View sharpening changes - how?

[stayathomedad]

I want to view my sharpening changes in fit or fill, not just 1:1...

Is there any way I can do this besides exporting the image?

Zoom in to 1:1 view, and then view the Fit or Fill view in Library module. Or if there's more images, select them in Grid view and go to Library menu > Previews > Render 1:1 Previews.

1:1 previews have all of the sharpening and noise reduction applied. Library module uses the pre-rendered previews, and will scale it when viewing a Fit or Fill view.

And the other point to complete Victoria's thought -- the smaller previews will not include sharpening or noise reduction unless the 1:1 previews have been built.

Lightroom only applies sharpening and noise reduction to previews when it builds the 1:1 preview, in order to save time. The smaller previews are then downsized from that.
