Most or many digital edits are over sharpened and often over contrasted from much of what I see. I think sharpness is another one of these subjective things. Even trusting the displayed image to be the true representation of sharpness might not always be safe as there can be adjustments that affect how it is rendered to the screen. I think RT does a good job by forcing you to go to 1:1 to see the sharpening. I thinks this helps to make it more targeted and reasonable but the second you zoom out you can’t see it so that can take getting used to.
I think a lot of images are actually out of focus and that leads to heavy handed sharpening to try to bring something that it did not originally capture.
In the end its what pleases the eye of the creator that matters
I think sharpness really shows up when you print but its a bit harder to gauge it on the display.
Perhaps the details threshold in masking will benefit DT. Opinions on that should start to appear as more uses get access to it in 3.6.
