Ok, thanks for that info. So Q1 has its own default rendering of the raw data? Is it the same as QU? macOS default?
Raws that are well exposed and don't need a lot of editing should have similar default renderings across Ultimate and One. Beyond that, the scenarios can get complicated. Ultimate allows the user to change raw processing options to change them from the defaults. And since macOS has system level support for raw photos, the Mac version of Q1 will render raws like other macOS tools to be consistent across applications on the Mac... but that also means that raw photos will not necessarily be identical when comparing Q1 macOS to Q1 Windows.
Since all raw developing tools come with their own "flavor" of how the raws are developed, we tried to keep things consistent among tools on the same OS. So Q1 Windows will be a good match for QU Windows (with QU defaults). And Q1 macOS will be a good match for other macOS tools like Photos. We felt it was important for macOS users to get raw photo results similar to what they were used to seeing with other macOS tools rather than try to emulate the same results between macOS and Windows since few users tend to switch back and forth between macOS and Windows applications.
As previously mentioned, nearly any tool will produce similar results when developing "typical" raw photos. For those with challenging scenes, difficult lighting, under or overexposure, we feel like users will likely use their favorite raw developing tool to do the more complicated edits anyway and they will be exporting and then using Q1 to print, or using the including plugins to come from Photoshop.
