you get to the desired result.

I unsharpened with radius at 5, threshold 15, and amount .5.

When I finished the process.  I viewed the image at 100% and it was terrible.
Any recommendations regarding the process or the unsharpened mask settings?


It makes a difference what type of image it is. Enlarging a jpg will give worse results than enlarging a tif or raw, for example. Try decomposing the img into LAB and sharpening only the L layer.
