One of the things I’ve noticed about my camera is that when I get the exposure a little wrong and try to correct in RAW processing, I get a lot of color noise. This image for instance,
has a lot more to me magenta/pink/reddish noise than I would like in the sky and the ice, but I can’t figure out the most effective way to get rid of it. Anybody want to take a stab at it or share what they would do? When I try to select the color and then desaturate it, it looks all wonky, and adjustment layers are something that I’m still trying to figure out.

Noise ninja or neatimage? I think one or both of them have free trials and/or free low end version. One of them comes with Bibble and it’s pretty effective (can’t remember which one it is, but i’ve heard good things about both, so there’s that). A lot of the noise reduction stuff can be tailored to the color noise you’re getting.January 24, 2008 at 1:16 am #15005
I’ll check those out. The built-in reduction in Canon’s DPP and what I can find in PS CS2 are worthless, at least as far as I’ve been able to utilize them.January 24, 2008 at 1:18 am #15006sleepingParticipant
Here’s what NeatImage does with it (the default settings, no tweaking from me at all) I use it quite a bit for high-iso shotsJanuary 24, 2008 at 2:05 am #15007FlavivirusParticipant
Noise Ninja, original resolution (resizing downward would give the appearance of more detail, but any noise removal is hard on detail)
The other strategy I use is to place a noise-reduced image on top of an original, and gradient mask to the area that I see are the worst spots. This keeps detail where its needed, and noise is removed from where it isn’t.

dunno why it didn’t like that. i guess you have to copy and paste it? odd.January 24, 2008 at 2:19 am #15009

I think you need a .htaccess file in the fark directory. I can’t even go there directly.January 24, 2008 at 2:20 am #15010

Damn. That’s dramatic. I last tried NeatImage about five years ago and it was nowhere near that good. Thanks!January 24, 2008 at 2:58 am #15011sleepingParticipant

It doesn’t work so well for everything, especially if there’s a lot of fine detail you don’t want to lose, but I’ve found it pretty useful.
