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 broad horizontal movement across the paper. The brush tip, dipped in clear water and light blue paint, moves boldly and horizontally across the paper, spreading water and paint that quickly diffuse and blend, creating natural watercolor effects. The brush's horizontal sweeping motion drives the water and paint 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 moves, the water and paint create large areas of blending across the paper, with the shot sweeping over the upper half of the paper, presenting the details clearly. 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.
