Expert RAW supports HDR with the ability to save and store images in lossless JPEG and 16-bit linear DNG RAW formats. Integration with Adobe Lightroom is also included, with the ability to open RAW images directly in an image-editing application using a toggle in the camera. There are even profiles for even more convenient editing.
The Expert RAW app is currently only available for the Galaxy S21 Ultra. A recent update added more features and fixes to the app, which unfortunately is still not officially available outside of South Korea.
According to a post on the official Samsung forum, the Expert RAW app will be available for more Galaxy devices from February 25th. It's also worth noting that this post assumes that this date will mark the launch of the stable version of Expert RAW. This may mean that the application will finally become available in other countries.
An official list of devices has not been released, but Samsung has noted that these are high-end devices (probably the Flip and Fold lines) and the Galaxy S22.
