Caption undated family photographs without losing clues

Record both sides before adding a label. Include studio imprints, processing numbers and phrases written near the edge of the print.

Start with a group portrait mounted on a card bearing a photographer's stamp. Put alternative readings next to one another and give each the evidence it explains. If two records are linked by a common address or surname, look for an additional clue that belongs to the individual case. A repeated detail may be meaningful without being distinctive enough to establish the link on its own.

A documented studio address can suggest when the print was made. Keep a note of anything you expected to see but could not establish. A missing date or an uncertain location is easier to revisit when your record says which part of the object you inspected. You can then look for uncovered details instead of repeating the same search on the same material.

Use named events, a dated companion image or a known address to set the earliest and latest plausible years. Attribute each identification to its source.

A reprint may be younger than the image it carries. Write the date of observation separately from every date you infer from the object. A later reader should be able to distinguish when you read a mark from when you think it was made. This is especially useful if the record may be revised after you consult a clearer copy or a second person.

Compare the mount with a sourced photograph from the same studio. Give each individual item a location record even when several items share a title. Where a group arrives in a box or envelope, preserve what was together and how you found it. That lets you build an alphabetical or chronological index later without quietly changing evidence supplied by the earlier grouping.

List separate possible dates for exposure and printing. Reference an image by its whole item and by the region you want someone to inspect. A citation that points to a catalogue number alone can be hard to use when there are several sides or panels. Include a visual landmark in addition to an image identifier where the region does not have a printed number.

Use a short descriptive filename alongside your record number and keep the two linked. Avoid using the proposed interpretation as the only identifier. An uncertain author, place or date may change when someone sees an overlooked clue, but the connection between the item and earlier notes should remain easy to follow. Give one entry to a reader who has never handled the material. They should be able to find the source, distinguish your wording from its wording and see the reason for your conclusion. If they ask whether a detail came from the item itself or a later recollection, add that distinction where they first needed it. The furniture in a formal portrait may have belonged to the studio. Compare other prints before attributing furnishings or background props to the family. Use a distinct field for information supplied by another person, a secondary publication or a newer edition. Give it a date and an attribution. A remembered detail may be worth keeping beside the original object even when you are unable to reconcile it with what the object appears to say.

Choose three unclear photographs and prepare neutral questions before asking relatives about them. Start by keeping an untouched image or recording of the whole item. Any enlargement or contrast adjustment belongs with a working copy that identifies its source. This gives a future reader the chance to evaluate a faint character or an ambiguous detail without relying solely on the edited view.
