Painting signature identification: build a useful photo record
For painting signature identification, pair a close-up of the signature with a photograph of the full work. Record uncertain letters instead of guessing an artist, and keep accessible labels or inscriptions with the same research file.
Which photographs should I take of a painting?
Photograph the entire front straight on, then the signature and any visible labels. Record the dimensions and whether they include the frame. Photograph the back only if it is safely accessible; do not remove a sealed backing or detach the work for this checklist.
What if I cannot read the signature?
Write down the characters you can see and leave a question mark for uncertain ones. Try another light angle before changing the image. Save an unedited original so sharpening or contrast adjustments do not become the only record of a letter shape.
Does a matching signature establish the artist?
No. Use a possible signature match to find documented references and ask better questions. Keep the subject, medium description, dimensions and ownership information available for a specialist. CuriSnap does not currently provide artist authentication.
