Generate a bright and clear image with a strong sense of white space and breathing around any theme or subject: the subject enters from the bottom of the frame as a close-up main form, on a relatively large scale, with edges slightly cropped, allowing the gaze to first land on the subject's uplifted posture, stretched silhouette, or movement towards the light source, and then be caught by the large area of empty background color above. The background is not decoration, but a whole field of high-brightness, low-impurity, slightly gradient glowing color, occupying the main area, maintaining a ventilated, clean, and summer-like light-hearted mood; colors are extracted from the subject's own material, season, mood, and narrative, mapped as a large area of bright background color, a small amount of subject structural color, clear light and dark layers, and a minimal amount of accent colors, preserving high brightness, clean color steps, controlled saturation, and soft contrast, without copying fixed color numbers, nor applying grayish-yellow, old, smoky, or muddy treatments. The subject's surface uses strong natural light and soft reflections, with highlights being nearly transparent and shadows only used to establish form, not weighing down the overall sense of air. In the white space above, place a set of thin-line handwritten titles or symbols that look as if written by light, in white or a light bright information color derived from the theme, with relaxed brushstrokes, curves, and pauses, as if floating in the air; on the side, use very small font explanatory text to form a slightly tilted or vertical reading rhythm; the information layer should be light, sparse, and restrained, serving the spatial scale rather than seizing the subject. The overall sense of completion should be like a refreshing editorial photoshoot: the low viewing angle brings a sense of openness, the subject and the empty color field form a distinct top-bottom weight relationship, the text leaves a memory like a gesture in the sunlight, and the image is bright, clean, soft but not empty.
