# How can I identify an object from a photo?

Take a clear photo that shows the object's marks, date, and the reverse side, and treat the name you get back as a guess to verify. Trove will offer an identification and a value estimate. Both can be wrong. Never eat a mushroom, or anything you foraged, because an app or a photo said it was safe.

## What to do

Photo identification is a faster first guess. It is not an expert holding the object, and it is not a lab test.

1. **Photograph the details that decide the answer.** Fill the frame. Include marks, signatures, dates, hallmarks, and the back or the bottom. A blurry photo of the pretty side is how identifiers pick the wrong cousin of the object.
2. **Read the result against the object.** If Trove, or any other tool, names something, compare that name with what you see. If a word does not match a mark on the real object, discard the result and try another photo. Do not talk yourself into the exciting answer.
3. **Separate 'what is it' from 'what is it worth'.** A likely name is not a price. Value depends on condition and on what people have paid. Sold listings and, for anything that might matter, an appraiser or a specialist dealer are the check.
4. **Stop completely if the question is 'can I eat this'.** No photo app can tell you a wild mushroom, plant, or berry is safe. The poison center's advice is the blunt version: misidentification can be fatal. Do not eat it.

## What not to do

- Do not eat a mushroom, or feed one to anyone else, based on an app.
- Do not sand, polish, or 'restore' an object before you know what it is. You can wipe out the thing that made it worth describing.
- Do not post a photo of something valuable, with your location, and expect the replies to be appraisals.

For a possible antique, a piece of jewelry, or art, use an appraiser or a specialist when the decision is whether to insure it, sell it, or repair it. For a suspected poisoning, contact a poison center or emergency services. Do not wait on an app.

## Where Trove helps

Trove is built for this first guess: a photo in, a possible identification and a value estimate out. The estimate is not an appraisal. If you subscribe, Lens Scan Pro is billed by Apple. The safety rule does not change with a subscription. A mushroom is still not food because a screen said so.

## Other ways

### A reverse image search

Useful for printed objects, posters, and products that exist in many photos. It still returns lookalikes. You have to compare.

### A specialist

A dealer, an appraiser, or a museum registrar for objects. A local expert or a mycological society for fungi, and even then you do not eat on their casual glance. For poisoning, a poison center.

## Questions

### Why did it name the wrong thing?

Lookalikes, bad light, and a missing back or mark will do it. The result is a guess. Another angle often changes the guess. Neither guess is proof.

### Can I trust it for a dog's breed or a rock?

You can use it as a hint. Mixed-breed dogs and common rocks are easy to over-call from one photo. A vet, a shelter, or a rock club can go further. The app's label is not a pedigree or a geology report.

### Is the value what I can sell it for today?

No. It is an estimate. Sold listings, and a dealer if it might be worth real money, are how you find a price someone will pay.

### What if the photo is of a mushroom?

Use it only as a reason to be more careful, never as permission to eat. If anyone has already eaten an unknown mushroom and feels ill, contact a poison center or emergency services.
