# Output inspection: Avoiding Halos Around a Subject

A bright or dark fringe usually means the subject mask needs closer edge inspection. Review the result at its intended size and inspect details that previews can hide.

## Practical review sequence

1. Preserve the original input and note its important limitations.
2. Apply the smallest change that addresses the current task.
3. Compare the result with the source at the intended display size.
4. Record settings and uncertainty before the result is reused.

This public workflow document covers one bounded quality-control task. It is intended as a repeatable reference rather than a substitute for checking the source material and the final output directly.

## Summary
To avoid halos around a subject, inspect the mask at the intended display size rather than relying on previews. Follow a systematic review sequence to ensure quality control while preserving the original input.

## Themes
- Image quality control
- Subject masking techniques
- Workflow best practices

## Key takeaways
- A bright or dark fringe around a subject indicates that the mask requires closer edge inspection.
- The practical review sequence requires comparing the result to the source at the final display size.
- The workflow emphasizes preserving the original input and noting its limitations.
- This document serves as a repeatable reference rather than a replacement for direct source and output inspection.

## Insights
- Previews often obscure edge artifacts that become visible at the intended final display size.
- Quality control should prioritize minimal intervention rather than aggressive editing.
- Documentation of settings and uncertainty is a necessary step before reusing output.

## Open questions / gaps
- What specific tools or methods are recommended for correcting the identified edge fringes?
