Blurry patches and halos can appear during the upscaling process, leading to unsatisfactory image quality. This distortion can disrupt a creator's workflow, making it difficult to achieve polished final outputs. By following these prompts and techniques, creators can enhance their images and maintain clarity in their work. Built across 4 distinct stages covering Diagnose the Wall, Isolate and Fix, Verify the Resolution and more, this guide gives you one expert prompt per step so you never have to write from scratch or guess what the AI needs. The prompts work in ChatGPT, Claude, and Gemini and are designed to get usable output on the first try.

Diagnose the Wall

Start by identifying the cause of the blurriness in upscaled images. Test different variables to pinpoint the issue.

Test Core Subject

Run a baseline test prompt using only the core subject: '[PLACEHOLDER]'. Analyze the output to determine if any blurriness is inherent to the subject itself or if it arises from the upscaling process. Provide a detailed explanation of your findings and any potential adjustments needed for clearer results.

Diagnose the Wall

Use Reference Prompt

Test the following reference prompt that previously generated clear images: '[PLACEHOLDER]'. Analyze the output and determine if the same issue with nano-banana upscaling artifacts persists, noting any differences in clarity or detail compared to the original images.

Diagnose the Wall

Change Style Parameter

Change the style parameter in the left panel to a different preset that is known for producing clear images. After making this change, analyze whether the blurriness in the output has been resolved and provide a comparison of the results before and after the adjustment.

Diagnose the Wall

Generate Variations

Generate four variations of the prompt '[PLACEHOLDER]'. For each variation, analyze the level of blurriness and consistency in the outputs, providing a brief explanation of any differences observed among them.

Diagnose the Wall

Compare Against Reference

Compare the generated image to the reference image or description that exemplifies clarity. Identify and describe at least three specific areas where the generated image deviates from the reference, explaining how each deviation affects the overall clarity and quality.

Diagnose the Wall

Isolate and Fix

Now that you've diagnosed the issue, implement specific techniques to fix the blurriness.

Adjust Style Preset

Select a style preset that emphasizes clarity and detail for the nano-banana upscaling artifacts. If the available presets do not meet your needs, describe the specific characteristics of the desired style, including elements such as color saturation, sharpness, and texture, to guide the adjustment process effectively.

Isolate and Fix

Rephrase Prompt Descriptors

Rephrase the following prompt to enhance clarity and specificity: '[PLACEHOLDER]'. Ensure to include descriptors such as 'high detail', 'sharp focus', and 'crisp edges' to convey the desired visual quality effectively. Provide at least three variations that incorporate these elements.

Isolate and Fix

Add Negative Prompts

Incorporate negative prompt elements to discourage blurriness in your generated images. Specifically, modify your prompt to include terms such as 'no blur' and 'no halos' by formatting it as follows: '[PLACEHOLDER], no blur, no halos'. Provide examples of how this adjustment improves the final output quality.

Isolate and Fix

Change Model Version

Switch to a different model version in the settings to improve the handling of upscaling artifacts in nano-banana images. Identify the available model versions and evaluate their performance in reducing artifacts, then implement the change and assess the results.

Isolate and Fix

Restructure Prompt Order

Restructure the prompt by placing the subject first and the style last. For example, format it as '[SUBJECT] in [STYLE]'. Explain how this change can help the AI prioritize the subject more effectively and provide an example of a prompt that follows this structure.

Isolate and Fix

Verify the Resolution

Confirm that the adjustments made have resolved the blurriness issue.

Generate New Variations

Generate 4 new variations of the image using the adjusted prompt: '[PLACEHOLDER], high detail, sharp focus'. After generating these variations, compare each output to the previous baseline image in terms of clarity, detail, and overall quality. Provide a summary of the differences observed.

Verify the Resolution

Compare Against Baseline

Compare the new output for the nano-banana upscaling against the Stage 1 baseline. Analyze the differences in blurriness and detail, and provide a summary of whether the blurriness has been reduced or eliminated, including specific examples from both outputs.

Verify the Resolution

Test Harder Subject

Run a test using a more complex subject that typically generates blurriness. Use the prompt: '[PLACEHOLDER] with intricate details' and analyze the results for any upscaling artifacts. Provide a detailed comparison of the output quality against simpler subjects and suggest improvements based on your observations.

Verify the Resolution

Lock Seed for Consistency

Lock the seed value in the settings to maintain consistency in image generation. Then, generate a new image using the adjusted prompt: [ADJUSTED PROMPT]. Describe any changes in the output compared to previous images and evaluate the consistency of the results.

Verify the Resolution

Check Different Aspect Ratios

Check the output generated by the prompt at various aspect ratios using the aspect ratio dropdown. Analyze how each aspect ratio influences the clarity and quality of the resulting image, and provide a detailed comparison of the differences observed.

Verify the Resolution

Prevent Recurrence

Create reusable templates and techniques to avoid similar issues in the future.

Base Template for Clarity

Create a reusable base template for clarity in Nano Banana. The template should include the following elements: '[PLACEHOLDER], high detail, sharp focus, no blur'. Ensure that this template can be easily modified by changing only the subject while maintaining the specified attributes.

Prevent Recurrence

Negative Prompt Bank

Create a negative prompt bank that includes phrases such as 'no blur', 'no halos', and 'no distortion'. Provide at least ten additional phrases that can help maintain clarity in generated images, and explain how each phrase contributes to reducing specific artifacts in the output.

Prevent Recurrence

Seed-Locking Workflow

Establish a workflow for generating images that includes a mandatory step to lock the seed. Explain the importance of this practice in maintaining consistency across similar prompts and provide a detailed outline of the steps involved in implementing this workflow effectively.

Prevent Recurrence

Style-Consistency Checklist

Create a comprehensive checklist for ensuring style consistency in nano-banana upscaling. Include steps for verifying the selected style preset, confirming the inclusion of clarity descriptors, and assessing overall visual coherence. Provide specific criteria for each step to facilitate thorough evaluation.

Prevent Recurrence

Parameter Combination Template

Save the following parameter combination template for future reference: '[PLACEHOLDER], [STYLE], high detail, no blur'. Explain how each component of this template contributes to reducing upscaling artifacts in nano-banana images, and provide examples of when to adjust each parameter for optimal results.

Prevent Recurrence

Frequently asked questions

Why do my images have blurry patches after upscaling?+

Blurry patches can occur due to the upscaling algorithm not properly handling fine details. To fix this, ensure you use a style preset that emphasizes clarity and add negative prompts to discourage blurriness.

How can I avoid halos around subjects?+

Halos can appear when the background and subject contrast sharply. Use negative prompts like 'no halos' and adjust the style preset to one that minimizes this effect.

What should I do if the background overwhelms the subject?+

If the background is too busy, try rephrasing your prompt to emphasize the subject first. Use descriptors like 'focus on [PLACEHOLDER]' to guide the AI.

Why do faces look distorted in my images?+

Distorted faces may result from the selected style preset not being suitable for portraits. Test with different style presets and adjust your prompt to prioritize facial details.

How do I ensure consistent quality across generations?+

To maintain consistent quality, always lock the seed and use a base template that includes clarity descriptors. This helps the AI generate similar outputs.
