The iPhone 18 Pro models support Apple Reference Image, a way to verify that a photo was taken with an iPhone and hasn't been edited. Apple says it's a method to prove that something actually happened and wasn't AI-generated, likening the feature to a digital film negative. Apple Reference Image offers a trustworthy, scalable guarantee that a reference image is what it claims to be: a real photograph, captured by a real sensor in an iPhone camera, at a specific time. It sets a new standard for verifiable digital photography. Apple introduced Apple Reference Image when debuting the ‌iPhone 18 Pro‌ and Pro Max, and today the company shared more information on how the feature works on its Security Research blog . Apple Reference Image boots the camera sensor into a specialized reference mode. The mode instructs the sensor to cryptographically sign pixel data immediately after capture, and the sensor firmware is prevented from modifying the data. Other authentication systems don't sign images until the end of the software processing pipeline, which Apple says leaves images vulnerable to tampering attacks. Apple Reference Image creates a "secure digital negative" protected from software compromise alongside a standard editable photo. The negative is stored on-device and includes pixel data, sensor metadata, and cryptographic timestamps with lower and upper bounds. When a user decides to "develop" the negative for verification, it is sent unprocessed to Private Cloud Compute. Private Cloud Compute runs the steps needed to render the image in a secure, private, and verifiable environment. Apple says the feature resists data injection attacks, compromised operating systems, hardware attacks, and cryptographic attacks. Apple believes Apple Reference Image is the only image provenance system with quantum-secure defenses. In case the system is breached, there is a revocation option. Private Cloud Compute calculates a confidence score for each image, and Apple can revoke individual photos or an entire sensor if fraud is detected. To safeguard photographers, Apple Reference Image avoids using an explicit, public credential for photographers, and it prevents public association between different photos taken by the same sensor. The confidentiality of the image is protected, including from Apple. Apple Reference Image is opt-in and is limited to the Main camera sensor. More information on the ins and outs of Apple Reference Image can be found in Apple's full blog post .

To take advantage of the iPhone Duo 's dual-display design, Apple is introducing new Camera app features that are unique to the foldable iPhone. Smart Take Smart Take uses AI to determine when everyone (including the iPhone owner) is ready for a group shot, so no one has to use a timer or stay out of the picture to capture the image. You can prop up the ‌iPhone Duo‌ in a half-folded orientation, get in frame, and then wait for the group shot to be taken. Kid Cue Kid Cue shows little Peanuts animations to children so they look at the camera when you're taking a photo. Duo Preview With Duo Preview, the Camera app shows a live preview of the shot on both displays, so the subject you're taking a photo of can make adjustments. Duo FaceTime Nearby friends can participate in a FaceTime call using the outer display while the iPhone owner uses the inner display, so nobody has to crowd around the iPhone or pass it around to get on video. Duo ‌FaceTime‌ is not the same as Dual Capture, which records video with both the front and rear cameras. Duo ‌FaceTime‌ specifically uses the outer display to allow another person to join in on a call. Unique Form Factor Features The ‌iPhone Duo‌ can be used in multiple orientations, including when it's half-folded. The Duo stands up on its own, for taking ‌FaceTime‌ calls and recording video without holding it. The folding mechanism acts like a built-in tripod and stand, so it's also useful for selfies and long exposures. You can also capture selfies with the higher-quality 48MP rear camera while using the outer display as a viewfinder, which isn't something you can do with a slab iPhone. Camera Hardware The ‌iPhone Duo‌ has a "Dual Fusion" two-camera setup with a 48MP Main camera. It's basically the same camera that's in the iPhone 17 (not the 17 Pro), offering 26mm 24MP images by default, along with 12MP 2x "telephoto" images at 52mm. The camera supports sensor-shift optical image stabilization, but not the second-generation version available in the Pro models. It also does not support spatial photos or the ProRAW format. It also includes a 48MP Ultra Wide camera with a 13mm focal length and macro capabilities. Since there's no Telephoto lens, the ‌iPhone Duo‌ is limited to 2x optical-quality zoom in, 2x optical zoom out, and digital zoom up to 10x for images. Other Camera Capabilities Like the iPhone 18 Pro and Pro Max, the ‌iPhone Duo‌ supports the latest Photographic Styles, which adds texture and grain parameters. Video Smart focus tracking is a feature new to the ‌iPhone Duo‌ and the ‌iPhone 18 Pro‌ models. It uses AI to keep a subject in focus at all times, and pick up subject tracking if the subject exits the frame and then reappears. The Duo supports 4K Dolby Vision video recording at up to 120 fps, and Cinematic mode for recording videos in 4K Dolby Vision at up to 60 fps. For the first time, Cinematic mode effects can be added to a video after capture on the Duo and ‌iPhone 18 Pro‌. Apple also says there's improved low-light video on the Duo when recording at 1080p. Time-lapse video recording with stabilization up to 4K Dolby Vision is a new ‌iPhone 18 Pro‌ and ‌iPhone Duo‌ option. It's especially useful on the ‌iPhone Duo‌ because you can record a stable video without the need for a tripod. Front Camera The ‌iPhone Duo‌'s outer front-facing camera is 12MP, not 18MP like the ‌iPhone 17‌ and ‌iPhone 18 Pro‌ models. It otherwise has the same features. The inner display has a 1080p ‌FaceTime‌ camera that's under the display. Missing Camera Features Compared to the ‌iPhone 18 Pro‌ and Pro Max, the ‌iPhone Duo‌ has a more rudimentary camera system. It lacks many features available on the Pro models. Telephoto lens Pro Controls Apple Reference Image Variable aperture Second-generation sensor-shift optical image stabilization Adaptive True Tone flash Spatial photos and video recording ProRAW ProRes ProRes RAW Genlock Apple Log 2 video recording Studio-quality four-mic array Launch Date The ‌iPhone Duo‌ will be available for pre-order on October 16, and it will launch on October 23. Pricing starts at $1,999.
