Just in case we don't get all adjustments local in Lr4, I'd like to toss in the idea of a local tone-curve adjustment.
If you've never applied local tone curves, you'll be in for a real treat. If you have, then you know what I'm talking about.
1st choice - all adjustments locally apply-able.
2nd choice, top additions to locals, prioritized:
1. Luminance Noise Reduction - preferably with independent detail/contrast controls, but independent controls far less important for NR than for sharpening.
3.a. Tone Curve
3.b. Independent sharpen control settings.
Really hard to decide between independent sharpen controls vs. tone curve.
- We already have local sharpening (and de-sharpening/masking, and the sharpen "auto"masking), and together with local NR, would afford a fair amount of flexibility.
- And we already have basic local tone controls.
But being able to apply a curve allows much better local tone control... I mean fill & highlight recovery would be nice locals to have too, but far less needed once a local tone curve is available...
Likewise, temp & tint would be nice locals to have too, but far less needed once HSL is there...
