Quick Answer
The native iPhone Camera app always saves to internal storage — there's no setting to change this. However, on iPhone 15 Pro and later, you can record ProRes 4K video directly to a USB-C SSD by connecting the drive and enabling External Recording in Settings > Camera > Formats. For photos, use a third-party camera app like Halide, Pro Camera by Moment, or ProCamera that supports saving to Files (iCloud Drive, Dropbox, NAS, USB-C drives). Or move photos to a different location after capture using the Files app.
Step-by-Step: Direct USB-C Recording (iPhone 15 Pro+)
1 Connect a Compatible USB-C SSD
Plug a USB-C SSD into your iPhone 15 Pro or 17 Pro's USB-C port. The drive must be formatted as APFS or exFAT and have sufficient free space (ProRes 4K is 6 GB/min).
2 Open Settings > Camera > Formats
Go to Settings > Camera > Formats. Scroll to Video Capture and toggle on ProRes.
3 Select External Recording
Under ProRes settings, choose 4K 60fps and tap External Recording. iOS confirms the connected drive.
4 Open Camera and Record
Open the Camera app, switch to Video, and start recording. The footage saves directly to your SSD instead of internal storage. A small SSD icon appears next to the record button.
Method 2: Third-Party Camera Apps
5 Install a Pro Camera App
Download Halide, Pro Camera by Moment, or ProCamera from the App Store. These apps offer custom save destinations.
6 Configure Save Location
In the app's settings, find the save destination. Most pro camera apps let you save to Files (which includes iCloud Drive, Dropbox, OneDrive, NAS shares, USB-C drives, and more). Choose the destination and start shooting.
Method 3: Move Photos After Capture
If you want photos in a different location, the simplest method is to capture normally then move them with the Files app:
- Open Photos, select photos.
- Tap Share > Save to Files.
- Choose a destination — iCloud Drive, USB-C drive, NAS, or local folder.
- Optionally, delete the originals from Photos to keep only the moved copies.
