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
- Raincoat wear is described with specific details (patches, buckle corrosion, plastic crackle) not abstract adjectives like 'worn'.
- Lighting specifies direction, source quality (hard vs. soft), and shadow side to achieve the intended chiaroscuro.
- Black-and-white treatment defines tonal range (true blacks, specular highlights) so the model renders a full-range B&W not a faded gray image.
