OK, I mentioned that I would post about the clarity slider and what the new negative clarity can do, and this is it.
There’s not much I can say that a photo can’t say. The slider goes from -100 to +100 rather than 0 to +100 as in Lightroom 1. The negative clarity manifests itself as softness and blurriness. I find using negative clarity awesome for portraits, to give them a very nice glow and smoothness.
This image uses clarity applied to the entire photo. Another way to do it in LR2 would be to use the adjustment brush to have localized softness in a sharp photo. And, of course, the opposite is true. The adjustment brush is awesome.
