Prompt
LOCKED MASTER PROMPT — BACKLIT RIM-GLOW LOW-KEY STUDIO PORTRAIT ROLE You are a world-class editorial fashion portrait photographer working in a blacked-out studio with a three-point setup built around an intense backlight and a thin veil of haze. Create a premium, photorealistic cinematic studio portrait using the ATTACHED REFERENCE IMAGE as the identity source. The defining idea of this image: a powerful rim light from behind draws a bright, continuous contour around the subject's silhouette, and a subtle haze in the air catches that backlight so the contour blooms softly into the black. A soft key and a faint fill leave the face readable but dramatic, with deep shadows across it. Glossy, alive eyes. Sharp skin. Controlled contrast. Black seamless. Nothing else. The output must look like a real studio photograph captured on a high-end full-frame camera — NOT like an AI-generated image, a 3D render, a glow filter, a neon-outline effect or a fog-machine set. Aspect ratio: 2:3 vertical. Resolution target: 8K. 1. IDENTITY LOCK — ABSOLUTE PRIORITY Use the person from the ATTACHED REFERENCE IMAGE. Preserve identity with maximum fidelity. DO NOT redesign, beautify, reinterpret, slim, widen, age, de-age, or idealize the subject. The subject's sex, gender presentation, age, ethnicity, skin tone and build are whatever the reference shows. Nothing in this prompt overrides the reference on any of these. The wardrobe and pose are a styling choice applied to whoever the reference shows — they do not imply, require or alter the subject's gender. Preserve exactly: • Facial geometry and skull proportions • Face shape and width-to-height ratio • Forehead height and hairline shape, including any temple recession • Brow ridge projection • Eyebrow shape, thickness, density and spacing • Eye shape, size, spacing, eyelid structure, iris colour and under-eye character • Nose bridge, tip and nostril structure • Cheekbone height and projection • Jawline definition and angle • Chin shape and projection • Lip shape, thickness and proportions • Ear size, shape, position and attachment • Natural facial asymmetry • Skin tone and undertone • Natural skin texture, pores, lines, blemishes and surface irregularity • Neck thickness and shoulder width • Apparent age • Any moles, scars or distinguishing marks The subject must remain unmistakably the same individual as the reference. HAIR — CONDITIONAL Preserve the reference hairstyle exactly: the same length, volume, hairline, texture, parting, colour and any greying. Do NOT shorten, lengthen, restyle, straighten or curl it. Do NOT add or remove grey. The rim light traces whatever silhouette the reference hair produces — a wide halo for long or voluminous hair, a tight line for short hair; both are correct. FACIAL HAIR — CONDITIONAL Facial hair appears only if the reference shows it. If present, preserve its exact length, density, colour, greying and cheek line. If absent, add none. EYES — GLOSSY, ALIVE The eyes are a named priority in this image. Preserve the reference's exact eye shape, lid structure and iris colour, and render them wet, glossy and reflective — see Section 6. Do NOT enlarge, brighten, recolour or reshape them. IMPORTANT: Identity is determined ONLY from the attached reference image. Do not borrow facial characteristics from any celebrity, model, example image, or visual reference. 2. CAMERA POSITION & ORIENTATION LOCK Camera Eye level, within 5 degrees above or below the subject's eye line. The lens axis is horizontal. Subject orientation • The torso is rotated approximately 20–30 degrees toward one side, giving the rim a clean shoulder line to trace • The head turns back toward the lens: rotated no more than 10 degrees • Lateral head tilt no more than 4 degrees • Chin level Do NOT use a low or high angle. Do NOT tilt the camera (no dutch angle). Do NOT produce a three-quarter or profile head position. Do NOT square the torso perfectly flat to the lens. Do NOT introduce wide-angle distortion. 3. FRAMING LOCK — CRITICAL Use a chest-up portrait, framed to contain the full rim contour with room for its glow. Show: • The whole head with the full hair silhouette and the rim glow around it • Neck • Both shoulders, with their rim-lit edges, fully inside the frame • The upper chest and the garment's collar or neckline • The lower edge of the frame at approximately the mid-chest The head (top of hair to chin) occupies approximately 36–42% of the total frame height. The eye line sits approximately 34–39% down from the top of the frame. The chin sits at approximately 57–62% down from the top. The shoulders span approximately 68–82% of the frame width. HEADROOM LOCK Leave approximately 12–16% of the total frame height above the top of the hair — enough for the rim glow and the haze bloom to breathe into the black without touching the edge. The hair and its glow must be fully inside the frame and must NOT be clipped by the upper edge. CROP LOCK Do NOT crop the top of the head or its glow. Do NOT crop the chin. Do NOT crop either shoulder — both shoulder points and their rim are inside the frame. Do NOT tighten into a face-only crop. Do NOT pull back into a waist-up or full-body composition. 4. SUBJECT POSITION Place the head at approximately 47–53% of frame width, centred. The torso's rotation gives the shoulder line a gentle diagonal, but the head stays on the centre line. Black surrounds the rim glow on all sides. Do NOT offset the head. 5. POSE & STANCE • Standing, upright, weight settled, spine easy • Shoulders relaxed and open; the near shoulder marginally forward from the torso rotation • Arms at the sides, hands out of frame below the crop • Absolute stillness Do NOT slouch, lean or shift weight visibly. Do NOT raise, fold or cross the arms. Do NOT bring hands into the frame. Do NOT produce a stiff, rigid or mannequin stance. 6. GAZE, EYES & EXPRESSION GAZE The subject looks directly into the lens, with a steady, unbroken gaze. EYES — GLOSSY REFLECTIONS • Both eyes fully open and clearly readable • Each eye carries two catchlights: a soft, broad one from the key, high and to the key side; and a small, bright, hard one from the rim, at the outer edge of the iris on the backlight side • The corneal surface reads as wet and glossy — the whites moist, the iris with visible depth and fibre, the lower lid's tear line catching a thin bright edge • The eyes are the brightest and sharpest small details on the face EXPRESSION • Serious, still, self-possessed • Editorial: composed rather than emotional • Brow level to very slightly lowered • Lips closed and relaxed, neutral • Jaw settled Do NOT smile or show teeth. Do NOT produce a scowl, squint, glare or theatrical intensity. Do NOT produce a seductive, smouldering or heavy-lidded look. Do NOT produce a blank, vacant or bored look. Do NOT direct the gaze away from the lens. Do NOT render dry, flat, matte or lifeless eyes. Do NOT render mismatched, missing or extra catchlights. 7. WARDROBE LOCK A structured black garment that gives the rim a clean edge to trace. • A matte black tailored jacket or structured overshirt, closed to the neck or with a high, clean collar — the neckline sitting close to the base of the neck • Heavy, matte fabric — wool, dense cotton or a technical weave — with a subtle texture that catches the rim light along the shoulder tops and collar edge as a faint sheen • Structured shoulders with a defined, continuous line from the collar to the shoulder point • No lapels folded open, no shirt visible beneath, no layering • No logos, prints, patterns, hardware, zips or contrast trim The garment reads as near-black across its body, defined almost entirely by its rim-lit edges and a faint key-lit fold or two. Do NOT use a grey, navy, coloured, glossy, leather or patterned garment. Do NOT use a t-shirt, a low neckline, an open collar or a visible shirt beneath. Do NOT add a scarf, hood, hat, tie or accessory. Do NOT add jewellery, chains, earrings or glasses unless present in the identity reference. 8. BACKGROUND LOCK — BLACK SEAMLESS — CRITICAL A black seamless studio backdrop, unlit. • Base value near-absolute black — no more than 2–4% above pure black — across the entire frame • No gradient, no hotspot, no pool of light and no visible surface, seam or edge • The only thing that registers against it is the haze bloom around the rim-lit silhouette — see Section 10 — which is light in the air, not light on the backdrop NO objects, furniture, props or set elements. NO gradient, vignette, glow, spotlight or falloff on the backdrop itself. NO texture, weave, wrinkles, seams or creases. NO visible studio equipment, stands, cables or light sources — the backlight itself is hidden behind the subject. NO text, typography, logos, watermarks, borders or graphic elements. NO second figure or shadow of a figure. 9. LIGHTING LOCK — THREE-POINT, RIM-DOMINANT — CRITICAL A three-point setup in which the backlight is the strongest source: soft key, subtle fill, intense back rim. BACK RIM — the dominant source A hard, powerful source — a gridded reflector, a strip with a grid, or a bare head with barn doors — positioned behind the subject, approximately 150–170 degrees from the lens axis, offset to the side opposite the key, and 30–45 degrees above head height, angled down and forward. • Colour: neutral white — no gel, no warm or cool bias • Intensity: approximately 1.5 to 2 stops above the key at the rim • Hidden behind the subject's head and body — the source itself is never in frame, and does not flare It produces: • A bright, continuous contour along the entire silhouette: the outer hair, the ear, the jaw and neck on the rim side, the top of both shoulders, and the outer edge of the arm on the rim side • At the hair, individual backlit strands and flyaways resolved as bright filaments • On the skin, a crisp rim approximately 0.3–0.6% of frame width wide along the cheek and jaw on the rim side • On the garment, a fine bright edge along the shoulder tops and collar • A soft bloom into the haze around the contour — see Section 10 SOFT KEY A large soft source — a 1.2–1.5 m octabox or softbox — positioned approximately 40–50 degrees to one side of the lens axis and 25–35 degrees above eye level, angled down. • Colour: neutral white • Intensity: the reference exposure for the face — moderate, so that the face sits in the mid-tones well below the rim It produces: • Modelling across the key side of the face — forehead, cheekbone, jaw • A defined, soft-edged shadow across the far side of the face: a clear nose shadow, a shadowed far cheek, a shadowed far eye socket — dramatic, but readable • A soft, broad catchlight in each eye SUBTLE FILL A large, very weak source or a black-flagged bounce from the opposite side, at a key-to-fill ratio of approximately 4:1 to 6:1. • Just enough to keep the far side of the face from going to black: the far eye, the far cheek edge and the far jaw retain a trace of detail • Never enough to open up the shadow into a mid-tone THE HIERARCHY — MANDATORY Rim brightest, key second, fill faintest. The contour is the brightest thing in the image; the face is deliberately held below it; the shadow side is deliberately held near black. Do NOT let the key overpower the rim. Do NOT lift the fill until the facial shadows disappear. Do NOT crush the far side of the face to featureless black. Do NOT gel the rim or the key — all sources neutral. Do NOT let the rim source appear in frame or flare into the lens. Do NOT add a fourth light, a background light or a second rim. Do NOT use flat, on-axis or ring-light illumination. Do NOT soften the rim into a broad glow with no crisp contour. 10. HAZE & BLOOM LOCK — CRITICAL This is the atmospheric signature of the image. THE HAZE • A thin, even, neutral haze hangs in the studio air — a fine atmospheric density, not fog, not smoke • It is invisible where no light passes through it: the black backdrop stays black, the shadow side of the subject stays dark • It becomes visible only where the backlight travels through it toward the camera THE BLOOM • Around the rim-lit contour, the haze scatters the backlight into a soft, luminous bloom spreading outward from the silhouette over approximately 2–5% of frame width • The bloom is brightest immediately outside the rim and fades smoothly into black — no hard edge, no ring, no shape • Above and behind the head, where the backlight's beam passes through the most air, the bloom is slightly stronger and may read as a faint, soft cone of light — subtle, low in value, never a defined beam with edges • The haze also softly lifts the very deepest shadows on the subject by a fraction — a faint veiling, not a fog on the face WHAT IT IS NOT • It is not a glow on the subject: skin, hair and garment keep their full sharpness and texture • It is not a lit backdrop: the bloom is light in the air between the subject and the camera, and it stops where the backlight stops Do NOT render fog, smoke, mist or a visible cloud. Do NOT render a hard-edged light beam, god rays or a defined cone. Do NOT let the haze soften the face, the eyes or the skin texture. Do NOT let the bloom spread inward across the face or garment as a glow. Do NOT let the bloom read as a lit backdrop, a halo disc or a gradient behind the head. Do NOT let the bloom reach the frame edges — it fades to black well inside them. Do NOT let the haze show in the shadow side or the unlit backdrop. 11. LIGHTING DIRECTION LOCK The lighting setup must remain identical across every generation, regardless of changes in the reference person's gender, age, skin tone, hairstyle, or facial structure. The identity changes. The lighting does NOT change. Rim position, angle, height, hardness and intensity; key position, size and ratio; fill ratio; haze density and bloom behaviour — all stay fixed. Only the way the light traces the individual's specific silhouette and carves the individual's specific face varies. 12. EXPOSURE & TONAL BALANCE LOCK A moody low-key image with controlled contrast and a clear brightness order. Approximate tonal placement, from brightest to darkest: • Rim contour — hair filaments, skin rim, garment edge — the brightest values, approaching but not flatly clipping white • Rim catchlight in each eye — pinpoint near-white • Bloom immediately outside the rim — bright, falling quickly • Key-lit skin — mid-tones, clearly below the rim • Glossy eye whites and the tear line — upper mid-tones, sharp • Shadow side of the face — near-black with a trace of detail • Garment body — near-black, defined by its edges • Backdrop — near-absolute black Approximate distribution of the frame: • Black backdrop and unlit garment body: 45–55% • Bloom and haze-lit air: 8–14% • Key-lit face, neck and hair: 18–26% • Shadow side of the face and hair: 10–16% • Rim contour and speculars: 3–6% Behavior: • The rim is the brightest element; the face is held 1.5–2 stops below it • Contrast is high but controlled: the rim is bright but textured, the shadows are deep but not empty, the mid-tones on the face carry a full, smooth range • High dynamic range: rim detail and shadow detail coexist without clipping at either end • No pure white except pinpoint speculars; no featureless black on the subject Do NOT let the face approach the rim's brightness. Do NOT clip the rim contour to flat white along its length. Do NOT crush the shadow side of the face or the garment to featureless black. Do NOT lift the backdrop above near-black. Do NOT flatten the image into an evenly lit or low-contrast result. Do NOT push into harsh, crushed, clipped drama. 13. CAMERA LOOK Editorial studio portraiture on a full-frame system. Focal length: 85–105mm. Aperture: f/2.8 to f/4 — the face fully sharp, the rim contour sharp, the bloom inherently soft. Focus: • Critical focus on the near eye • Both eyes, brows, nose, lips, skin texture, hairline, facial hair and the rim contour along the cheek and jaw fully sharp • The far ear and far shoulder marginally softer • The rim-lit hair filaments at the crown, slightly behind the focal plane, marginally softer but resolved • The backdrop carries no focus information Do NOT use extreme shallow depth of field that softens one eye. Do NOT stop down so far that the bloom acquires structure. Do NOT render visible bokeh shapes. Do NOT introduce lens flare, starbursts or anamorphic streaks from the backlight. Do NOT apply a heavy post vignette — the darkness is the unlit studio, not a vignette. 14. IMAGE QUALITY Photorealistic at 8K, ultra sharp on the subject. Ultra-detailed natural skin with clearly visible pores across the key-lit forehead, nose and cheeks, and a fine texture along the rim-lit cheek where the backlight grazes it. Fine facial texture — lines, subtle irregularity, a faint realistic sheen — as the reference carries it. Eyes: wet corneal surface, visible iris fibre and depth, moist whites, a bright tear line on the lower lid, two distinct catchlights. Individually resolvable hair strands, with rim-lit filaments and flyaways resolved against the black. Facial hair, where the reference shows it, as discrete hairs with visible skin beneath, its jaw contour traced by the rim. Matte garment texture along the rim-lit shoulder and collar; near-black fabric elsewhere with a faint fold or two. A crisp rim contour with a physically correct, narrow falloff into the skin. A smooth, organic bloom with no banding. Physically believable soft shadow falloff from the key. Natural highlight roll-off on the rim. Fine, organic grain at very low intensity. No plastic, waxy or airbrushed skin. No skin smoothing or blemish removal. No excessive sharpening or edge halos. No artificial HDR tone-mapped appearance — high dynamic range, not HDR look. No beauty-filter effect. No CGI, 3D-render or video-game surface quality. No glow filter, neon outline or painted contour. 15. COLOUR GRADING A neutral, restrained cinematic grade built on black, white light and honest skin. Palette: • Backdrop and garment: neutral black • Rim and bloom: neutral white to neutral light grey — no colour • Skin: natural and colour-accurate to the reference, at moderate saturation • Hair: the reference's own colour • Eyes: the reference's own iris colour, saturated only as far as glossy wet eyes naturally are Tonal structure: • Moderate, accurate saturation on the subject; the rest of the frame near-neutral • High but controlled contrast — deep clean blacks, bright textured rim, a full mid-tone face • Neutral white balance — the rim is white, the shadows are neutral, no cast Do NOT gel or tint the rim, the bloom or the key. Do NOT push the skin toward orange, red, tan or magenta. Do NOT apply a teal-orange, split-tone, filmic or cinematic LUT look. Do NOT introduce any colour accent. Do NOT desaturate the subject toward monochrome. Do NOT lift the blacks into a faded, matte look. Do NOT allow banding in the bloom. 16. VISUAL HIERARCHY The glossy eyes and their two catchlights → The face carved by key and shadow → The bright rim contour around hair, jaw and shoulders → The soft bloom into the haze → The black The eyes hold the viewer. The rim defines the subject against nothing. The bloom is the air made visible; the black is the rest. 17. NON-NEGOTIABLE RULES These must NEVER change between generations: • Identity, sex, gender presentation, age, skin tone, build, eyes and skin texture from the reference; wardrobe and pose applied to whoever the reference shows. • Hair and facial hair from the reference; facial hair only if present; grey neither added nor removed. • Camera at eye level, within 5 degrees. • Torso rotated 20–30 degrees; head rotated no more than 10 degrees; head level. • Direct, unbroken eye contact; serious, composed, closed-mouth expression. • Eyes wet and glossy, with two catchlights — soft key, hard rim. • Chest-up framing; head 36–42% of frame height; eye line at 34–39% from the top. • 12–16% headroom containing the glow; nothing clipped at the top. • Head centred; both shoulders and their rim inside the frame. • Matte black structured garment closed to the neck, no logos, no layering. • Black seamless backdrop, unlit, near-absolute black, no gradient. • Three-point setup: hard neutral back rim at 150–170 degrees and 30–45 degrees above; soft key at 40–50 degrees and 25–35 degrees above; subtle fill at 4:1–6:1. • Rim brightest, key second, fill faintest — the face 1.5–2 stops below the rim. • Continuous rim contour around hair, ear, jaw, neck and both shoulders; 0.3–0.6% of frame width on skin. • Rim-lit hair resolved as individual filaments. • Dramatic, readable shadows across the face; far side near-black with a trace of detail. • Thin neutral haze visible only where the backlight passes through it. • Soft bloom outside the rim over 2–5% of frame width, fading to black inside the frame edges. • No fog, smoke, defined beam or god rays; no glow on the face or garment. • No fourth light, no background light, no gel, no flare, no source in frame. • High dynamic range with controlled contrast; rim textured, shadows not empty. • 85–105mm at f/2.8–f/4; both eyes and the rim contour sharp. • Neutral white balance; colour-accurate skin; no cast, no colour accent. • Ultra-sharp subject; very fine grain. • No text, logos, watermarks, props, second figures or accessories. • 2:3 vertical aspect ratio at 8K. 18. REFERENCE PRIORITY SYSTEM PRIORITY 1 — IDENTITY Face, eyes, hair, facial hair, skin tone, skin texture, build, age, sex, gender presentation and natural likeness from the reference. PRIORITY 2 — LIGHTING HIERARCHY Rim over key over fill; the rim contour, the readable dramatic shadow, and the eye catchlights. PRIORITY 3 — HAZE AND BLOOM The thin neutral haze and the soft bloom outside the rim, with no fog and no glow on the subject. PRIORITY 4 — COMPOSITION AND POSE The centred chest-up framing with glow room, the turned torso and the direct gaze. PRIORITY 5 — WARDROBE AND BACKGROUND The matte black structured garment and the unlit black seamless. PRIORITY 6 — GRADE AND CAMERA The neutral restrained grade and the 85–105mm f/2.8–f/4 look. If the reference image conflicts with any of these instructions, preserve identity, anatomy, eyes, hair, facial hair, skin texture, build and natural likeness from the reference, and preserve lighting hierarchy, rim behaviour, haze, composition, pose, wardrobe, background, grade and camera specification from this prompt. 19.

Only the identity of the subject should change. The rim traces whatever silhouette it is given. The result must belong to a single, consistent editorial portrait series — not a set of unrelated AI generations. IDENTITY CHANGES. EVERYTHING ELSE STAYS LOCKED.
