- Evidence of five possible iPhone camera features has been found in iOS 27 code
- These include waveforms, histograms, manual focusing, and more
- It's not clear whether these features will come to existing models or be exclusive to the iPhone 18 series
While iPhones give you a limited amount of manual camera control, such as the ability to adjust the exposure, they don’t really have anything approaching a ‘pro’ camera mode, at least within the official camera app. But that might change with the iPhone 18 Pro series.
MacRumors forum member pdfu has found evidence in iOS 27 of five camera upgrades that could make iPhones far more appealing to anyone who likes to go beyond just pointing and shooting.
These include the ability to display a waveform or histogram to show you which parts of an image are too dark or too bright, and a focus peaking feature, which could highlight the edge of anything that’s in sharp focus, so you can see which parts aren’t. A separate overlay might also warn you when part of an image is overexposed.
Interestingly, there’s also evidence in iOS 27 of an iPhone being able to adjust lens corrections depending on your aperture setting — strong evidence for the rumored variable aperture feature we’ve heard might be included on at least one iPhone 18 Pro and iPhone 18 Pro Max lens.
Plus, pdfu has also found a control that would let you manually focus the camera, rather than relying on autofocus, and there’s a change allowing for repeated self-timer shots — meaning that after one timed photo is taken, the timer can automatically start again and take another.
A long-awaited pro mode
If Apple does add all these features, then it could finally have something approaching a ‘pro’ or fully manual camera mode, which is sure to appeal to some shutterbugs. I’d expect these more advanced features would be hidden away from the standard camera overlay, though, so they shouldn’t get in the way for casual snappers.
Still, there’s no guarantee that all or even any of them will arrive with iOS 27. While evidence of these tools has been found in the underlying code, none of them can currently be activated, and it’s possible Apple will choose to delay or cancel them.
It’s also unclear whether they’ll come to existing iPhones or just the iPhone 18 series. In particular, the aperture changes would probably primarily be aimed at phones with a variable aperture — meaning no current model — and the manual focus mode is reportedly currently locked to phones that ship with iOS 27 or later, which again rules out current models.
All should become clearer very soon, though, as Apple is set to announce the iPhone 18 Pro series along with the iPhone Ultra tomorrow (September 9), and we expect the finished version of iOS 27 to roll out shortly after that.
