How Gemini reads prompts

Gemini's image tools work from natural-language descriptions and follow-up instructions. A precise first prompt reduces back-and-forth and keeps the result close to your reference.

PromptLens analyzes subject, composition, lighting, color, materials and mood, and writes it as a natural paragraph you can paste in and then adjust.

Tips

A minimalist product shot of a glass perfume bottle on a pale stone pedestal against a soft beige backdrop. Diffused light from the upper left creates a gentle highlight along the glass and a soft shadow to the right. Neutral, elegant and calm.
