I have a small GoPro clone from china - sjcam. Obviously not something I use for anything serious but I do carry it clipped on when Scuba diving just incase I see something and don't have my camera with me. One of the things I liked about it is that, as well as 4K vid, it took photos in jpg and RAW. I can't get photoshop or iPhone to recognise the RAW files though. Are there a lot of different RAW file formats? Any idea how I can overcome this?
