## Watch out

- Unlike Nano Banana, exclusions work here when they are short and grouped. (vendor; OpenAI image prompting guide via Director Chair field notes on image prompting)
- A city name gave the wrong city. Describe the materials and the street instead. (measured; Director Chair field notes on image prompting)

## The prompt, in order

1. **What the image is for:** a product photograph, an advertisement, a diagram.
2. **The visible details:** materials, light, colours, medium, scale.
3. **People:** framing of the body, relative size, where they look, what they do with objects.
4. **Text:** the exact words in quotes, with position and type; unusual words and brand names spelled letter by letter.
5. **Exclusions,** short and grouped: no extra text, no watermark, no logo.

## Edits
Change one thing per round and repeat the list of what must stay (identity, layout, light, labels) every round; details drift across repeated edits.

## What we measured (Sep 2026)
A city name drew the wrong city's architecture; name the materials instead (brick with blue stone).
