# Output inspection: Writing Useful Alt Text from an Image

Describe the information the image contributes instead of listing every visible object. 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
Effective alt text should focus on the information an image contributes rather than listing every visible object. Review the final result at its intended display size to ensure all necessary details are captured.

## Themes
- Alt text best practices
- Image description workflow
- Quality control process

## Key takeaways
- Alt text should focus on the information an image contributes rather than listing every visible object.
- The review sequence requires comparing the final result against the source at the intended display size.
- Settings and uncertainty should be recorded before an output is reused.
- This workflow is a repeatable reference and not a substitute for direct source material verification.

## Insights
- Effective alt text prioritizes the informational contribution of an image over a literal inventory of its contents.
- Preview images often obscure critical details that must be verified at the intended final display size.
- Documentation of uncertainty is a formal step in the quality control process.

## Open questions / gaps
- What specific criteria define an important limitation of an input image?
- How should one document uncertainty in a way that is actionable for future users?
