It\u2019s basically impossible<\/a> nowadays to tell if a photo was captured with a camera or generated with AI. But Apple might be making it a little easier to discern the truth \u2014 if you have an iPhone 18 Pro, that is.<\/p>\n

Apple released three new phones at its September \u2018Surprise and Shine\u2019 event<\/a>, including the first-ever folding iPhone<\/a>, the iPhone 18 Pro<\/a> and iPhone 18 Pro Max<\/a>. It also introduced a new kind of \u201cdigital negative\u201d for your iPhone photos, called reference images. Reference mode can be used to verify the authenticity and provenance of your original photo \u2014 in other words, that it\u2019s a real photo taken by you.<\/p>\n

Apple\u2019s new reference image technology starts the moment you capture a photo. Apple\u2019s approach is different than other content provenance methods, including the widely adopted C2PA standard<\/a>. Apple wrote in a technical paper<\/a> that software-based methods for tracking changes are \u201cvulnerable to compromise at any point in the editing chain, and a viewer has no way to detect such a failure.\u201d So the company is betting on its own new hardware-integrated solution built directly into the photography process.<\/p>\n

As for AI-generated media, Apple said it will support SynthID, a Google-led content authenticity initiative<\/a> to embed invisible markers in AI content created with Apple\u2019s Image Playground<\/a>. Note: iPhone owners in the European Union and China will not have access to reference images at its launch.<\/p>\n

How to use Apple reference images<\/p>\n

Reference mode, which relies on a brand-new camera sensor found only in the new iPhone 18 Pro and iPhone 18 Pro Max, is an optional feature that requires your iPhone to be running\u00a0iOS 27<\/a>. In your iPhone\u2019s settings, go to Camera, and toggle on the Reference Image setting. Now, when you open your camera, you should have a new option called \u201creference,\u201d just like you would choose between photo, video and other modes. <\/p>\n

When shooting in that mode, the camera sensor is booted up and adds signature data to the raw data of your photo. This happens on a pixel level, the smallest unit of a photo that\u2019s editable. Apple\u2019s private cloud compute<\/a> takes that signature and turns it into a reference image you can view in the Photos app, and you can use the feature when you\u2019re offline. <\/p>\n

While private cloud compute is also used to run Apple Intelligence, no generative AI is used to create your reference image. This is just Apple\u2019s \u201ccloud intelligence system<\/a>\u201d that can handle heavy-duty tasks off-device. Apple says the content of your images is not exposed to the company.<\/p>\n

You can edit the photo captured in reference mode as usual, and use the widget at the top left to switch between the edited and original reference versions. Reference images are intentionally left with almost no processing, so while the lighting and color grading may look very different, they\u2019re still proof of what objects, people and other elements were in your original shot. <\/p>\n

Your reference images are linked with your photo, even after you edit them. They also include a secured timestamp, so you have another layer of proof of when the photo was originally taken.<\/p>\n

In reference mode, you can capture photos in 12, 24 and 48 megapixels, which are rendered into JPEGs. Photos taken in reference mode will eat up more of your storage because they\u2019re larger files, thanks to all the raw data captured in the process. Reference photos are about 8 to 10 MB each, which is about 3 MB larger than regular photos. <\/p>\n

You may not always need a reference image for every photo you take. But for photojournalists, professional photographers and other creators, this new camera mode can help bring another layer of credibility to their work.<\/p>\n

How to view reference images without an iPhone 18 Pro<\/p>\n

Though not confirmed, it\u2019s likely that Apple will add this sensor to future iPhones. With new devices getting increasingly expensive<\/a>, however, we\u2019re stretching out how long we keep our phones<\/a> before we upgrade. <\/p>\n

While you\u2019ll need an iPhone 18 Pro or iPhone 18 Pro Max to capture photos with reference images, you don\u2019t need one of these new phones to view reference images. All you need is a device that\u2019s compatible with Apple\u2019s newest software \u2014 iOS 27 on iPhones, iPadOS 27 for iPads or MacOS Golden Gate on MacBooks. That\u2019s good news for iPhone owners, since iOS 27 is compatible with older phones<\/a> as far back as the iPhone 11.<\/p>\n

To view a reference image, open the file in the Photos app and check for that widget in the upper-left corner.<\/p>\n

Right now, there\u2019s no way for people on non-Apple devices \u2014 such as Android phones \u2014 or outside the Apple ecosystem to view reference images.<\/p>\n

Apple is also adding its reference image logic to iOS 27\u2019s API. This means that developers of third-party, non-Apple apps will be able to integrate the ability to view reference images into their services, if they choose to do so. This could potentially be good for photographers who use apps such as Photoshop, Adobe Lightroom and other services to edit their photos.<\/p>\n

This isn\u2019t a perfect, one-size-fits-all solution. Apple\u2019s hardware solution is inherently limited to devices that are equipped with the necessary firepower to run it. But it\u2019s another solution available to journalists, creators and anybody who cares about photo authenticity. And as our digital world is rapidly being devoured by generative AI, another layer of protection, even if it isn\u2019t evenly spread, is ultimately a good thing.<\/p>\n
