Something weird is going on. Noticed it before 2.6, but came across it today at a larger scale:

If I use a local adjustment brush, it doesn't just affect only where I paint, but it does something (unrelated to the "effect" I', brushing in!) to the entire image: It clips highlights.

Example: Local adjustment brush "darken", before and after clicking once on the eye.
Notice the detail in the top of the mic and the shirt getting blown.

Before and after screenshots, to big to post here. My monitor profile embedded, so colormanaged browsers should display correct, but I think the difference will be visible anyhow.

Same happens if I set only exposure to -0.4, everything else "0".
The eye get's darker, other details (way, way away from the brush) get blown.

Same happens when I use a graduate filter.
Same happens if I click the top right corner for that matter...

So, in order to get the image about like I want, I have to use an extremer -EC grad in addition to the local adjustment brush I want to use... Still, it's not perfect, and detail that should be there, get's blown.

Any ideas?

Yes it's a bug, and it's not new to 2.6. I had a conversation about this about May last year, but some of the local adjustment math needs redoing and that was going to be a big job that wouldn't be done before 3.x at the earliest.

Ah, so basically, I'm outta luck? That sucks.

LR3 won't run on my (PPC) Mac.
If I have to use PSCS4, I think I'll stick with DPP instead....

It only shows up on odd occasions - I've only heard you and one other person complain about it (don't you feel special!) so probably, yes, on this one.

:mrgreen:

I think it's somehow related with the way the "Recovery" slider behaves: Also somewhat odd. (or at least somewhat unexpected sometimes on saturated hightlights.)

Ah well, time to rethink the options of Raw conversion then..

To bad DPP isn't perfect in cases like this either. :(

I would assume recovery would get attention at the same time.

How often is this causing you a problem though? The occasions I've been able to replicate are pretty unusual situations (flames, that kind of thing).

Just edited a shoot today (58 shots) and now I know it, I notice it on most shots I use a local adjustment on. So I'd guess it's probably "affecting" in 10% (rough guess) and probably present in 75% of the shots I use a local adjustment on. But not in an 'important' way.

Like I said, I've noticed it before (2.4 or so), but at the time I assumed the "falloff" of the mask wasn't "steep" enough when dodging something for instance. This time I noticed it happened right when applying any brush, even with a "burn" setting.

Yeah, or performing arts, which is 90% of what I use LR for: I use DPP/PSCS4 for most other (non-reportage) work. ;)

From what I remember it was limited to the exposure slider on the brush, so you could try brightness and see if that solves it.
