# Source assessment: Choosing a Natural Blur Strength

Match blur intensity to the apparent distance between the subject and the original background. Begin with the original input and record the current quality before changing any setting.

## 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 review 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.
