# Output inspection: Preparing Photos Before Blur

Use a clear source image with enough resolution for reliable subject-boundary detection. 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 ensure high quality when blurring photo backgrounds, use high resolution source images and verify the results at the intended display size. Follow a consistent review sequence that includes comparing the final output against the original to identify hidden details.

## Themes
- Photo quality control
- Image processing workflow
- Blur preparation techniques

## Key takeaways
- High resolution source images are necessary for accurate subject boundary detection.
- The recommended workflow involves preserving the original input before applying changes.
- Changes should be kept to the minimum necessary to complete the specific task.
- Final results must be compared against the source at the intended display size.

## Insights
- Previews often obscure critical details that only become visible at the final intended display size.
- Effective quality control requires maintaining a record of settings and uncertainty for future reproducibility.

## Open questions / gaps
- What specific criteria define a reliable subject boundary detection?
- How should uncertainty be quantified or recorded during the processing sequence?
