Apple announces a new iPhone feature called “Apple Reference Image” that aims to authenticate images by showing whether a photo has been altered, including edits made with AI tools. Apple says the feature can provide a way to prove what the camera captured rather than relying only on what appears in the final file.
Reports describe the feature as opt-in and tied to the iPhone 18 Pro, where taking a photo in Reference mode records signed camera information that can later be shown alongside the main image. The Photos app presents a comparison view—described as a “digital negative” or reference image—so viewers can compare the reference data with the displayed photo to spot differences.
Outlets generally agree on the goal: improving image provenance amid increasingly convincing synthetic and edited imagery. Some sources focus on the user-facing comparison in the Photos app, while others emphasize the underlying process, including signed sensor data and involvement of Apple’s private cloud compute. Apple also indicates the feature is intended for photojournalists, photographers, and everyday viewers, and that Apple plans to open related APIs for third-party apps in future operating system versions.
