AI Cataloging for Fine Art
Fine art cataloging demands precise attribution language that most auctioneers never learned. The difference between 'by,' 'attributed to,' 'circle of,' and 'manner of' carries real legal weight. Gavelist applies standard auction house attribution hierarchy automatically, identifies media types and signatures from photos, and generates descriptions that stand up to scrutiny from collectors and dealers.

Why Fine Art Cataloging Is Challenging
- Attribution levels must follow industry convention — 'by' implies certainty, 'attributed to' implies probable, 'manner of' implies stylistic similarity only
- Signatures can be forged, added later, or partially obscured — descriptions must note what is visible without authenticating
- Distinguishing original oils from giclees, lithographs, or hand-embellished prints requires close inspection of surface texture
- Frame condition and period affect value independently from the artwork itself
- Provenance documentation found with the piece should be noted but cannot be verified from photos
What Gavelist Identifies from Photos
- Media identification — oil on canvas, watercolor on paper, acrylic, pastel, mixed media
- Signature presence, location, and legibility with proper hedging
- Print types — lithograph, serigraph, etching, giclée — with edition numbering when visible
- Subject classification — landscape, portrait, still life, abstract, figurative
- Frame description — period-appropriate, later addition, gilt, carved wood
- Condition indicators visible in photos — craquelure, foxing, canvas sag, frame damage

Photography Tips for Better AI Results
- 1Photograph the signature separately with good lighting — this is the single most important detail shot
- 2Capture the back of the canvas for gallery labels, stretcher bar marks, and provenance stickers
- 3Shoot in natural light without flash to avoid glare on varnished surfaces
- 4Include a frame shot and a close-up of surface texture to help distinguish prints from originals

Frequently Asked Questions
Does Gavelist authenticate artwork or provide valuations?
No. Gavelist follows standard auction house attribution hierarchy — using terms like 'attributed to,' 'circle of,' or 'manner of' based on what is visually observable. Authentication and valuation require in-person expert examination. The AI generates legally appropriate descriptions, not certificates of authenticity.
How does Gavelist distinguish original paintings from prints?
When you provide close-up surface texture photos, Gavelist identifies indicators like canvas weave, brushstroke impasto, dot patterns (giclée/lithograph), and plate marks (etchings). The combination of surface texture and edge examination allows accurate media classification in most cases.
Should I photograph the back of framed artwork?
Absolutely. The back of artwork often contains gallery labels, auction house stickers, stretcher bar marks, and provenance information that dramatically improve the AI description. A front photo alone misses half the identification potential.
