Thanks for the replies.
So far, I've been copying and applying globally. That's no problem.
And, from Doug's answer, it would appear that applying one edit, from a given tool, via the double arrow, is no problem either.
So, my next question is, what if I want to apply edits from two or three tools, but no more than this, from one image to all other images?
In Lightroom, you would simply check those tools (leaving all the others unchecked) in the check box dialog.
What's the equivalent in C1?
Thanks again.
