Type:
Ultra–photorealistic macro render of a heavily aged silver coin, cinematic low-key lighting, realistic oxidation, scratches, and ancient patina buildup, vertical or square composition.
🏛️ Subject:
The face of the person from the attached image, shown in profile, engraved and embossed into the surface of a centuries-old silver coin.
(Use the uploaded photo as the absolute and complete 100% facial reference. Do not alter, stylize, or modify facial features. Keep the face perfectly identical, natural, and realistic as in the reference.)
The engraving must appear subtly worn, with soft relief edges, oxidized contours, and visible aging marks — as though minted long ago and naturally eroded by time.
⚙️ Material & Surface Details:
The coin is made of ancient oxidized silver, exhibiting deep aging effects:
Dark silver and blackish-gray coloration, with patches of heavy tarnish and corrosion.
Softly rounded edges, chipped marks, and irregular wear consistent with centuries of handling.
Visible micro-scratches, dents, and abrasions across the surface.
Oxidized relief: darkened recesses with lighter silver highlights on raised portions.
Dirt and dust deposits within engraving grooves.
Matte, rough reflection, almost completely non-glossy except for faint metallic highlights.
Color palette: oxidized silver-gray to black tones (#4A4A4A → #D3D3D3) with light reflections of #BFBFBF on raised areas.
Surface realism: fine corrosion pitting, micro patina cracks, uneven texture, and true metallic imperfections.
The entire coin should look authentically old, handled for decades or centuries, and untouched by restoration.
✒️ Inscription & Border Design:
Around the circular edge, engraved in refined uppercase serif type:
→ “Beata Clélia Merloni”
Between and around the text, include engraved stars and simple ornamental flourishes, forming a faint decorative border.
The lettering should appear heavily aged, partially faded, and darkened by oxidation, yet still readable when light strikes at an angle.
Some letters may be worn and uneven, enhancing historical realism.
💡 Lighting Setup (Cinematic Macro Studio):
Key Light: 45° upper-left — cool desaturated light (~4700K) for cold silver tone.
Fill Light: 20° right — very soft, low-intensity fill to maintain shadow depth.
Rim Light: Dim cool reflection from below, barely outlining the coin edge.
Accent Light: Narrow, focused beam over the portrait to reveal worn relief and texture.
Reflections: Subtle, irregular, emphasizing oxidized texture rather than shine.
Depth of Field: Shallow — sharp focus on engraved face and main inscription, gradual blur at the coin’s outer rim.
Lighting Mood: Cold, mysterious, and historical, with chiaroscuro depth and contrast.
📷 Camera & Rendering Parameters:
Lens: 85mm macro prime
Aperture: f/2.8 (cinematic shallow focus)
ISO: 100
Shutter Speed: 1/125
Lighting Model: PBR aged silver shader with oxidation and corrosion layers
Render Quality: 8K ultra macro realism
Environment: Low-reflection HDRI with soft gradient background
Focus Plane: Centered on portrait engraving and upper border text
Composition: Coin perfectly centered; background softly fading into shadow.
🪞 Background:
Minimal dark matte background, cold desaturated tone (#0E0E0E → #1A1A1A) with soft vignette and subtle fog gradient.
No distractions — the coin must stand out as a historical relic illuminated by a single studio light.
🎬 Mood & Style:
Deeply historical, sacred, and contemplative.
Authentic museum artifact realism, resembling a relic discovered after centuries.
Cold silver tone, oxidized patina, tactile surface imperfection.
Cinematic low-key lighting, poetic atmosphere, emotional depth.
Suggests holiness, legacy, and time’s passage.
