Hello Ron.
This has been a useful exercise, thank you for starting the thread.
I have found a foliage image, so now have experience with two photos as against your 3,000+.
With that caveat it seems to me that at this level, we are discussing whether we are looking for sharpness or detail, and how we want to draw the eye of the viewer, so there is a large subjective component to the workflow we settle on. That's not a bad thing if we don't want our processing to look the same as everyone else's.
One problem for me is that in the past I would take the amount slider in LR right up to see the effect of the other parameters, then drop it down again. This isn't working in LR 6 with the X-T2 files. The effect is ghastly.
I think I'm getting the sharpest result with:
Amount 20, Radius .8, Detail 10 and masking 10. Then the two step sharpening in Nik.
The LR values are a little arbitrary, but get me in the ballpark.
The result is not crunchy or over the top, but sharper than I want for the way I see the world in my photographs. So if I want to use the Nik software I will leave out the LR step, and probably knock the Nik step back 20% for the papers I use for printing.
It would be interesting to try sharpening with Nik after a raw conversion with PhotoNinja or Iridient.
I wasn't expecting to have to change my approach so much with the new camera. Cripes it has a lot of detail.
Cheers,
David
