Noise reduction is a matter of taste. I hardly do any noise reduction. If I do I reduce chroma noise.


Different cameras deliver different amounts of noise. With my 400D I shoot at ISO 1600 without noise reduction most of the time. In some cases I have to reduce chroma noise if the image was shot in dark surroundings and then I choose values between 3-6. Seldom more.


With the 50D I see much more chroma noise and at ISO 3200 and 6400 I sometimes have to set the chroma slider to the max. ( 20 ) Again, I do not touch the luminance slider. It smooths the image, and it looses details.


These are my personal preferences. Others may do things different.
