You know, that’s interesting that you brought that up, because I didn’t know anything about it till @virginiajenkins asked about grainy images in Exporting from Lightroom Question Then I found a video from adobe.com on using the Lightroom Noise Reduction panel, which showed what the ‘Color’ slider in the noise reduction panel does. I have never fooled with it, I guess most people leave it at the default setting of 25.
Just for fun, I found a night-time picture that I took while I was in Africa, and popped it into Lightroom. It was taken at ISO 6400, so I certainly had a lot of noise to work with!
Here’s a before and after Lightroom edit. (click to bring up images in the lightbox.)
Next, here are 3 crops showing different NR settings. The first one is all noise reduction off.
Next, only the color slider was changed, from 0 to 25.
Third, the NR settings are: Luminance 45 – Detail 75 – Color 25.
