thank you very much Bobby,In C1 Pro, there are a great many more color tools which could be used to really refine the reds exactly to your, or each person's preference. Unfortunately, the first time purchase of C1 Pro can be costly. Even the upgrade price has gone up. On the other side of that, C1 Pro is at a point for many photographers where it is the only editing software needed. I've been away from Adobe for quite some time, with the exception of occasional testing of new versions. And only use Affinity Photo if I need a content aware brush. Which is rare.
Your article gives a great starting point for getting the look of X-Pro1 files. I don't think that I ever would have thought to try the edits you did to get to the starting point.
I know this is a sentiment that you probably won't share.... :-D
But bar the missing perspective correction, I think I actually prefer express as it's simpler and has less repeated functions.
Of course (like you) I have other apps that can do layering and cloning etc if I need them, without these tools I'd probably be more sold on C1 pro (to be fair it would nice to have a one stop app that didn't require a tiff/whatever farmed out to other apps when I needed greater editing tools, but for the cost of C1 I can get by as I am)
