"and cleaning up after auto mask. "

I would be very opposed to them designing a tool to clean up after the failings of another tool. I'd rather they spend that time fixing the failings!

Fringing (longitudinal CA) is something that's really hard to correct properly. I wonder if there's a simple way to be more effective than the current fringe tool which seems to have too small of a radius.

Eric, I have tried creating a lens profile, but I found it challenging to do with a 600mm + TC14. The profile I created did not resolve the CA issues. I agree with you that localized CA is a kludge (suboptimal). I was just looking for a quick hit.

As I think about this more what I really want, in the short term, is a fringe removal brush, that would deal with fringing, tough CA and halo issues. This would be extremely useful for CA, fringing and cleaning up after auto mask.

Rory, you could, but frankly local CA correction is very suboptimal (you wouldn't want to be doing this on every image, separately). Have you tried using lens profiles instead?

sascha, you can already do local sharpening in LR2 and LR3.

We're not keen on making intermediate rendered versions on disk, partly because writing huge temp files is also a big performance hit, and partly because that eliminates the non-destructive aspects of the workflow.

ok, if i have to select my top ones, it would be color and sharpening

concerning the performance, is it not possible to have two local adjustment versions, the current one, and an advanced version, this then triggers an internal copy of the image (on the HD) where you make all changes persistent, so you do not have to calculate all on the fly?
so fake it for the cost of disc space ... as role back to original still possible

I have situations with long lenses (600mm) showing both blue and red CA where LR can only correct for one or the other but not both. If I could apply CA locally then I could completely remove the CA. BTW, nikon software can completely remove the CA.

I'm surprised by #3.

I appreciate your feedback on this topic Eric, especially regarding to your comment about the "current design". In the longer term (but not too long ;^)) I would like to see a redesign. In the short term, the items I would like to see added, if feasible, in order of importance to me:

1. Noise reduction
2. Recovery
3. Chromatic Aberration

Finally, I would like to see improvements to auto mask on high contrast edges to prevent halos.

For performance reasons we can't reasonably do ALL adjustments on a local basis, at least not with the current design. We have to focus on what makes sense to localize the most, i.e., what would be the most useful, provide the most bang for the buck. Photographically, for example, it makes sense to want localized exposure, but probably not localized keystoning (though certainly would be an interesting effect ...)
