Anatomy distortions in generated images can lead to unrealistic and unappealing results. This inconsistency can disrupt a creator's workflow and lead to wasted time on revisions. By following these prompts and techniques, creators can achieve more accurate anatomical representations in their images. This guide walks you through every stage of Correcting Anatomy Distortions, from Diagnose the Wall all the way through Prevent Recurrence, with a curated, copy-ready prompt at each step. Each stage targets a specific phase of the process so you always know exactly what to ask and what output to expect. Works with ChatGPT, Claude, and Gemini and any other major AI tool.
Start by identifying the root cause of the anatomical distortions in your images. This involves testing various configurations and prompts to isolate the issue.
Test Core Subject
Run a baseline test prompt using only the core subject: '[PLACEHOLDER]'. Analyze the results to determine if any anatomical issues are still present when stripped of additional descriptors or stylistic influences. Provide a detailed report on your findings, including specific examples of any errors identified.
Use Reference Prompt
Test the following known-working reference prompt: 'A realistic portrait of [PLACEHOLDER]'. Analyze the output generated by this prompt to determine if the issue lies within the wording of your specific prompt or if there are other underlying factors affecting the results.
Change Style Parameter
Change the style parameter of the current prompt to a different preset, such as 'REALISTIC' or 'ILLUSTRATIVE'. Analyze the output generated with the new style and assess whether the change affects the distortions in the nano-banana subject anatomy. Provide a comparison of the results and explain how the style influences the overall representation.
Generate Variations
Generate four variations of the prompt '[PLACEHOLDER] in a realistic style'. Ensure that each variation maintains the same anatomical features while showcasing different artistic interpretations. Analyze the consistency of these features across the generated outputs.
Compare Against Reference
Generate an image based on the prompt provided and compare it against a reference image of [PLACEHOLDER]. Identify and describe specific areas where the anatomy in your generated image diverges from the reference, providing detailed explanations for each discrepancy.
After diagnosing the issue, it's time to implement specific changes to improve anatomical accuracy.
Add Specific Descriptors
Rephrase the following prompt to include specific anatomical descriptors: "Create a detailed portrait of [PLACEHOLDER] with accurate proportions and realistic features." Ensure that the description emphasizes key anatomical elements such as muscle structure, facial features, and overall body proportions to enhance the realism of the artwork.
Use Negative Prompts
Incorporate negative prompts to improve the accuracy of anatomical representations. For example, generate a portrait of [PLACEHOLDER] while ensuring that there are no merged limbs or exaggerated features. This approach will help the AI concentrate on producing realistic anatomy.
Change Model Version
Identify the current model version being used for the nano-banana subject anatomy analysis. If a different model version is available, switch to it and evaluate whether this change improves the anatomical accuracy. Provide a summary of any differences observed in the results before and after the switch.
Restructure Prompt Order
Restructure the following prompt to place the subject first: '[PLACEHOLDER], realistic portrait style'. Explain how this adjustment can help the AI focus more on the subject's anatomy rather than the stylistic elements. Provide an example of the revised prompt.
Lock Seed Value
Lock the seed value for your AI-generated images by specifying it in your prompt. For example, use the format '[PLACEHOLDER], realistic portrait, seed [YOUR SEED]' to ensure consistent results across different generations.
Confirm that the adjustments made have successfully resolved the anatomical issues.
Generate New Variations
Generate 4 new variations of the prompt '[PLACEHOLDER], realistic portrait'. After generating the outputs, compare them to assess consistency in anatomical accuracy and note any discrepancies or improvements in detail.
Compare to Baseline
Compare the current anatomical representation of the nano-banana subject to the Stage 1 baseline prompt. Identify and list specific improvements in proportions and features, detailing how these changes enhance the overall accuracy and quality of the representation.
Test with Complex Subject
Run a complex version of the subject: 'A full-body portrait of [PLACEHOLDER] in action'. Evaluate the AI's performance in accurately depicting human anatomy, focusing on proportions, muscle definition, and movement dynamics. Provide feedback on any anatomical errors observed and suggest improvements for future iterations.
Lock Seed and Generate
Lock the seed value to ensure consistency and generate a new image using the prompt: '[PLACEHOLDER], realistic portrait, seed [YOUR SEED]'. After generating the image, evaluate whether the output maintains the expected quality and accuracy, confirming that the fix is stable across multiple generations.
Check Different Aspect Ratio
Change the aspect ratio dropdown to 16:9 and generate the image again using the prompt: '[PLACEHOLDER], realistic portrait'. Analyze the resulting image to determine if the change in aspect ratio impacts the anatomical accuracy of the subject. Provide a detailed comparison of the two images, highlighting any differences in anatomical features.
Establish reusable templates and techniques to avoid future anatomical distortions.
Base Template for Portraits
Create a reusable base template for realistic portraits in Nano Banana. The template should include the following elements: '[PLACEHOLDER], realistic portrait, accurate anatomy'. Ensure that this template is easily accessible for future projects.
Negative Prompt Template
Create a negative prompt bank that includes specific instructions to avoid common anatomical errors in character design. Include phrases such as "Avoid merged limbs," "Avoid exaggerated features," and "Avoid unrealistic proportions." Use this template to ensure anatomical integrity in future designs.
Seed-Locking Workflow
Develop a seed-locking workflow for generating images. Always specify a seed value in your prompts to ensure consistency in the output. Use the format '[PLACEHOLDER], realistic portrait, seed [YOUR SEED]' as a base for your prompts, and explain how varying the seed affects the results. Provide examples of different seed values and their impact on the generated images.
Style Consistency Checklist
Create a comprehensive style consistency checklist for the nano-banana subject anatomy. Include specific guidelines such as: 1. Use precise descriptors for anatomical features, 2. Ensure seed locking is applied consistently, and 3. Test and document variations in style. This checklist should be used for every new generation to maintain uniformity.
Reusable Prompt Structure
Create a prompt using the following structure: '[PLACEHOLDER], [STYLE], with accurate proportions, avoiding distortions'. Provide an example of how this structure can be applied to a specific subject, ensuring that the proportions are clearly defined and any potential distortions are addressed.
Distorted faces often result from the AI misinterpreting the prompt or style settings. To fix this, ensure your prompt includes specific anatomical details and use negative prompts to exclude distortions.
Improving animal anatomy requires precise descriptors in your prompt. Use terms like 'realistic proportions' and specify the animal type clearly to guide the AI.
If backgrounds are overwhelming, use negative prompts to specify 'simple background' or 'focus on [PLACEHOLDER]'. This helps the AI prioritize the subject.
To ensure consistency, always lock the seed value in your prompt. This allows you to reproduce similar results while testing for anatomical accuracy.
Yes, different style presets can influence how the AI interprets anatomy. If you're facing issues, try switching to a more realistic style or using the 'Custom' preset to describe your desired style.
