Hidden iOS 27 Code Hints at Major Camera Upgrades for Future iPhones
Apple appears to be preparing a significant overhaul of the iPhone Camera app, according to a detailed analysis by MacRumors forum member "pdfu." The findings, based on code found within the iOS 27 beta, point to five new features that could debut with upcoming iPhone models or arrive later through a software update.
The first feature involves exposure scopes, which would let users view a waveform or histogram while shooting to better judge exposure levels. A histogram shows which parts of an image are too dark, too bright, or balanced, while a waveform provides similar data while preserving the spatial position of those areas within the frame.
A second addition includes focus peaking and highlight warning tools, which overlay real-time information directly onto the camera preview. Focus peaking would outline sharply focused areas in color, while a separate overlay would flag overexposed sections using solid colors, pulsing effects, diagonal stripes, or checkerboard patterns.
The code also reveals a new repeated self-timer function, allowing users to capture multiple timed photos in succession. Instead of waiting for each image to save before restarting the countdown, the timer would begin again immediately, enabling faster consecutive shots.
Another feature involves manual focus control, giving users the ability to lock focus manually instead of relying solely on autofocus similar to functionality already found in Apple's Final Cut Camera app. A similar tool existed in iOS 26 through a focus slider, which was removed in the first iOS 27 beta. However, remnants of the underlying code remain, though Apple has limited its use to devices launching with iOS 27 or later, meaning current iPhones will not support it.
The fifth feature centers on aperture-based image correction, a process that may be linked to a future iPhone equipped with a variable aperture lens capable of adjusting its opening rather than remaining fixed. According to the code, iOS 27 could adjust lens corrections based on aperture settings, blending between as many as four reference points for improved image accuracy.
While these features could eventually extend to multiple iPhone models, the presence of aperture-based correction aligns with rumors that the upcoming iPhone 18 Pro may include a variable aperture main camera suggesting some of these tools could debut with that device.
None of the five features are currently accessible in the iOS 27 beta, and Apple may choose to withhold some or all of them from the software's public release in September.
This discovery follows other recent code-based findings from pdfu, which previously uncovered evidence of unreleased game controllers, a four-speaker HomePod surround sound system, and new details related to future Apple Watch models.
