If one were to set the Detail to 100, would this carry through to the Sharpening slider when using the Adjustment Brush in ACR? If so, that would go a long way toward selective application of the deconvolution method, possibly as good as painting it in from a layer mask.
Yes, Walter. It does means you can apply this type of sharpening / deblurring selectively, if you wish. There are two basic workflows for doing this in CR 6 and LR 3.
The first way is just to paint in the sharpening where you want it. To do this, you set the Radius and Detail the way you want, but set Amount to 0. Then, with the local adjustment brush, you paint in a positive Sharpness amount in the desired areas. The brush controls and the local Sharpness amount can be used to control the application of it. (Of course you can also use the erase mode in case you overpaint.) This workflow is effective if there are relatively small areas of the image you want to sharpen. I tend to use this for narrow DOF images (e.g., macro of flower) where I only care about very specific elements being sharpened. It also works fine for portraits.
The second way is the opposite, i.e., you apply the capture sharpening in the usual till most of the image looks good, but then you can selective "back off" on it (using local Sharpness with negative values) in some areas. Of course you can also add to it (using local Sharpness with positive values).
