Track printed photographs and their negatives

Use a light source suitable for viewing negatives. Compare crops, relative positions and small background shapes with candidate prints.

Pair a small print with a negative showing an extra lamppost along its outer margin. 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.

Repeated background detail can confirm the association despite the crop. The most helpful comparison preserves order. Use the source order for transcriptions and marks, and create a separate chronological or alphabetical view when it helps the reader. This lets you search a useful index while returning to the original arrangement if the relationship between adjacent items becomes important.

Keep a catalogue entry for each object and point each record to the other. Record the physical envelope and strip position for the negative.

Several family photographs from one afternoon may differ by only one movement. Tie each observation to a place in the source, such as a page, side, timecode or corner of a frame. A record that says where a detail was found is useful even when the immediate interpretation changes. It also saves the next reader from starting the search again at the first page.

Compare hands and small shadows before linking the two. Finish with enough information to find the source and understand what you did to it. Include the identifier, location, date of inspection and the state of unfinished work. If the material could be shared more broadly later, keep a place for permission and credit information alongside its public description.

Note why an uncropped reference print might be helpful in future research. 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.

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. Record which way the negative is oriented when read by its edge numbers. Reversals can make handwriting or uniform buttons appear on the wrong side. 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.

Use one shared caption for the image and preserve condition notes separately for its two physical forms. 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.
