A few things to be aware of the RAW feature
You will have an option to shoot in RAW if your subject’s phone camera supports this format: all iPhones from 6s and most of the modern Android phones. But please keep in mind that not each camera on the phone can support the format 😞
For instance, iPhone 7 has back-facing and selfie cameras, but only the back-facing one supports RAW. Or, take iPhone 12 Pro, it has 4 cameras and you can shoot RAW with each one of them!
One more tip. When your client has an iPhone then take one photo first and the RAW will become available ☝️ This is a known issue with Beta and will be addressed in the next update!
