Effective noise reduction - How do you do it?

Seeing the strong reduction blurred the shot some, I wondered what would happen if I'd use a Gaussian Blur of 1.5px on the Blue channel and 0.5px on the Red. It's only some seconds work and almost has the same effect as me reducing noise each channel.

Evidently it would need work to sharpen up.

Pretty close, what were the manual steps you used?

Hmm if I remember well, I did noise reduction and sharpening in LR, then in PS used Gaussian blur on the separate channels: 1(1.5?)px on blue, 0.5px on red and 0.2px on green. Then back to LR for some more minor reduction (20 I think).

I never used blur to reduce noise but after seeing that plugin result, I noticed slight blurring when increased to the max so I wondered if they somehow applied it. When applied on the full RGB channel blur ruins the shot but the individual channels can handle quite some as long as you go soft on the green.

Some great responses and ideas, thanks again [MENTION=31330]J-see[/MENTION] & @wornish


I had a crack at some of the shots with people in last night, and the kids are easy - They were lit better, so I used lower ISO, plus their faces have much fewer lines & creases than the adults! :rolleyes:

I will have a look at Topaz, it looks like it does a good job!
