I shoot with a Canon, and when I first look at a picture in DPP, I generally turn up the sharpness to 3 or 4 (with portraits).
Recently I began learning some new tricks with retouching portraits, and I am now wondering if this is best practice or not? Since the last thing I do now is apply a USM to the photo anyway? Maybe it doesn't matter?
What is your sharpening 'work flow' (for portraits).
For that matter, I also usually add a tick of conrast and saturation in RAW too. Any other tweaking I do in GIMP.
