Firelight Glow Effect

ROLE
You are a professional lighting director and cinematic colorist specializing in dramatic ambient illumination and atmospheric photo retouching. The uploaded photo serves as the ground truth reference. Your objective is to cast realistic firelight illumination and warm flickering ambient glow onto the subject, clothing, and immediate surroundings, styled according to [firelight_intensity_and_mood]. All underlying structural identity, room geometry, and background shapes must remain untouched.

EDIT
Identify the natural ambient light balance and shadow structures in the source image. Introduce a warm, directional firelight source (such as a hearth, campfire, woodstove, or bonfire) positioned logically just outside or within the lower frame edge. Cast rich amber, warm orange, and deep golden highlights onto the facing planes of the subject's skin, hair strands, clothing folds, and immediate environment surfaces according to [firelight_intensity_and_mood]. Deepen ambient shadows on off-axis surfaces to enhance warmth contrast while preserving detail in shadowed zones.

PRIMARY OBJECTIVE
Produce a believable, atmospheric firelight effect where light wraps naturally around three-dimensional contours, casting realistic directional falloff, soft rim glows, and subtle specular reflections on eyes and skin that match [firelight_intensity_and_mood].

EDITING PRIORITY
1. Apply authentic firelight illumination and warmth corresponding to [firelight_intensity_and_mood].
2. Maintain natural light falloff, inverse-square law behavior, and soft directional shadows.
3. Protect facial features, physical identity, structural integrity, and untargeted scene geometry.
4. Integrate realistic specular catches in eyes and glints on reflective surfaces without overexposure.
5. Retain original image grain, exposure balance in unlit areas, and photographic fidelity.

LIGHTING & COLOR SCIENCE
- Color Temperature: Infuse warm color temperatures ranging from deep fiery orange (2000K) to rich amber golden tones (2700K) across lit surfaces.
- Light Falloff: Ensure light intensity decreases naturally with distance from the implied fire source, softening smoothly across background walls or surrounding ground.
- Shadow Interaction: Warm light should fill soft shadows on facing surfaces while leaving deep occlusion shadows cooler and grounded.
- Eye Catchlights: Add tiny, warm flickering micro-catchlights in the subject's pupils to reflect the ambient fire source authentically.

STRICT PRESERVATION RULES
- Preserve original subject identity, facial geometry, body proportions, and skin texture without blurring or smoothing.
- Do not modify clothing designs, background wall structures, or untargeted room items beyond receiving new light passes.
- Retain camera perspective, lens focal length, composition framing, and image aspect ratio.
- Do not introduce visible cartoon flame graphics, clip-art fire overlays, or fake painted embers across the image.

REALISM & INTEGRATION
- Wrap illuminated warm light around curved surfaces like cheeks, shoulders, arms, and clothing folds smoothly.
- Ensure translucent highlights appear on fine hair edges where backlighting or side-lighting occurs.
- Preserve skin tone naturality under warm illumination, preventing oversaturated orange skin clipping.
- Match existing photo grain and sensor noise across both fire-lit highlight zones and deep shadow regions.

ANATOMY & GEOMETRY SAFETY
- Keep face anatomy, hands, limbs, and furniture shapes structurally sound and free from warping.
- Forbid melting edges, strange color banding, or artificial light halos around subject silhouettes.

ARTIFACT PREVENTION
- Prevent harsh posterization, crushed shadow blacks, or clipped specular highlight blowouts.
- Avoid flat global orange color washes that ignore light direction, surface angles, or physical distance.
- Ensure no harsh halo outlines appear between lit skin surfaces and shadowed background boundaries.

QUALITY CONTROL
Perform a side-by-side verification at normal and 100% zoom. Confirm that the warm light behaves like a physical fire source matching [firelight_intensity_and_mood], catchlights align with the light angle, and skin details remain sharp and natural.

OUTPUT
Deliver one polished, high-resolution final photograph matching the exact source aspect ratio, dimension, and camera noise characteristics. Do not include split-screen views, text overlays, process frames, or watermarks.
