What does not work as described in the documentation?
Images created from my various iPhone models that support the Apple ProRAW image type are not rendered properly in the PhotoPrism WebUI. See example:

How can we reproduce it?
Steps to reproduce the behavior:
- Import images taken on an iPhone using Apple's ProRAW image format to your PP library.
- Browse the images via http://photoprism..net/browse
- Click on any of the iPhone ProRAW image to view full screen. (Note the image thumbnails also render improperly.)
- See error
If reporting an Import, Indexing, or Performance issue, please include the number and type of pictures in your library,
as well as any configuration options you have changed e.g. for thumbnail quality. There are about 60k images in my library.
What behavior do you expect?
I expect the image to render in a viewable state similar to how Sony .ARW RAW files or Canon .CR2 RAW files are rendered.
What could be the cause of your problem?
As I understand, PP uses upstream software - DarkTable & RawTherapee to render JPEG previews from RAW images. Darktable appears to not yet support iPhone ProRAW files - refer to DarkTable GitHub Issue
Is there an alternative way PhotoPrism could render these images? I do not know the number of PhotoPrism users who 1. use an iPhone for photography and 2. use the Apple ProRAW file type, however I would be surprised if it were not a significant percentage of users.

NOTE:
- You have to provide sample files and logs if it is an IMPORT, INDEXING, or METADATA issue, otherwise we will not be able to process your report
- If it is an IMPORT issue, please also provide an archive with affected files before importing them so that it's possible to reproduce your issue
Which software versions do you use?
- PhotoPrism Architecture & Build Number (220302-0059f429-Linux-AMD64)
- Database Type & Version (MariaDB)
- Operating System Types & Versions (PhotoPrism running on Linux in Docker)
- Browser Types & Versions (Firefox 99.0.1, macOS 12.3.1)
- Browser Plugins & Ad Blockers (Bitwarden)
The app version / build number can be found in Settings when you scroll to the bottom.
MySQL 8 is not officially supported anymore, see System Requirements.
NOTE:
- Always provide database and operating system details if it is a Backend, Import, or Indexing issue
- Always provide web browser and operating system details if it is a Frontend issue
- If it is a Performance problem, you must provide ALL information
On what kind of device is PhotoPrism installed?
This is especially important if you are reporting a Performance, Import, or Indexing problem. You can skip this if you are reporting a problem found on our public demo, or if it is a completely unrelated issue, such as a broken page layout.
- Device / Processor Type (Unraid custom server build, i5-8400)
- Physical Memory & Swap Space (48GB physical memory, unclear swap size)
- Storage Type (TrueNAS ZFS Array mounted to linux server via NFS. Linux server provides the storage to Docker where PP is running)
- anything else that might be helpful
NOTE:
- Always provide device, memory, and storage details when you have a Backend, Performance, Import, or Indexing issue
Do you use a Reverse Proxy, Firewall, VPN, or CDN?
Firewall- pfSense 2.5.2 on dedicated physical host. Runs a few remote access VPNs. These should be out of scope of my photoprism issue.
NOTE:
- Always provide this information when you have a Reliability, Performance, or Frontend problem, such as failed uploads, connection errors, broken thumbnails, or video playback issues
- If you are using NGINX, also provide its configuration and/or consider asking the NGINX community for advice as we do not specialize in supporting their product: https://docs.photoprism.app/getting-started/proxies/nginx/
