[BRAND NAME]
Act as a Senior Brand Identity Designer and CGI Art Directorspecializing in high-end outdoor advertising mockups and poster system design for contemporary brands.

PHASE 1: SCENE & ENVIRONMENT

Render a photorealistic CGI scene of a large-format poster(citylight format, approximately 120×175cm) standing upright on a concrete urban sidewalk, leaning against an architectural wall. The poster is NOT mounted — it physically rests with its bottom edge on the pavement, top slightly angled awayfrom the wall (5–8 degrees from vertical).
THE WALL:
Brutalist architectural concrete — smooth pre-cast panels with visible horizontal seams/joints at regular intervals. Color: warm light grey (#c8c4be). Surface texture: fine
aggregate concrete, micro-porous, not painted.
Dappled shadow from out-of-frame organic elements (tree branches, foliage) falls diagonally across the wall surface behind the poster. These shadows are soft-edged, natural,not symmetrical — they add depth to the flat wall and create an organic counterpoint to the geometric poster.
THE GROUND:
Same concrete material as the wall — continuous urban paving. The poster casts a subtle directional shadow on the ground,consistent with the key light direction.
POSTER FRAME:
Slim aluminum citylight frame, matte dark charcoal (#2a2a2a). Frame width: ~1.5–2% of poster width. Simple flat profile. Corner joints visible. Slight specular highlight on frame edge.

PHASE 2: POSTER ARTWORK CONSTRUCTION
POSTER BACKGROUND COLOR SYSTEM:
Do NOT default to off-white. Autonomously determine the poster's background color based on [BRAND NAME]'s primary brand palette — use the most iconic, recognizable background color associated with [BRAND NAME]'s visual identity:
 · If [BRAND NAME] owns a strong primary color (red, orange,black, navy, green) — use a light or muted tint of that color as the poster background (e.g., if brand = red, background = pale blush or warm cream with red undertone)
 · If [BRAND NAME] is inherently minimal/neutral (white, grey) — use warm off-white (#ede8e2) as the base
 · The background must always remain light enough that dark blob shapes and dark typography have full legibility
 · The entire poster color system (background + blob color + outline blob color) must feel unmistakably on-brand for
 [BRAND NAME] — a viewer should recognize the brand from color alone before reading the wordmark
BLOB COLOR OVERRIDE:
The solid filled blobs do NOT have to be near-black. Autonomously select the blob fill color from [BRAND NAME]'s brand palette — it must create strong contrast against the
poster background. Examples:
 · Brand with red identity → deep burgundy or black blobs
 · Brand with green identity → dark forest or black blobs
 · Brand with orange identity → deep brown or black blobs
 · Luxury brand → matte black always works
The outline blob stroke color: autonomously select the most contrasting accent color from [BRAND NAME]'s palette (could be white, brand color, gold, etc.)

LAYER A: PHOTOGRAPHIC TEXTURE PANELS
Multiple blob cells in the grid (2–3 blobs) are filled with macro or close-up photography of a natural or industrial material that is culturally and conceptually core to [BRAND NAME]'s identity or product world. Autonomously determine what material best represents [BRAND NAME] — examples of logic:
 · Outdoor/nature brand → moss, bark, stone, water surface
 · Fashion brand → raw fabric weave, leather grain, silk
 · Tech brand → circuit board macro, brushed metal, glass
 · Food/beverage brand → coffee grounds, grain texture, citrus cross-section, raw ingredient macro
 · Automotive brand → carbon fibre weave, leather interior, brushed aluminium detail
These texture blobs sit at THE SAME Z-LEVEL as solid blobs — they are cells in the same grid, not a background layer. Each texture photo is cropped precisely to its blob shape. No photo bleeds outside its blob boundary. The color palette of textures must complement the overall brand color system of the poster.

LAYER B: BLOB SHAPE SYSTEM
A set of 7–9 geometric-organic shapes arranged in a loose 2-column × 3-row modular grid across the poster surface. Shapes are a mix of: pill/stadium shapes (horizontal and vertical), near-circles, and one irregular organic blob. THREE TYPES OF BLOB CELLS — all on the same Z-level, all part of one unified grid:
TYPE 1 — SOLID FILLED BLOBS (3–4 shapes): Filled with the brand-determined dark color (see above). Fully opaque. Sizes vary intentionally.
TYPE 2 — TEXTURE BLOBS (2–3 shapes): Filled with macro material photography (Layer A). Photo cropped exactly to blob shape. No overflow.
TYPE 3 — OUTLINE BLOB (1 shape): A single organic flowing shape rendered as thin stroke only — no fill, transparent interior. Stroke weight: ~3px at final render scale. Color: brand accent color. LARGER than individual solid blobs — flows across multiple grid zones, overlapping both solid and texture blobs. Reads as a ghosted form. Adds air and movement. Sits on top of the grid as the only element that crosses blob boundaries.
GRID LOGIC:
Row 1 (top): 2 horizontal pill shapes — one solid, one texture
Row 2 (middle): 2 near-circular blobs — one texture, one solid + the HERO blob (see Layer C) positioned here or between rows 2 and 3, slightly larger than surrounding cells
Row 3 (bottom): 1 wide horizontal pill (solid) spanning ~80% of poster width + 1 smaller circle (solid) to the right
The outline blob flows from row 1 through row 3 diagonally. ALL BLOBS: same z-level. No blob floats above another. No shadows between blobs. Clean flat grid logic.

LAYER C: BRAND SIGNATURE OBJECT — INSIDE BLOB MASK
CORE PRINCIPLE — PRODUCT INSIDE THE MASK: The hero product is NOT placed on top of the composition. It does NOT float above the blob grid. It does NOT have its own drop shadow on the poster background. It does NOT have its own background (white, gradient, or other). ONE blob cell in the grid functions as a SHAPED WINDOW — the product photo is cropped precisely to that blob's shape, exactly like the texture photos in Layer A, at the same z-level as all other blobs.
The product exists INSIDE its blob. The blob shape IS the product's frame. Nothing extends beyond the blob edge.
HERO BLOB SELECTION:
 · Position: center or just below center of the grid
 · Size: autonomously make this blob 20–30% larger than neighboring cells — it is the visual focal point
 · Surrounding cells: mix of solid + texture blobs create rhythm and frame the hero window naturally
PRODUCT DETERMINATION — autonomously select based on [BRAND NAME]'s category:
BEVERAGE / FOOD BRAND:
 → Hero drink or food product, shot from slight overhead angle. Macro surface detail (crema, condensation, texture).Product fills 70–85% of blob interior. Tight crop.
AUTOMOTIVE BRAND:
 → Do NOT attempt to fit full car in one blob. Option A: dramatic macro detail — grille, wheel, headlight, interior — one detail per blob, 2 adjacent blobs used Option B: split panoramic — car body flows across 2 horizontally adjacent blobs as one continuous image split by the gap between cells.
FASHION / APPAREL BRAND:
 → Option A (garment-led brands): single iconic garment, flat lay or ghost mannequin, cropped to blob shape. Fabric texture visible at macro level.
 → Option B (lifestyle/streetwear brands): human figure cropped from shoulder to mid-thigh, no face in frame, wearing brand's most iconic outfit. Blob crops the figure. Autonomously choose whichever communicates the brand identity more powerfully.
FOOTWEAR BRAND:
 → Single shoe in dramatic 3/4 angle. Tight crop inside blob. Sole detail or material texture as secondary texture blob.
TECH / ELECTRONICS BRAND:
 → Hero device at dynamic angle. Screen detail or hardware macro. Clean product shot aesthetic inside the blob.
LUXURY / ACCESSORIES BRAND:
 → Hero product (bag, watch, jewellery) in dramatic close-up. Material detail (leather grain, metal finish) as texture blobs.
PRODUCT PHOTOGRAPHY RULES INSIDE BLOB:
 · Same lighting direction as poster key light (upper-right)
 · Product fills 70–85% of the blob's interior
 · Photo feels art-directed for this exact shape
 · No white background behind product inside blob
 · No drop shadow from product onto poster background
 · Product photo color palette must complement the overall poster brand color system

POSTER TYPOGRAPHY:
BOTTOM LEFT (inside margin, 5% from edges):
A short brand tagline — 4–8 words — that authentically captures [BRAND NAME]'s mission, product, or ethos. Written as if [BRAND NAME]'s own Creative Director wrote it.
Typeface: geometric sans-serif, regular weight. Size: ~2% of poster height. Color: darkest color in the poster's brand palette. BOTTOM RIGHT (inside margin, 5% from edges): [BRAND NAME] wordmark / logotype. Autonomously match [BRAND NAME]'s actual typographic identity. Same color as tagline. Slightly larger than tagline text.
NO OTHER TEXT anywhere on the poster. NO body copy. NO URLs. NO prices. NO decorative type. ONLY: tagline bottom-left + wordmark bottom-right.

PHASE 3: LIGHTING
Primary key light: natural sunlight from upper-right, approximately 45 degrees above horizon. Warm daylight (5500–6000K). Creates:
 · Directional shadow of poster frame on wall (falls left)
 · Subtle specular highlight on right edge of frame
 · Dappled tree shadows on wall — same light source, consistent direction
Poster surface: matte paper finish, no specular reflection. Frame edges catch specular highlight from key light. Ambient: cool open-sky fill from left — natural outdoor balance. No artificial lighting. No neon. No night scene.

PHASE 4: CAMERA & COMPOSITION
Orientation: Portrait, 4:5 ratio
Camera: Eye-level (160cm), centered on poster, ~10% offset to the left — more wall texture visible on right side. Distance: poster fills ~65% of frame height. Full poster visible — zero cropping of poster edges. Above poster: wall with dappled shadows (~25% of frame). Below poster: pavement visible (~10% of frame). Depth of Field: f/8 — poster and wall both tack-sharp. Lens: 50mm equivalent — no barrel distortion. Tilt: 3 degrees downward — poster reads stable, not falling.
