Imagine such an image being used as evidence is a court case. E.g. showing someone pointing a gun at another person when that actually never happened.

That threat model has existed since the birth of photoshop et al.

There's a huge difference between someone intentionally altering an image according to their wishes and someone not even aware of changes that have been done.

Before, forensic experts could decide if an image had been altered in photoshop, but I guess the only sane conclusion now is that anything taken with an iphone is fake and untrustworthy.

The article says that “The final composite image should be the best, most realistic interpretation of that moment.” But that doesn’t make any sense. If the there were three real people, rather than one person and two reflections, the algorithm would have created an image of a moment that never existed, stitching together different images taken at different times. The only difference is that we might not notice and mi…

How is what it is attempting to do any different from when someone takes multiple pictures of a group shot, and then uses the different shots to ensure no blinks and "best" expression from each subject? There's a reason professional photogs use the mulitiple snaps mode for non-sports. It used to be a lot of work in post, but a lot of apps have made that easier to now it's a built in feature of our phones.

I’m gonna call bullshit here. The difference in arm pose couldn’t be covered in any reasonable burst period.

Surprised you were downvoted because this doesn't sound right at all.

The poses would be at least a few seconds apart which rules out anything in Apple's computational photography pipeline e.g. focus and dynamic range stacking. At least based on what they have communicated to date.

We know Google demonstrated an AI model that was capable of selecting human parts from multiple photos but that was a showcase feature not something quietly added.

Choice. If I'm using a digital camera I can take 20+ shots of any subject, but then I get to choose which to keep. If cameras don't give you the option for "reality" you're just left with whatever they choose for you no matter how many pictures you take.

So use a non-mobile device with this feature. Nobody is forcing you to use the camera. You know what the camera does, but then continue to use it, and then complain about it doing exactly what you knew it would do. Doing the same thing over and over expecting a different result has a name

Purists will always hate the idea of computational photography, but I love how well my iPhone captures handheld nighttime, low-light, and motion images. I’ve captured some photos at night that I never would have thought possible from a physically small sensor due to the laws of physics. Is it 100% pixel perfect to what was happening at the time? No, but I also don’t care. I’ve used HDR exposure stacking in the past.…

> Is it 100% pixel perfect to what was happening at the time? No, but I also don’t care.

No photographer thinks images the they get on film are perfect reflections of reality. The lens itself introduces flaws/changes as does film and developing. You don't have to be a purist to want the ability to decide what gets captured or to have control over how it looks though. Those kinds of choices are part of what make photography an art.

In the end, this tech just takes control from you. If you're fine with Apple deciding what the subject of pictures should be and how they should look that's fine, but I expect a lot of people wont be.

Scenario: It's a decade from today and phones are not just stitching together multiple photos but also using generative AI. Apple and all of the other phone makers insist the implementation is safe. The suspect appears in the photo doing something they never actually did. In the chaos of the crime, the phone was left at the crime scene where it was found by law enforcement, no chance the photo could have been photoshopped. The photo is shown as evidence in court. Without the photo, there is not enough evidence to convict. The entire case now hinges on the content of the photo. The suspect insists they never did what is shown in the photo, but it doesn't matter. The suspect is convicted, put on death row, and executed by the state. Thankfully, there is a silver lining: everyone's photos are a couple percent prettier, which helped bring more value to shareholders.

I heard mention on a podcast recently [0] that if you hold down the button in the iPhone camera app it will capture a set of photos and then mark the one that it thinks is the 'best' (based on, for example, the photo where everyone has their eyes open). Not the same as what happened here of course. (I keep forgetting to try this, not least because I always try to get the people out of my photos!) [0] This one, I thin…

I think there’s also how the Live Photo feature works. Where taking a photo is literally a short video and it picks the best frame

Unfortunately they changed the behavior a few major releases ago: now holding the button down switches to video recording. Annoying for me, since I don't do video.

If you use the software button you can slide to the left for burst, but afaik there's no way to trigger burst photos from the volume buttons. Maybe the new programmable button on the iPhone 15 series.
