Getting Improving Style Consistency in Images right takes more than a single prompt. This 4-stage guide covers Diagnose the Wall, Isolate and Fix, Verify the Resolution, and more, breaking the whole process into focused steps where each prompt builds on the last. When Nano Banana ignores or loosely matches a provided style, it leads to frustration as the generated images do not meet expectations. This inconsistency can disrupt a creator's workflow, making it difficult to achieve the desired aesthetic. The following prompts and techniques will help ensure that your images align closely with your intended style and composition. Every prompt is optimized and runs in ChatGPT, Claude, and Gemini.

Diagnose the Wall

Start by identifying the root cause of the style inconsistency. Use these diagnostic steps to isolate the issue.

Test Core Subject

Run a baseline test prompt using only the core subject: '[PLACEHOLDER]'. Analyze the output to determine how the tool interprets this subject in isolation, without any additional descriptors or stylistic influences. Provide insights on any potential misinterpretations or unexpected results.

Diagnose the Wall

Use a Known Reference

Test the following known-working reference prompt: '[PLACEHOLDER] in [STYLE REFERENCE]'. Analyze the output generated by this prompt to determine if the issue originates from your specific prompt or if it is related to the tool's handling of styles. Please provide a detailed comparison of the results.

Diagnose the Wall

Change One Parameter

Change the style preset in your current prompt from '[STYLE A]' to '[STYLE B]' and then run the prompt again. Analyze the output to determine if the style inconsistency still exists, and provide a detailed comparison of the results from both styles.

Diagnose the Wall

Generate Variations

Generate four variations based on the prompt '[PLACEHOLDER] in [STYLE REFERENCE]'. Ensure each variation showcases different interpretations while maintaining the core elements of the original prompt. After generating the variations, provide a brief analysis of the consistency and differences observed among the outputs.

Diagnose the Wall

Compare Against Reference

Compare the generated image to the reference image or description provided. Identify and list specific areas where the generated image deviates from your expectations, focusing on major discrepancies in style, color, or composition. Provide a detailed explanation for each discrepancy noted.

Diagnose the Wall

Isolate and Fix

Now that you have diagnosed the issue, apply these techniques to fix the style inconsistency.

Add Specific Style Descriptors

Rephrase the following prompt to include specific style descriptors: '[PLACEHOLDER] in the style of [ARTIST/STYLE REFERENCE]'. Ensure that the descriptors clearly convey the desired artistic elements and characteristics to guide the AI in generating a more accurate and aligned output.

Isolate and Fix

Incorporate Negative Prompts

Incorporate negative prompts into your description by specifying elements to avoid. For example, use the format '[PLACEHOLDER], avoid [UNWANTED ELEMENTS]'. Explain how these negative prompts will help the AI concentrate on the desired aspects of the style you want to achieve.

Isolate and Fix

Change Model Version

Switch to a different model version for the task of nano-banana-not-matching-reference-image. Evaluate the available options and provide a comparison of their performance in style adherence, including specific examples of how each version improves the output.

Isolate and Fix

Restructure Prompt Order

Restructure the following prompt by placing the subject first and the style last: '[PLACEHOLDER] with [STYLE REFERENCE]'. Explain how this change can improve the clarity and effectiveness of the generated output, and provide an example of the restructured prompt.

Isolate and Fix

Use Custom Style Preset

Isolate the issue with the selected style preset not applying correctly. Use the 'Custom' preset and describe the desired style in detail by completing the prompt: '[PLACEHOLDER] in a [DESCRIBE STYLE] style'. Provide specific examples of how the style should appear visually.

Isolate and Fix

Verify the Resolution

Confirm that the adjustments have resolved the style matching issues with these verification tests.

Generate New Variations

Generate 4 new variations of the image based on the prompt: '[PLACEHOLDER] in [STYLE REFERENCE]'. Ensure that each variation maintains consistency in style and theme, and provide a brief analysis of any differences observed among the outputs.

Verify the Resolution

Compare to Baseline

Compare the new outputs from the nano-banana project to the Stage 1 baseline reference image. Identify specific areas where the style adherence has improved, detailing at least three distinct improvements in style matching and providing examples to support your observations.

Verify the Resolution

Test with a Complex Subject

Run a test using a more complex version of the subject: '[COMPLEX PLACEHOLDER] in [STYLE REFERENCE]'. Analyze the results to determine if the style maintains its integrity and effectiveness when applied to this challenging subject. Provide specific feedback on any discrepancies or areas for improvement.

Verify the Resolution

Lock the Seed

Run the prompt with the seed locked to ensure consistent outputs. Use the following format: '[PLACEHOLDER] in [STYLE REFERENCE]'. After generating the output, analyze whether the changes have stabilized the generation and provide a summary of your findings.

Verify the Resolution

Check Different Aspect Ratios

Check the generated image of '[PLACEHOLDER] in [STYLE REFERENCE]' at different aspect ratios. Select various options from the dropdown menu and analyze how the style consistency changes with each composition. Provide a detailed comparison of the results for each aspect ratio tested.

Verify the Resolution

Prevent Recurrence

To avoid future style matching issues, use these reusable templates and techniques.

Base Prompt Template

Create a prompt using the following template: '[PLACEHOLDER] in the style of [STYLE REFERENCE]'. Ensure that the [PLACEHOLDER] is specific to the content you want to generate, and adapt the [STYLE REFERENCE] to match the desired artistic or stylistic influence. This will help maintain consistency in future generations of your content.

Prevent Recurrence

Negative Prompt Bank

Create a negative prompt bank that lists common unwanted elements in image generation. Include at least five specific examples, such as 'avoid [UNWANTED ELEMENT 1], [UNWANTED ELEMENT 2], [UNWANTED ELEMENT 3], [UNWANTED ELEMENT 4], and [UNWANTED ELEMENT 5]'. Explain how each element can disrupt style consistency and suggest ways to incorporate this bank into your prompts effectively.

Prevent Recurrence

Seed-Locking Workflow

Establish a seed-locking workflow to ensure consistent image generation results. Always lock the seed when using '[PLACEHOLDER] in [STYLE REFERENCE]' to prevent variations in the output.

Prevent Recurrence

Style-Consistency Checklist

Create a style-consistency checklist for ensuring uniformity in generated images. Include the following steps: 1. Confirm that the correct style preset is selected for the project. 2. Utilize specific style descriptors to guide the generation process. 3. Lock the seed to maintain consistency across iterations. 4. Review and check for any negative prompts that may affect the desired outcome. Ensure this checklist is followed for every new generation to prevent discrepancies.

Prevent Recurrence

Parameter Combination Template

Create a parameter combination template using the format: '[PLACEHOLDER] in [STYLE REFERENCE], avoiding [UNWANTED ELEMENTS], with a locked seed for reproducibility'. Ensure that this template is detailed enough to guide the generation of consistent outputs across various scenarios. Provide examples of how to fill in the placeholders for clarity.

Frequently asked questions

Why does Nano Banana ignore my style reference?+

Nano Banana may prioritize preset styles over custom descriptors, leading to style mismatches. To fix this, try using the 'Custom' preset and explicitly describe the desired style in your prompt.

How can I ensure my subject is the focus of the image?+

If background elements are overwhelming your subject, add negative prompts that specify what to avoid. For example, use 'avoid cluttered backgrounds' in your prompt.

What should I do if faces have anatomical distortions?+

Anatomical distortions can occur due to vague prompts. Be specific about facial features in your prompt and consider using a known-working reference for better results.

How can I improve consistency across multiple generations?+

To enhance consistency, always lock the seed and use the same prompt structure. This will help maintain a stable output across different generations.

What if the generated image doesn't match my reference at all?+

If the output is far from your reference, compare it against a known-working prompt to identify discrepancies. Adjust your prompt based on what worked previously.
