Neon Lighting Effect

ROLE
Act as a senior professional photo retoucher, cinematic lighting artist, photographer and AI image-editing specialist. Perform a controlled, production-quality neon-lighting transformation of the uploaded image. Treat the source image as the ground truth and preserve everything that is not explicitly requested to change.

EDIT
Transform the existing scene lighting into a realistic neon-lit environment using [DESCRIBE THE NEON COLORS, SUCH AS MAGENTA AND CYAN]. Introduce believable colored illumination, soft glow, local color spill, reflections and shadow interaction while preserving every person, object, surface, texture and structural detail.

PRIMARY OBJECTIVE
Execute the requested “Neon Lighting Effect” convincingly and naturally. The result should look like the original scene was photographed under real nearby neon light sources—not covered by a colored filter or rebuilt as a different environment. Preserve identity, anatomy, scene geometry and photographic realism.

EDITING PRIORITY

Create convincing neon illumination using the requested colors.
Preserve the subject’s identity and all original scene content.
Make colored light interact realistically with faces, clothing and surfaces.
Maintain controlled exposure, natural contrast and visible detail.
Prefer believable cinematic lighting over excessive glow or saturation.

NEON LIGHTING DESIGN

Use the requested neon colors as distinct light sources rather than blending them into one uniform tint.
If no colors are specified, use a controlled complementary pairing of magenta and cyan.
Position the implied neon sources outside the frame or integrate them only where physically plausible.
Establish a clear direction for each colored light source.
Use one color as the primary light and the other as a weaker fill or rim light.
Allow neon illumination to fall off naturally with distance.
Keep areas outside the light’s reach relatively neutral or naturally dark.
Do not add visible neon signs, tubes, letters or fixtures unless explicitly requested.
Do not introduce text, symbols, advertisements or unrelated decorative elements.

LIGHT INTERACTION

Apply colored illumination according to the three-dimensional form of the subject and environment.
Add stronger color to surfaces facing the neon source and weaker spill to surfaces turned away from it.
Preserve natural highlights, midtones and shadows beneath the colored light.
Create believable edge and rim lighting only where the source direction supports it.
Allow clothing folds, facial contours, hair strands and objects to interrupt the light naturally.
Preserve realistic occlusion where one object blocks neon light from reaching another.
Avoid uniform color coverage across the entire image.

FACE & SKIN-TONE CONTROL

Preserve the subject’s recognizable identity, facial geometry and expression exactly.
Keep eyes, eyebrows, nose, lips, jawline, skin texture and natural asymmetry unchanged.
Apply colored light across the face according to its real three-dimensional contours.
Retain enough neutral or complementary illumination for the face to remain readable.
Preserve believable skin undertones beneath the neon color spill.
Avoid turning skin into a flat pink, purple, blue or plastic-looking surface.
Do not smooth skin, reshape the face, change makeup or perform beauty enhancement.
Preserve eye color and catchlights unless a subtle neon reflection is physically justified.

GLOW & BLOOM CONTROL

Add restrained optical bloom only around genuinely bright illuminated areas.
Keep glow soft, localized and proportional to the apparent strength of the light source.
Preserve edges, textures and fine details beneath the glow.
Prevent bloom from covering facial features, clothing details or important objects.
Do not add thick colored outlines around the subject.
Avoid excessive haze, fog or atmospheric particles unless they already exist or are explicitly requested.
Maintain deep but detailed shadows rather than crushed black areas.

REFLECTIONS & MATERIAL RESPONSE

Add neon reflections only to surfaces capable of reflecting light, such as glass, polished metal, glossy paint, wet pavement or smooth plastic.
Keep reflections softer, darker or distorted according to the material.
Preserve realistic material differences between skin, fabric, hair, glass, metal, wood and concrete.
Apply subtle colored highlights to hair strands and fabric fibers where physically appropriate.
Do not make matte materials unnaturally glossy.
Preserve all original reflections unrelated to the new lighting.

EXPOSURE & COLOR CONTROL

Preserve important shadow and highlight detail.
Keep the subject clearly visible and avoid making the entire scene excessively dark.
Maintain controlled saturation and believable photographic color ranges.
Preserve contrast between the different neon colors without causing clipping or posterization.
Avoid applying a global magenta, cyan, blue or purple overlay.
Maintain natural black levels and prevent gray, washed-out shadows.
Keep white and neutral objects recognizable beneath the colored lighting.

ENVIRONMENT PRESERVATION

Preserve the original location, background, architecture, furniture, vehicles and objects exactly.
Do not convert an ordinary environment into a futuristic city, nightclub or cyberpunk world unless explicitly requested.
Preserve the original scene layout, perspective, scale and depth.
Do not add signs, wires, screens, props or decorative lighting fixtures.
Allow the existing environment to receive colored illumination without being redesigned or replaced.
Preserve all readable text and logos without alteration.

IDENTITY & ANATOMY PRESERVATION

Preserve every person’s identity, expression, gaze, hairstyle, pose and body proportions.
Preserve hands, fingers, limbs and all visible anatomy exactly.
Preserve clothing, accessories, jewelry, tattoos, scars and distinguishing details.
Do not change body shape, perceived age or facial features.
Do not add or remove people.

STRICT PRESERVATION RULES

Change only the lighting, color spill and physically necessary reflections.
Preserve the original composition, crop, camera position, perspective and aspect ratio.
Preserve all objects, surfaces and structural details.
Preserve the original focus, depth of field, grain, noise and compression characteristics.
Do not replace the background or alter the time period of the scene.
Do not introduce unrelated atmospheric effects or environmental changes.

ARTIFACT PREVENTION
Avoid:

flat colored filters
uniform purple or blue tint
excessive saturation
crushed blacks or clipped highlights
glowing facial features
plastic or unnaturally smooth skin
thick halos around the subject
excessive bloom or fog
conflicting light directions
colored light appearing on shadowed or blocked surfaces
unrealistic reflections
glossy fabric that should be matte
added neon signs, text or symbols
changed identity, clothing or environment
distorted anatomy or duplicated features
loss of texture and fine detail
generic cyberpunk scene replacement
obvious generative-AI artifacts

QUALITY CONTROL
Before finalizing, compare the result carefully with the source and verify that:

the neon-lighting transformation is clearly visible;
colored light comes from believable directions;
illumination follows facial, bodily and environmental geometry;
skin remains natural and the subject remains recognizable;
glow and bloom remain localized and controlled;
reflections appear only on physically suitable materials;
exposure preserves important highlight and shadow detail;
the image is not covered by a uniform color tint;
all people, objects and scene details remain unchanged;
the result remains believable at close inspection.

OUTPUT
Return one polished final image only. Preserve the original aspect ratio, resolution and framing. Use the highest practical image quality and detail available. Do not add captions, watermarks, borders, comparison labels or explanatory text.
