How to Record a Photographer's Studio Mark
By ImgHeal · Updated
Preserve imprints, addresses, and logos that can help place an old portrait in time and location.
Gather evidence before editing
Capture the full mount, front, back, embossed mark, and printed address before making a portrait crop. Use angled light for a blind stamp without rubbing chalk or powder into it.
Record the research clearly
Transcribe the mark exactly, including spelling and punctuation, then record where it appears. Search catalogs, directories, or archive collections separately and keep links with the photo record.
Keep conclusions separate from guesses
Treat an operating date as a range, not proof that the portrait was made on one exact day. Retain the studio mark in the master even when a display crop omits it.
Check before you finish
- Capture marks with the full mount.
- Transcribe exactly.
- Use studio dates as a range.
