A sample caption separates visible detail, documented context and unanswered questions.
Describe the image plainly
Start with a concrete description of what is visible. Avoid supplying a name, place or date that has not been verified. A short caption can still be informative.
Add context with a source
When reliable contextual information is available, identify where it comes from. Do not let the tone of the sentence imply more certainty than the evidence supports.
Read the caption without the image
Check whether someone could mistake an illustration for a record of a real event. In a demonstration site, state clearly when a photograph is illustrative or an article is sample content.
Try the idea in your own setting
This is an original demonstration editorial, written to show how an article can combine a clear introduction, practical questions and a measured conclusion. Adapt the exercise to your own circumstances. Keep a brief note about what you changed, what you observed and what you would check before drawing a wider conclusion. The illustrative photograph is not documentation of the scene described here.
