I recently got around to upgrading from COPro8 to Pro 9 but have yet to play with the layers, but the colours seem to be pretty faithful for my Olympus ORF raw files.

I know Larry in Queensland is using it & thanks to him I went for the upgrade.

BTW, I've updated to 9.0.2 but don't know where to find (online) the details for what each update adds. Any help there?
