Photon, an iOS app for pro photographers, is introducing a new feature that will allow iPhone 15 Pro users to save their photos directly to an external drive, freeing up valuable disk space on their device. The app, which hails from LateNightSoft, the makers of the popular consumer app Camera+, was launched this July to cater to a more professional audience with tools for adjusting focus, shutter speed, ISO, white balance, format and resolution, among other things. The new feature isn’t an export option, which can be time-consuming, but actually a way to directly save photos to external storage. To get started, users have to toggle on the option in the app’s Settings (the button in the bottom-right corner of the screen). From there, you’ll tap “Capture” and enable the option “Use External Storage.” You can then plug in your external drive and start taking photos.
