Re: [Digital BW] Noise removal, RAW conversion

2006-04-22 by john dean

Well that's it. When you reduce color noise for instance in CS2's
noise reduction function, you reduce color sat everywhere. Sometimes
that is ok, sometimes it isn't. 

Taking a snapshot of the noise reduction, undoing that, and painting
in the noise reduction where it is need isn't difficult and gives you
a lot more control. Blending modes can do it but it is a global thing
then not a selective thing. 

It is the same principle of selective sharpening or selective gaussian
blurring when those are needed. I do all this kind of thing on a
background copy that I can click on and off to see the progress.
