Settings

Behind the gear in the camera's top row, next to RAW in photo mode and next to LOG in video mode.

The switches

Changes take effect as soon as the sheet closes.

SettingWhat it does
Save RAW (DNG)On by default. A Bayer DNG is attached to every shot. The RAW pill in the camera is the same switch.
Save LocationOn by default. Where a shot was taken goes into the HEIC and the DNG, and into clips, so Photos can place them on its map. Off, nothing about the place is stored.
Photo Look / Video LookNative by default. The look every new photo, or clip, gets in the Gallery as it arrives; the camera itself still captures the plain frame and the RAW. Any shot can be given another look afterwards.
Export at 2×On by default. Every saved or shared picture is resampled to twice its width and height. The DNG is never resampled.
Sync My Looks with iCloudOn by default. Your own looks follow you to every iPhone on the same iCloud account, sealed.
