The quality of your photos directly affects the accuracy of your analysis. Follow these guidelines to get the best results.
General Best Practices
- Use natural daylight or diffused artificial light. Avoid harsh shadows and flash — they obscure surface details and distort colors.
- Photograph from multiple angles: front, back, top, bottom, and both sides. More views give the AI more information.
- Include a common object for scale — a coin, ruler, or standard playing card placed next to the item.
- Use a plain, neutral background (white or light gray). Busy backgrounds make it harder for the AI to isolate the object.
- Ensure sharp focus, especially on detail shots. Blurry photos are the single biggest cause of 'Uncertain' verdicts.
Ceramics & Porcelain
- Photograph the bottom/base clearly — maker's marks, kiln stamps, and reign marks are critical for dating and attribution.
- Capture glaze details: crackle patterns, color variations, and any iridescence. A close-up of the glaze surface tells the AI about firing technique and age.
- Document any chips, hairline cracks, or repairs. Zoom in on damaged areas. Condition significantly affects value.
Paintings & Prints
- Photograph the signature or monogram with a close-up. If unsigned, note that in your description.
- Always photograph the back of the canvas or panel. Labels, gallery stamps, auction stickers, and stretcher bar marks provide provenance clues.
- For oil paintings, capture brush stroke detail with raking light (light from the side). This reveals technique and helps distinguish originals from reproductions.
- Include the frame — it can be independently valuable and provides dating context. Photograph any marks or labels on the frame.
Jewelry & Watches
- Photograph all hallmarks, purity stamps, and maker's marks. Use macro mode or a magnifying lens if available.
- Show clasps, pin mechanisms, and settings — construction methods help date the piece.
- For gemstones, capture them with and without flash. Note the stone color in natural light in your description.
- Mention weight in your text description if you can weigh the piece (kitchen scale works). The AI cannot assess weight from photos alone.
Furniture
- Photograph joinery close-ups: dovetails, mortise-and-tenon joints, pegged construction. These are the strongest indicators of age and origin.
- Capture all hardware (hinges, pulls, locks) — original vs. replaced hardware significantly affects value.
- Show the wood grain in good light. Include both finished and unfinished surfaces (drawer bottoms, backs).
- Look for maker's stamps, paper labels, branded marks, or stenciled numbers — often found on drawer bottoms or back panels.
Bronzes & Metalwork
- Photograph the patina in detail — color, texture, and distribution. Natural vs. artificial patina is a key authenticity indicator.
- Always photograph the base/bottom. Foundry marks, edition numbers, and casting evidence are usually here.
- Capture any inscriptions, signatures, or foundry stamps with a close-up.
Other Categories
For items not covered above, follow the general best practices and pay special attention to: any maker's marks, labels, stamps, or inscriptions; material details visible in close-ups; construction methods; and any text or numbers on the item. Mention material, approximate weight, and dimensions in your description field.
