Prompting Basics
A strong image prompt follows: Subject + Setting + Style + Lighting + Composition + Technical
A laptop on a minimal white desk showing a dashboard UI,
soft directional lighting from the left, shallow depth of field,
clean commercial photography style, 16:9 aspect ratio, 4K
Common mistakes:
- Too vague ("a business image") — add specific details
- Forgetting aspect ratio — always specify dimensions
- Requesting complex text — use overlays instead for anything beyond short headlines
- No style direction — "photorealistic," "flat illustration," "3D render"
