Why this prompt works
Deliberate openness is the strength here: it asks only for a high-quality vertical science-popularization encyclopedia image driven by a single [Theme] placeholder. By fixing nothing but format and quality bar, it lets the model compose whatever encyclopedia content suits the subject slotted in.
Variations to try
- ·Fill [Theme] with the solar system, human anatomy, or volcanoes.
- ·Request a horizontal layout instead of the vertical orientation.
- ·Add a specific language requirement for any on-image text.
Style & lighting notes
Only two cues are fixed: vertical orientation and an encyclopedia-style science-popularization look; every other visual choice is delegated to the model based on the chosen theme.
