How do I caption a photo with who, what, where, and when?

Use a repeatable caption pattern

A dependable format is: who, doing what, where, when. For example: “Asha and Daniel opening gifts at the kitchen table in Portland, December 2019.” Add one detail that explains why the moment matters if it is not visible, such as a reunion, first day of school, or a relative visiting from out of town. This is enough for most family photos. A caption does not need to list every person or object; its job is to preserve the context most likely to be forgotten.

Separate caption text from search labels

Use a sentence-like caption for the story of the image and keywords for repeated search terms. Captions are a good place for relationships, small anecdotes, and context such as “after the parade.” Keywords work better for names, places, and event categories that you want to filter across many photos. If your app has a description field, put the full caption there rather than embedding it in the filename. Keep filenames short and stable so that they remain manageable outside the app.

Work from reliable context

Caption a group of photos while the event is still fresh, using the calendar, invitations, or conversation with family members to confirm details. If you are working on older material, begin with the images that have the clearest context and use those captions to guide related photos. Read captions back a few weeks later: can you identify the people and occasion without relying on memory? Improve only the entries that remain confusing. A short, accurate caption is more useful than a lengthy story with uncertain details. Focus first on images likely to be shared, printed, or revisited by family members.

Before making disruptive changes

• Do not overwrite an existing description in a batch operation without checking whether it contains family notes you want to retain.
• Mark uncertain details as approximate or unknown instead of turning a guess into a definite caption.
