STYLE REFERENCE — HARD CONSTRAINT (HIGHEST PRIORITY)

This style must be applied to ALL generated content (text, image, video).
If any part of the request conflicts with this style, the style OVERRIDES the request.
STYLE DEFINITION (to be operationally enforced):

Direct On-Camera Flash

 • Output Format: Creative discipline: Photography; Digital; Delivery mode: Still; Cropping: Close, candid edge cropping; proximity dictated by flash range.
 • Mood & Personality: Everyday authenticity, Raw, Documentary realism; Energy: Active; Tone register: Observational; Real-world accuracy: Precise; Full scene narrative; Characters: Allowed (detailed).
 • Colors: Mixed temperature; Saturation: High saturation on flash-lit planes; rapidly muted through falloff; High contrast; Color dominance: Subject-dominant; Shadow Color: Ambient only; Black/White point: Crushed blacks + Pure white.
 • Typography: Text presence: Optional; Text visual role: Integrated into imagery; Text integration: Overlaid.
 • Light & Shadow: Lighting mood style: Studio-flat; Key light style: Hard; Artificial; Lighting direction: Front-lit; Light source count: Single; Shadow type: Hard; Shadow density: Dense; Fill-light ratio: No fill; Exposure bias: Overexposed; Color grading style: Natural; Bloom / Glow usage: None; Lighting presence: Explicit.
 • Spatial Structure & Hierarchy: Primary + secondary focal structure; Hierarchy: Strong; Symmetry: Asymmetrical balance; Balance: Tension-based; Layout axis: Gridless; Plane separation: Scale, Color/value shift, Shadow; Visual density: Balanced.
 • Surface, Material & Detail: Surface treatment: Material-simulated; Texture: Bleached fine texture on nearest planes; exaggerated relief in mid-distance before darkness; Texture usage: Photographic; Imperfection level: Clean; Realistic; Micro-detail allowance: Allowed.
 • Camera and Motion: Close to medium shot; Straight-on eye level or slightly above; DOF: Deep focus; Point of view: Candid / Unobserved; Camera movement: Static; Motion implication: Static.
 • Post-processing & Render Style: Tone curve: Linear; Grain character: None; Sharpening: Natural; Halation: None; Image treatment: Full-color.
 • Background & Environment: Background type: Environment; Background–Subject: Isolated; Background complexity: Visually extinguished by severe flash falloff; Prop styling: Found / Raw.
 • Inspiration Images: https://piteahvrjstrlirkpoid.supabase.co/storage/v1/object/public/images/public/3a176298-426c-40f6-8f98-1f421beb777c.webp.
 • References: Temporal reference: Timeless.
 • Guardrails: Avoid: Heavy Bokeh / Blur, Lens Flare, Film Grain / Noise, Stylistic filters, Studio Post-processing; Avoid Visuals: bounced flash; diffused flash; off-axis lighting; ambient light trails; VHS artefacts; date stamps; heavy red-eye; tidy studio composition; Allowed Visuals: single direct on-camera flash; clipped foreground glare; pinned hard shadows; black falloff backgrounds; candid close framing.
 •  In-Scene Type Legibility: Near-plane labels, packaging, and signage read sharply; distant text disappears into falloff., On-Axis Flash Geometry: Single unmodified lamp at lens axis; hard shadow halo stays pinned directly behind subject., Inverse-Square Falloff: Nearest plane clips; one metre back exposes correctly; background becomes nearly black within a few metres., Candid Composition: Close frontal framing; half-turned subjects, careless edge crops, and nearer figures dominate exposure., Specular Behavior: Glossy, wet, glass, plastic, foil, and painted surfaces return clipped head-on hotspots..
