Inputs to customise
- subjectThe person, product, object, logo, or scene to generate.
- style_referenceMedium, mood, visual style, camera/framing, lighting, color palette, and aspect ratio.
- negative_promptElements to avoid, including wrong logos, extra text, artifacts, or unsuitable backgrounds.
Quality checks
- Location is named specifically (city, district, or landmark) — not just 'a city at night'.
- Lighting is described as practical city sources with named color temperatures (sodium-orange, LED-white) — not generic 'night lighting'.
- Camera simulation specifies focal length (24mm) and ISO equivalent to guide photorealistic rendering without HDR halos.
