Reuse preparation: Writing Useful Alt Text from an Image

Describe the information the image contributes instead of listing every visible object. Save the input assumptions, chosen settings, output version, and any remaining uncertainty.

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.
