Example

## Try an example

- Photorealistic wide shot of a rooftop greenhouse at dusk on top of an old brick building: rows of tomato vines and hanging ferns under warm grow lights, condensation on the glass panes, a small wooden workbench with clay pots and a watering can. Through the glass, a city skyline with office windows lighting up under a violet sky. 24mm lens, deep focus, warm interior against cool exterior, crisp leaf and glass detail.
