Hey, thanks! The enlargements make it much easier to see what we're talking 
about. I think you're right. There's something in the processing that's messing 
with things. Not sure exactly what.

Mayhap I"ve been resorting to plug-ins too frequently and not hand-wrangling 
enough. Or maybe I'm just not paying close enough attention at each step of the 
processing.

At any rate, the New Harbor shot is basically a throw-away, as an early effort 
with the 10-stop ND, and not under the best conditions for that effect. 

The other halos we talking about, around the lighthouse in the over-the-top Sfx 
image, I have corrected and eliminated by doing what I mention above, playing 
attention at every step of the post-processing. Haven't posted the new version 
yet, and may not. Depends on how the eventual print looks. If I like the print, 
I'll repost the shot. If I don't, into the electronic bucket it goes. <g>

Thanks again. That granular level example did the trick.
