Silver B&W Camera supports RAW and ProRAW (since version 3.1) formats. RAW and ProRAW images are combined with JPEG or HEIC photos as a single image file.
By default a JPEG or HEIC version is shown and shared if send to others. The RAW and ProRAW versions remain in the background and needs specific actions to be accessed.
You can use Mac computer and Photos app to extract separate RAW or ProRAW and JPEG or HEIC files.
Or you can use iOS app like A Photo Tool to select whether you want to access the RAW format or normal photo format of the file.
We have a short video to show how everything is done. See it here on YouTube.
