Overview

This skill helps you craft high-quality prompts for Nano Banana Pro image generation. It guides you through clarifying intent, choosing a prompt style, and assembling concrete, model-ready instructions to improve output fidelity. Use it to optimize prompts for photo realism, illustration, infographics, product shots, or character consistency.

How this skill works

I first check for any reference images, existing prompts, or visual examples you provide. Then I ask focused questions to clarify the output type, subject, style, and technical requirements. Based on your answers I select a prompt format and apply proven techniques (narrative, structured, photography terms, negative prompts, aspect ratio, etc.) to construct a ready-to-run prompt. Finally I present the prompt, explain why it was built that way, and offer variations for iteration.

When to use it

• You need a clear, reproducible prompt for Nano Banana Pro image generation.
• You have reference images and want consistent character or style across outputs.
• You want control over photographic terms, lighting, lens, or era-specific aesthetics.
• You are creating educational diagrams, product shots, or multi-panel compositions.
• You want to convert an existing prompt into a more structured or precise form.

Best practices

• Provide reference images and state the role of each (pose, style, color, background).
• Answer core questions first: output type, subject, mood, and technical specs.
• Choose a prompt style that matches your goal (quick narrative vs detailed structured).
• Specify negative prompts and exclude elements you don’t want to appear.
• Include aspect ratio, resolution hints, and any text placement or font preferences.

Example use cases

• Create a magazine-cover portrait with golden-hour lighting and magazine-style text.
• Generate a realistic product shot with white background, 3:4 aspect ratio, and soft studio lighting.
• Produce a character illustration using a reference photo for facial consistency across poses.
• Design an infographic explaining a concept with labeled arrows and simplified diagrams.
• Turn a rough prompt into a structured YAML/JSON prompt for precise control over details.
