RAW photos will be saved in the DNG file format, and a separate JPEG file is always saved along with each of them. In Camera Roll and in the ProCamera gallery, RAW photos are displayed in preview size/quality. The actual RAW file always makes use of the full sensor resolution (4:3) – deviating capture formats like 16:9 or 1:1 will only affect the appendant JPEG file.
How To: Open Control Panel (three lines icon, bottom right) > Settings > Photo Mode Options: File format.
A quick new way to change/check the file format is opening the Control Panel. In the bottom left corner, the current file format is displayed. Tap on it to change the file format.
The Editing Suite of ProCamera now also supports RAW files on all devices capable of shooting RAW photos. Once again, this means iPhone 6s, 6s Plus, SE, 7, and 7 Plus.
When editing, RAW files (DNG) remain untouched. Edited versions of the capture will be saved as separate JPEG files. You will notice that the RAW editing includes brand new adjustment tools.
How To: Open a RAW photo in the ProCamera Gallery and tap “Edit”.
