Nano Banana Pro is renowned for its exceptional image generation consistency, making it an ideal tool for character design workflows. A powerful application of this capability is converting any character image or photo into a comprehensive costume reference sheet for future generations.
Below are two effective prompt strategies to achieve this: a simple method for quick results and a detailed approach for maximum fidelity.
Simple Version
This prompt is effective for quickly establishing a character's layout. It leverages Nano Banana Pro's understanding of visual styles to generate a front and back view, capturing the overall essence without getting bogged down in minutiae.
Analyze the attached image to understand the character and the visual style.
Generate a split-screen image containing two full-body views of this character on a simple color background:
1. **Left Side:** Front view.
2. **Right Side:** Back view.
Aspect Ratio: 1:1
Detailed Version
For professional workflows where accuracy is non-negotiable, this detailed prompt is the superior choice. It explicitly instructs the model to perform "deep feature extraction," ensuring that facial physiognomy, physical attributes, and intricate costume details are mirrored exactly from the source. This method fully utilizes Nano Banana Pro's consistency capabilities to create a reference sheet that is true to the original design.
Analyze the attached image to perform a deep feature extraction of the character. Specifically identify and mirror the following traits:
* **Facial Physiognomy:** Replicate the exact eye color/shape, nose structure, jawline, and facial proportions.
* **Physical Attributes:** Mirror the hair texture, hair color, skin tone, and body type exactly.
* **Costume Details:** Retain the specific texture, material properties, and color palette of the clothing.
Generate a split-screen image containing two full-body views of this character on a simple color background:
1. **Left Side:** Front view.
2. **Right Side:** Back view.
**Visual Constraints:**
* **Aspect Ratio:** 1:1
* **Style Fidelity:** The output must retain the exact visual style, rendering technique, and lighting quality of the source image.
