I'm currently using CS6, and have fairly recently added the Nik Collection, including Sharpener Pro 3.  Doing lots of reading, I've realized that I really don't have a good grasp of pre-sharpening.  Most of the articles / tutorials, whatever, say something nebulous along the lines of, "you just want to take away some of the inherent softness caused my digital imaging and anti-aliasing filters; don't overdo it here."  Not a lot of help.  I've been using the ACR sharpener, set at 25, based on something I read here, years ago.  Can anyone provide me better info/guidelines?  Is what I'm doing fine?  Would I be better off using the Nik pre-sharpener?  At what setting?  Is it image / subject dependent?  All in all, I think I do OK, but am always willing / eager to learn more.
Thanks in advance.

The first question would be what camera are you using? Depending on model, it may not have an AA filter...

OK, that has a very strong AA filter as do most Canon cameras. I think your current settings are appropriate for that camera.

Yup!  Canon cameras use relatively strong AA filters.

Not to let a good thread die. Any idea what the pre-sharpening settings in ACR and C1 should be on a Sony a7R3?

I don't know about the current version of ACR but C1 automatically picks the setting that Phase One came up with for that camera - it's part of the unique camera profile that they come up with for every single camera that they support.  I find that these are often a bit too harsh and back off the amount about 33% from the preset.

That's an interesting suggestion regarding C1, E.J. I changed the sharpening default to zero when I noticed Phase One's heavy handedness, but will give the reduced amounts a go.
