20 of the best prompts for fixing upscaling artifacts in images, step by step across 4 stages. Works with ChatGPT, Claude, and Gemini.
Upscaling in Midjourney can lead to blurry patches, halos, or edge distortions that detract from the original image quality. This inconsistency can disrupt a creator's workflow, making it difficult to produce polished final images. By following these prompts and techniques, creators can achieve clearer, more consistent results in their upscaled images. 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.
Start by isolating the core elements of your prompt to identify what causes the upscaling artifacts. Testing different variables will help pinpoint the issue.
Test Core Subject
Run a baseline test prompt using only the core subject: '[YOUR SUBJECT]'. Analyze the output for any artifacts that appear, and determine if these artifacts are related to the complexity of the original prompt or if they are inherent to the subject itself.
Use Reference Prompt
Test the following reference prompt: '[YOUR SUBJECT], [STYLE REFERENCE], [LIGHTING TYPE]'. Analyze the output generated from this prompt and compare it to your original results to determine if the issue persists or if it improves with this simpler and more established prompt.
Change Model Version
Change the model version for your prompt by appending either '--v 5' or '--v 6' at the end. Analyze the resulting image to determine if the artifacts present are specific to the model version used. Provide a comparison of the images generated with each version and note any differences in quality or artifacts.
Generate Variations
Generate four variations based on the prompt '[YOUR SUBJECT], [STYLE REFERENCE]'. Ensure that each variation maintains the core elements of the original prompt while introducing subtle differences to analyze the consistency of artifacts in the outputs.
Compare Against Reference
Generate an image using the prompt provided and compare it to the reference image. Identify specific areas where artifacts appear, detailing the nature of each artifact and how it differs from the reference image.
Once you've diagnosed the issue, apply specific techniques to eliminate the upscaling artifacts. Adjusting parameters and rephrasing prompts can lead to clearer images.
Add Negative Prompts
Identify the unwanted artifacts in your Midjourney output, such as blur or halo effects. Then, revise your prompt to include negative prompts by adding '--no blur --no halo' to instruct Midjourney to avoid generating these specific artifacts in future images.
Rephrase Prompt Descriptor
Rephrase the following prompt to enhance clarity and detail: '[YOUR SUBJECT], high detail, sharp focus'. Explain how each element contributes to improving the overall output quality and suggest any additional descriptors that could further enhance the prompt.
Change Style Setting
Change the style setting for your Midjourney prompt by adding '--style raw' to disable aesthetic processing. Explain how this adjustment can help maintain the integrity of the original image during the upscaling process, and provide examples of when this might be beneficial.
Adjust Prompt Order
Restructure the following prompt by placing the subject first: '[YOUR SUBJECT], [STYLE REFERENCE], [LIGHTING TYPE]'. Explain how this adjustment can enhance clarity in the generated output and provide an example of a revised prompt using this structure.
Lock the Seed
Lock the generation seed in your Midjourney prompt by adding '--seed [YOUR SEED]'. Explain how this helps maintain consistency across iterations and aids in determining whether the artifacts are random or a result of other factors. Provide examples of how to adjust the seed value for different outcomes.
After implementing fixes, run tests to confirm that the upscaling artifacts have been resolved. Comparing outputs will help validate your adjustments.
Generate New Variations
Generate 4 new variations of the image based on the adjusted prompt: '[YOUR SUBJECT], [STYLE REFERENCE]'. After generating these variations, compare the outputs to determine if the upscaling artifacts have been resolved and provide a summary of your findings.
Compare to Baseline
Compare the current image to the baseline image from Stage 1. Identify any remaining artifacts and evaluate whether the adjustments made have effectively improved the image quality. Provide a detailed analysis of the differences observed and suggest further actions if necessary.
Test with Complex Subject
Test the upscaling capabilities of Midjourney by using a more complex version of your subject: '[COMPLEX SUBJECT], [STYLE REFERENCE]'. Analyze the output for any artifacts or issues that arise at this higher resolution and provide a detailed assessment of the results.
Check Different Aspect Ratio
Check the output image for artifacts after running the prompt with the aspect ratio set to 16:9 by adding '--ar 16:9'. Analyze the differences in quality and detail compared to the original dimensions, and determine if any artifacts are present due to the change in aspect ratio.
Lock Seed and Test Again
Generate a new image using the same prompt while ensuring the seed is locked. After generating the image, analyze it to determine whether the artifacts present are consistent with the previous image or if they appear to be random. Provide a detailed comparison of the artifacts observed in both images.
Create reusable templates and workflows to prevent future issues with upscaling artifacts. These will streamline your process and enhance consistency.
Base Prompt Template
Create a high-quality upscaling prompt using the following template: '[YOUR SUBJECT], high detail, sharp focus, --no blur --no halo'. Ensure that the subject is clearly defined and consider any specific characteristics or elements you want to emphasize in the image.
Negative Prompt Bank
Create a negative prompt bank that includes the following terms: '--no blur', '--no halo', and '--no distortion'. Explain how to effectively incorporate these terms into your prompts to minimize artifacts in generated images.
Seed-Locking Workflow
Establish a workflow for generating images in Midjourney by always locking the seed using the '--seed [YOUR SEED]' parameter for every new prompt. Explain how this practice helps maintain consistency across different generations of images and provide examples of scenarios where seed locking has improved the output quality.
Style-Consistency Checklist
Create a style consistency checklist for generating images in Midjourney. Include specific steps such as using the same style reference for each image, locking the seed to maintain consistency, and incorporating negative prompts to avoid unwanted elements. Ensure the checklist is clear and actionable for every new image created.
Parameter Combination Template
Create a parameter combination template for Midjourney that includes the following elements: [YOUR SUBJECT], [STYLE REFERENCE], --style raw, --no blur, and --no halo. Explain how this template can be adapted for different artistic styles and subjects to prevent common upscaling artifacts.
Blurry patches often occur due to the way Midjourney processes images during upscaling. To fix this, use negative prompts like '--no blur' and ensure your prompt emphasizes clarity.
Halos can appear when the AI misinterprets edges during upscaling. Adding '--no halo' to your prompt can help prevent this issue.
Edge distortion is typically a result of the AI's interpretation of complex details. Simplifying your prompt and using clear descriptors can help mitigate this.
Locking the seed with '--seed [YOUR SEED]' ensures that your images maintain consistency across generations. This helps reduce random variations.
To confirm your adjustments, compare new outputs against your baseline images. Look for improvements in clarity and the absence of artifacts.
