A few simple techniques can dramatically improve AI identification accuracy. Here's how to capture the perfect scan.

The 3-photo system

Three strategic photos give our AI complete information about your item.

Example photo for Full View
01

Full View

Capture the entire item in a single shot. Include any visible labels, stamps, or maker's marks. This gives the AI the overall shape, style, and proportions.

  • Show the complete item
  • Include any attached labels
  • Capture distinctive silhouette
Example photo for Details & Marks
02

Details & Marks

Zoom in on signatures, stamps, hallmarks, labels, or engravings. These are often the key to identification and authenticity.

  • Maker's marks and signatures
  • Patent numbers or dates
  • Labels and stickers
Example photo for Close-up Texture
03

Close-up Texture

Show the surface texture, patina, grain, or unique wear patterns. This helps determine age, material, and authenticity.

  • Surface texture and patina
  • Wood grain or material details
  • Signs of age or wear

6 essential tips

Follow these fundamentals to give our AI the best possible images to work with.

Use Natural Light

Photograph near a window. Daylight reveals true colors and details the AI uses for identification.

Clean Background

Use a plain surface (white paper, wood table). Cluttered backgrounds confuse the AI.

Capture 3 Angles

Full view, maker's marks, and texture close-up give the AI complete information.

Sharp Focus

Tap to focus on the item. Blurry photos miss critical details like text and patterns.

Show Scale

Include a coin or ruler for size reference when relevant (helpful for coins, figurines).

Add Context

Share what you know: origin, age, maker. Even partial info dramatically improves accuracy.

Do vs don't

Common photography mistakes and how to avoid them.

Lighting
Natural daylight near a window
Harsh flash creating glare spots
Background
Plain neutral background
Cluttered table with other objects
Focus
Sharp, in-focus image
Blurry or motion-blurred photo
Coverage
Multiple angles (3 photos)
Single distant shot
Framing
Item fills most of the frame
Tiny item with lots of empty space
Shadows
Even, diffused lighting
Dark shadows on one side

Add context for better results

Photos are great, but adding what you know about the item can dramatically improve accuracy. Context like period and origin is especially valuable for authenticity analysis.

All context fields are optional. Even uncertain guesses help narrow down identification. The AI weighs your input alongside visual analysis.

Artist / Maker / BrandHigh impact

Knowing the maker helps verify authenticity and dramatically narrows identification possibilities.

Origin / LanguageHigh impact

Critical for printed items like cards, books, and documents. Helps identify regional variations.

Time PeriodMedium impact

Helps narrow down styles, manufacturing methods, and materials used in different eras.

Condition NotesMedium impact

Affects value estimation significantly. Note any damage, repairs, or restoration.

Additional NotesVariable impact

Provenance, family history, or purchase location can provide crucial identification clues.

Provenance details improve gap detection accuracy

Common questions

How many photos should I take?

We recommend 3 photos: a full view, a close-up of any marks or signatures, and a texture/detail shot. This gives our AI the best chance of accurate identification.

Does the background really matter?

Yes! A cluttered background can confuse the AI into identifying wrong objects. A plain, neutral surface (white paper, wood table) helps the AI focus on your item.

Why is natural light so important?

Natural daylight reveals true colors and surface details that flash photography can wash out. It helps the AI accurately assess materials, patina, and age.

What if I don't know anything about the item?

That's perfectly fine! The AI can work with just photos. However, any context you can provide, even uncertain guesses, helps narrow down the possibilities.
