Cold Blue Aesthetic Light Effect

Use the user uploaded image as the exact base reference. Apply a subtle cold blue-ish lighting effect, as if the scene is illuminated by soft screen light reflecting from a laptop or iPhone in a dark room. Lighting & color treatment: Cast a gentle, cool blue-white light onto the subject’s face, skin, and hair Light should feel soft, diffused, and close-range — like a screen positioned just below or in front of the subject Blue tone should be restrained and natural, not saturated or neon Preserve realistic shadow falloff and facial depth; do NOT flatten the image Highlights take on a cool blue tint, especially on cheekbones, under-eyes, nose bridge, lips, and lower jaw Shadows remain neutral-to-cool, with deep blacks preserved for night contrast Very subtle cool color spill onto nearby surfaces (hands, hoodie, laptop edge, background contours if visible) Mood & style: Intimate, quiet, late-night atmosphere Calm, introspective, slightly lonely or focused mood Feels like a candid moment lit only by a laptop or phone screen in the dark Modern fashion/editorial realism, not stylized illustration Quality & realism: Maintain natural skin texture and pores No plastic skin, no over smoothing, no beauty retouch Slight natural noise or very subtle film grain for realism Preserve original sharpness and depth of field Hard rules (must follow): Do NOT change the subject’s face, facial structure, hair shape, body, or expression Do NOT change the pose, camera angle, framing, or crop Do NOT change the outfit or accessories Do NOT alter the background structure or objects Do NOT change the aspect ratio Only apply lighting, color temperature, and mood adjustments Output should look like the original photo realistically lit by a soft laptop or iPhone screen at night — cool, subtle, and cinematic.
