Gemini Image (Nano Banana) Prompt Generator

Gemini Image (Nano Banana) understands full sentences, so the prompt reads like a photographer's brief: subject, setting, lighting, composition, mood and where the image will be used.

Every prompt is built from the same modular parts — role, task, context (your audience and details) and output format — then rendered in the style each AI follows best. Change the AI in the drop-down and the same request is rewritten instantly.

• Describe the scene conversationally — Gemini can keep editing the image across turns.
• Upload a reference photo to keep a product or person consistent.
• State the aspect ratio explicitly.

Choose a prompt type for your task; each comes with an expert role, context rules and an output format:

• Photorealistic image — for example “an elderly fisherman mending nets on a wooden pier”.
• Illustration / concept art — for example “a floating city above the clouds at sunset”.

Example output for Gemini Image (Nano Banana):

Create an image of an elderly fisherman mending nets on a wooden pier, set in a natural environment that suits the subject. Style: photorealistic, high detail, shot on a 50mm lens. Lighting: soft natural light. Composition: rule of thirds, shallow depth of field. Mood: authentic and calm. Details: early-morning mist, muted blue tones. It will be used for an editorial magazine feature, so use a 3:2 aspect ratio. Avoid: blur, distortion, extra fingers, text, watermark.
