Local Adjustment brush halos
Hi there,
Just want some technique advice by some experts here...
I took a series of exposures for HDR and non-HDR scenes with lots of shadows and highlights.
For the most part, I could use Local Adjustment layers on a single exposure to fool around with the areas that need a little highlight or shadow help and probably not go through all the trouble of doing HDR exposure / tonemapping.
However, even when I'm using my tablet PC stylus with pressure on, a sufficient brush tip and 0% hardness, it seems like Local Adjustments often leave a "halo" around the adjustment area boundary of the image if you're not super careful.
Example (not my own):
You can see a light halo above the Tree Line if you look at this Phase One blog post:
They are far more noticeable if you try to reduce exposure (highlight recovery).
If you have any awesome techniques, let me know!
Thanks,
TTFN

That's probably when I have a complex interface, like trees against a sky, I'll revert to Lightroom 4, which has an "auto mask" option as part of the local adjustments. It works pretty well.
I think it also does shade and highlight recovery better, especially when a photo has both very dark shadows and very brightly lit sunny areas.
That said, I still use CO 80% of the time.
There is no perfect software solution.

So LR4's masking is a bit more precise for that type of activity?
I haven't tried LR4 for that specifically (I don't own it, but may give it a shot).
I'm familiar with layer masks and selections in CS5 of course, but I wasn't sure that type of selection was in LR4.
I'm not necessarily expecting that complex amount of refined selection to show up in CO6, but I've tried all sorts of combinations of creating and subtracting Local Adjustment brush strokes to refine the masking and sometimes it works, and sometimes... not so much.
I just like the Capture One tools for adjustments vs. Photoshop because they're "smarter". Except when the selection boundary is complicated like you say (and the blog images show).0
