and paint quickly diffuse and blend, creating natural watercolor effects. As the brush moves, the water and paint flow across the textured watercolor paper, with its grain and depth clearly visible. The blending of water and paint creates a lively sense of movement, and the paper slightly ripples due to moisture absorption, showcasing realistic physical effects. As the camera pans horizontally, the shot sweeps across the upper half of the paper, clearly presenting the details. The background is dark, with professional studio lighting precisely highlighting the details and layers. The scene is captured in high-definition (1080p), with high resolution and high image quality, using a high bitrate for professional cinematic-grade visuals, ensuring every detail is crisp and clear, with rich and delicate lighting effects, dynamic and full of artistic energy.
