Canon shipped their newest and cheapest full frame camera, the Canon EOS RP, end of February. In their infinite wisdom, they decided that they had to to develop a new CR3 format for this as well as the previously released EOS R and M50 cameras. And of course, so far no one was able to reverse-engineer the raw format entirely, so it will take a good while until those cameras will be supported by all major open source raw programs out of the box. The last option is running the Adobe DNG Converter in a Windows VM or under Wine to convert the proprietary CR3 format into their (intermediate) DNG format. After a good month, Adobe released a new version that supported the RP … but it stopped working under Wine 🤦. So, whoever stumbles upon
Unhandled exception: unimplemented function api-ms-win-core-winrt-error-l1-.GetRestrictedErrorInfo called in 64-bit code
winecfg, go to Libraries, add two entries for
api-ms-win-core-winrt-error-l1-1-0 and deactivate them. The DNG converter will
complain but it will work (much faster than in a Windows 10 VM!) nevertheless.
