According to The Verge, the feature, called Reference Image, will arrive with the iPhone 18 Pro and Pro Max later this month. TechCrunch reports that Apple is presenting it as a way to help determine whether photos have been edited, including through AI.## How the feature is supposed to work- In Reference mode, the camera captures signed sensor data using the phone’s new camera sensor.- Apple says Private Cloud Compute turns that signed data into an “unalterable reference image.”- The reference image can be viewed in the Photos app, where users can compare it with other versions of the same photo. The intended use is to make post-capture changes easier to spot.## What the evidence does—and does not—showThe supplied reports describe a comparison tool, not a complete guarantee that a photo is untouched. A difference between the reference image and another copy may indicate that the image changed, but the reports do not say that the feature can identify every kind of alteration or determine which tool or method was used. Apple’s “unalterable” description is also a company claim; the supplied evidence includes no independent technical testing. The reports also do not explain how the feature will handle edits made outside Apple’s ecosystem, or whether reference images will retain the same verification properties when shared.## Why it mattersFor people who share photos in messages, social media, or work contexts, Reference Image could provide a practical way to check whether a received image differs from the version captured by the phone. It addresses a specific problem: users often cannot tell from a finished image alone whether it has been modified. The feature may make that question easier to investigate, but it does not, based on the supplied evidence, settle broader questions about a photo’s origin, context, or every possible edit.Both source reports were published on Sept. 9, 2026.## Sources- TechCrunch, “Apple has a new way to prove your iPhone photos aren’t AI slop,” Sept. 9, 2026- The Verge, “Apple’s new iPhone camera mode promises to prove your photo isn’t AI,” Sept. 9, 2026
