How to Photograph an Autograph for Identification
Prepared by Lingga Kusuma Sakti for Autograph Identifier AI. This guide is for research and is not professional authentication or an appraisal.
A useful autograph photo shows both the complete signature and the object around it. Keep the original files so a reviewer can inspect what the camera actually captured.
Start with an overview
Photograph the complete item, including labels, inscriptions, and obvious condition issues. For a framed object, document the frame and any visible labels without taking the item apart.
Take a sharp close-up
- Use soft, even light and move the light source to reduce glare.
- Hold the camera steady and keep the entire signature in focus.
- Include a little of the surrounding surface for context.
- Check the photo at full size before putting the item away.
Adjust for the object
Baseballs: take separate photos of each curved panel and the printed markings. Cards and photographs: capture the front and back where possible. Jerseys: include the signed area and any visible identifiers, keeping fabric relaxed rather than stretching it.
Preserve an honest record
Avoid filters, tracing, generative restoration, and heavy sharpening: they can obscure or invent strokes. Save unedited originals and keep edited copies separate. Don't include private addresses or unrelated sensitive documents in images you share.
What a photo cannot prove
A photograph can help generate research leads, but cannot establish the full provenance or guarantee authenticity. Record where the item came from and compare multiple documented examples. For a valuable item, consult an appropriate professional.
