How to address over sharpening

I often receive over sharpened images from my clients.

As suggested by: http://www.cambridgeincolour.com/tutorials/image-sharpening.htm

  • Grossly over-sharpened images can sometimes be partially recovered in Photoshop by (i) duplicating the layer, (ii) applying a gaussian blur of 0.2-0.5 pixels to this layer 2-5 times, (iii) setting the blending mode of this top layer to “darken” and (iv) potentially decreasing the layer’s opacity to reduce the effect.
