Dual camera, any two lenses · On supported iPhones, pair two back lenses (for example Wide with Ultra Wide or Telephoto), not just front with back · Choose the second lens, picture-in-picture or split screen, and the picture-in-picture size · A rear second lens can match the main lens's exposure and white balance, and its photo is taken at the same moment · Files are named after their lens (-UW, -W, -T) and still show up as one dual item in the library · Dual video keeps a responsive viewfinder with cinematic stabilization Viewfinder aids · Live histogram or waveform next to the Dynamic Island; tap to enlarge and switch between luminance, RGB and waveform · Zebra stripes and false color, shown on screen only, never in your photos or videos · Readings are taken from the RAW or Log negative before filters · Grid settings now live in More › Viewfinder aids Camera layout · The Filters button sits beside the shutter and shows the current style; touch and hold it to turn all filters on or off · The flip button moves to the end of the zoom bar; the bottom rail holds exposure controls only Fixes · Lower power use: camera modes you've left no longer keep drawing the viewfinder · Battery level now shows in the viewfinder · Improved translations

Flash · Godox A2 support: manual power, TTL and auto exposure, plus control of the A2's fill light from the app · Tap the A2 over NFC to connect, and the camera reconnects to your last A2 automatically · More Godox Bluetooth triggers: X2T, XPro II and X3Pro (experimental) · Flash, fill light and Godox now share one light console under the viewfinder · Trigger mode is more precise: it follows the iPhone flash rhythm with a pre-flash before the main flash, timed to the viewfinder frame · Godox flash settings are recorded in the photo's metadata Panels · Filters, Format, Landscape and More are now fixed-height panels under the viewfinder: no jumping between tabs, nothing covering the frame, and hints tucked behind ⓘ · The editor tray and batch filters use the same layer panel Filters and film · The Film layer is now called Camera, with a new Film tone option: LUTs on top keep the film tone and only change colour · Texture recalibrated against real iPhone samples: grain stays visible in small previews, fade and vignette are gentler.

Existing recipes keep the old look · AV105: sunlit faces no longer turn orange-yellow Camera · After you tap to meter somewhere off-centre, metering returns to the centre once the scene changes

Pick a frame colour; the mini contact-sheet style prints each photo's own shooting details along the edge · New Texture layer: grain, fade and vignette, stackable with film, LUTs, the palette and lens filters · Works in the camera, the editor, and time-lapse / stacking Exposure · On variable-aperture iPhones, the settings rail gains an Aperture control. Aperture, shutter and ISO can each go auto: aperture priority, shutter priority or ISO priority Fixes · Button labels on the stacking error screen and the Film layer
