Hi @ben975 - The Color.io App ( app.color.io ) does support .CR3 files as it is a fully capable RAW image editor. Please let me know if you're running into any issues opening your files in Color.io.

Match AI ( match.color.io ) does not support any kind of RAW image processing and is limited to JPEG and PNG. If you want to create LUTs using Match AI and not Color.io, you could still do this:

• open CR3 in app.color.io
• set input color space to VisionLog
• export image as JPG
• drop JPG into match.color.io and export a LUT
