07 Recognise sharpening artefacts
Choose Enhance>Unsharp Mask. Click the square cursor to preview a region in the Unsharp Mask window. Set Amount to 200. By increasing Radius to 10 you can widen the spread of the contrast change. These extreme settings create blown-out highlights, clipped shadows, posterised colours and nasty noise.

08 Sharpen the shot
For a sharper shot with fewer artefacts, set the Amount to 146 for a more subtle edge contrast change. To avoid adding back or white edge halos, don’t let the Radius stray too far above 2 pixels – 2.7 will do the trick in this instance. Drag the Threshold slider to 6 to reduce picture noise. Click OK.
