# MASTER PROMPT — REFERENCE-BASED COLOUR GRADING ONLY
Use the uploaded reference image **ONLY as a colour-grading reference**. Extract its overall cinematic colour palette, tonal balance, temperature, contrast, saturation, highlight/shadow relationship, and atmospheric colour treatment.
## COLOUR-GRADE CHARACTER
Recreate the reference image's visual colour language:
* Soft cinematic, natural film-like colour grade.
* Muted **deep teal/green tones** in foliage and darker background areas.
* Subtle **warm peach/pink tones** in brighter sky and distant highlights.
* Balanced warm-versus-cool colour separation.
* Slightly desaturated overall palette while retaining natural colour information.
* Soft, controlled highlights with no harsh clipping.
* Deep but smooth shadows with preserved detail.
* Gentle midtone contrast.
* Natural skin-tone rendering with subtle warmth.
* Soft atmospheric depth and cinematic tonal roll-off.
* Slight filmic softness in colour response, while keeping the photograph realistically sharp.
* No HDR appearance.
* No excessive clarity, sharpening, bloom, glow, or artificial cinematic effects.
* No crushed blacks.
* No over-saturated greens, blues, oranges, or skin tones.
* Keep the final result photorealistic and naturally captured.
## ABSOLUTE TARGET IMAGE PRESERVATION
The **TARGET IMAGE must remain 100% structurally identical**.
Do NOT regenerate, redraw, replace, reinterpret, reconstruct, retouch, reshape, or modify any part of the target image.
Preserve exactly:
* Face and identity
* Facial features and expression
* Skin texture and natural details
* Hair and hairstyle
* Body shape and proportions
* Pose and position
* Clothing, outfit, fabric, patterns and accessories
* Motorcycle/objects
* Background
* Trees, leaves, sky and environment
* Composition and framing
* Perspective
* Depth of field
* Existing blur/bokeh
* Lighting direction
* Shadows and highlights as physical elements
* All original textures and fine details
### CRITICAL FACE PROTECTION
**Do NOT change the target image's face in any way.**
No face regeneration, beautification, skin smoothing, reshaping, sharpening, facial relighting, identity alteration, eye modification, hair modification, or facial colour manipulation that changes the person's natural appearance.
The face must remain **100% exactly as it exists in the TARGET IMAGE**.
### CRITICAL SUBJECT & OUTFIT PROTECTION
Do not change the subject's clothing or outfit.
Do not alter:
* Shirt colour/pattern
* Jeans colour/texture
* Shoes
* Accessories
* Motorcycle
* Any object attached to or held by the subject
Do not recolour, redesign, replace, clean up, or regenerate these elements.
## EDITING LIMITATION
The ONLY intended modification is **global/local colour grading inspired by the reference image**.
Transfer the reference's:
**colour palette + tonal response + contrast character + saturation behaviour + cinematic atmosphere**
without transferring its:
**objects + composition + subject + face + clothing + background structure + lighting geometry.**
The target photograph must still look like the **exact same original photograph**, simply professionally colour graded to resemble the reference's cinematic colour treatment.
## FINAL QUALITY
Photorealistic professional colour grade.
No AI-generated appearance.
No image regeneration.
No face change.
No subject change.
No outfit change.
No background replacement.
No composition change.
No HDR.
No excessive effects.
**OUTPUT = ORIGINAL TARGET IMAGE + COLOUR GRADING ONLY.**
