Generate a bright, clean, airy image with a strong sense of negative space and breathing room around any subject: the subject enters as a close-up main form from the bottom of the frame, fairly large in scale, with edges that may be slightly cropped, so the eye first lands on the subject's rising posture, extending silhouette, or motion toward the light source, then is caught by the large empty backdrop color above. The background is not decoration but a whole expanse of high-brightness, low-noise, slightly gradient glowing color field, occupying the main area, staying ventilated, clean, with a summery light mood; colors are extracted from the subject's own material, season, emotion and narrative, mapped into a large bright base color, a small amount of subject structural color, clear light-and-dark layering and a minimal amount of accent color, keeping high brightness, clean tonal steps, controlled saturation and soft contrast, not copying fixed color codes, and not applying grey-yellow, aged, smoky or muddy treatment. The subject's surface uses natural strong light and soft reflection, highlights nearly transparent, shadows used only to build form, never lowering the overall airiness. In the negative space above, place a set of thin hand-written title lines or symbols as if written out by light, in white or a light bright info color derived from the subject, with relaxed strokes, curves and pauses, as if floating in the air; beside it, extremely small caption text forms a slight tilt or vertical reading rhythm, the information layer light, sparse, restrained, serving the spatial scale rather than stealing focus from the subject. The overall finish should feel like a fresh editorial photoshoot: the low angle brings openness, the subject and the empty color field form a clear top-bottom weight relationship, the text leaving memory like a gesture in sunlight, the image bright, clean, soft but not empty. —————— Avatar use: vertical 3:4, an adult female half-body portrait approaching the lens from the bottom of the frame, shoulders, neck and chin slightly cropped, gaze lifted toward the window light above. Written in the negative space: handwritten subtitle “Today I am bright,” on the right in tiny type “profile avatar / light makeup / white shirt.” Character temperament: clean, confident, relaxed, with no heavy studio-shot feel.
