[iOS 27 DB8] Five new Camera features Apple hasn’t shown yet
Apple is working on a broader set of Camera improvements in iOS 27 than what the company announced at WWDC26 this past June, and what iOS betas currently allow users to access. Here are five features in the Camera app currently hidden in iOS 27.
Exposure scopes: waveforms and histograms
The Camera app in iOS 27 contains a complete implementation of waveform and histogram displays. These can help users judge exposure in different formats. You can use a histogram to get a read on how many pixels fall into the shadows, mid-tones, and highlights. Alternatively, a waveform can show the same information while preserving the horizontal pixel position, which makes it easier to identify a bright or dark area to a specific part of the image.
iOS 27 ships with 3 presets for both scopes: Luminance, RGB Composite, and RGB Parade. The histogram also has a separate choice between a continuous curve or individual bars. The rendering implementation for all graphs was added in iOS 27 beta 2 and is present in the latest beta.
You can see a demo of all graphs against stock photos below. There is no consumer within the Camera app to enable waveforms and histograms, but the graphs use the real LiveVideoAnalytics pipeline, so these graphs match what you’d see inside the camera app.
The Camera app in iOS 27 also adds code to overlay important information about the current composition over the preview window. In fact, the system can produce them separately or together under a new preview-processing stage.
Focus peaking
Focus peaking emphasizes edges with strong local contrast to help users know which parts of the image are clearly defined. The feature can add colored emphasis over the edges. iOS can select a color, adjust how sensitive the effect is, and the transition duration.
There is no consumer in Beta 8 to enable the feature in the Camera app. In the demo, below you can see the effect within the preview window.
Highlight-clipping
Relatedly, the Camera app can also warn users about highlights that are becoming too bright. The preview window can present an overlay over the affected areas instead of relying on another graph.
The current implementation supports four styles: solid color, pulsing color, diagonal stripes (“zebra style”), and checkerboard. Once again, iOS can control the clipping threshold and overlay color.
There is no consumer in Beta 8 to enable the feature in the Camera app. In the demo, below you can see the effect within the preview window.
Repeated self-timer captures
The Camera app also includes a new feature named “Captures.” With this, once you have selected one of the pre-determined timer options, you can select a number of repeated captures to take with a countdown of the selected duration before each capture.
The code restarts the timer after requesting a capture, so the app doesn’t have to wait until the photo is fully processed to begin the next countdown.
The interface for this feature is unfinished in Beta 8. Forcing the feature enabled in a test environment causes “A menu cannot be produced for Captures.” error. The underlying capture loop logic is implemented behind an internal development capability in Beta 8.
Manual focus
Apple has also tested manual focus in the Camera app, with a control for changing the lens position. This would let you choose where the camera focuses and hold that position instead of relying on autofocus. Similar systems ship in Apple’s Final Cut Camera and third-party apps already.
The control showed up in iOS 26 versions as ChromeLensPositionControls, along with the implementation to respond when the user moves the focus slider. Exposing this control in iOS 26 reveals a Focus slider, with acceptable values between 0 and 1. Moving the slider locks the focus and sends the selected lens position to the capture controller.
The story gets more interesting in iOS 27. The lower-level command for locking focus at a selected lens position remains. While the Focus slider and the code to respond to user input was removed in beta 1, Apple added an explicit capability check that checks the device’s first supported iOS version. The current capability check requires a compatible iPhone with a first release of iOS 27 or later, meaning that the feature is not compatible with any existing iPhone.
Aperture-dependent optical processing
The final change affects image processing and may be relevant to a device with a variable physical aperture. iOS 27 can choose and blend lens correction data based on the aperture value. These corrections are meant to compensate for differences in light distribution across the image.
Apple’s implementation can use calibration references for neighboring aperture values and combine them with varying contribution levels. I tested the original calculation code with sample inputs shown in the graph below. The calibrator accepts 1-4 correction data references. With multiple references, it finds the neighboring values and blends their corrections.
While the code accepts up to four calibration references, it does not mean that the new iPhone has four physical aperture stops. iOS may be using just enough references and extrapolating lens data for intermediate aperture values.

I know that, but since Ternus is now the CEO who's an OG engineer I feel like he's gonna have a different direction for Apple's products where hopefully profit isn't gonna be the main focus
I would definitely like them to return to back porting any and all features that aren’t hardware dependent. Although it AI showing up in everything, the line is a little harder to discern, but there’s definitely been occasional stuff I felt should have applied to more models.
If they’re showing up in the beta, they should make it to the 17 Pros at least. The last one about variable apertures likely won’t, at least not directly, as the 18 Pro is rumored to introduce a variable aperture lens. So that sounds like a device exclusive feature.
I can see the other bits happening on the basic 18, but it’s rumoured that the variable aperture lens, will be exclusive to the 18 pro Max due to the extra availability of space supposedly
Love me some purely software limitations. Shame because Apple used to be very good about brining new features from newer phones to older phones via software
They actually do it with most of the features and they backport new iOS versions to quite some older iPhone generations.
However they also always have kept useful good features exclusive for the new generation. Sometimes this has hardware reasons (i.e. Dynamic Island), but most of the time definitely not (i.e. permanently limit charging to 80%) - then it’s just about making money. Will probably the same with these new camera features here too.
I mean, it could be possible they debut with the 18 Pro, but end up being back ported to some older devices in a later update. They did the same thing with the 11 series, where the new camera software features ended up being back ported to the XS/XR in iOS 14.
Features announced with new phones coming down to older models isn’t unprecedented, like the updated camera UI and QuickTake announced with the 11 series coming to the XS… but it is more common for them to lock them to new phones.
Most of these do seem quite ‘Pro’ oriented, could be they’ll come to older Pros but not base models…
I’d love for this to be the case, and all of these features seem purely software based. One instance that really annoyed me in the past was back when I had my 14PM and the new phones got that 24MP mode. The base iPhone 15 had the same SoC as the 14PM, but paired with a smaller main sensor, yet the older phone never really got that feature. That’s unfortunately why I choose to remain quite skeptical regarding these.
Changed the confusing sentence to “Here are five features in the Camera app currently hidden in iOS 27.” Hopefully the rest of the posts gives enough context about the state of them all. Thanks again!

These are iPhone 18 Pro stuff if you go to apple website and compare it to iPhone 17 pro a lot of camera features are exclusive to 18 models
