No Noise

Just got my first m9.  I'm using Capture One Pro 10.  I took a series of photos in daylight stopped down at every iso, and I do not see any color noise in any of them, even in the 2500 iso shot.  I'm viewing the raw files in Capture One and I didn't set any import preset.  Does Capture One automatically get rid of color noise?

You won't really. Noise creeps in when one takes low-light images, often with extremely underexposed shadows. Well-exposed daylight shots of limited contrast will rarely show noise, just a certain grittyness at high ISO.

Most raw developers do have a preset for colour noise related to ISO. C1 may have as well.

Yes- but under what circumstances? I have plenty of M8 shots @ ISO 1600 that are perfectly clean - but exposed generously in good light. The M8 needs careful technique to handle high ISO. The M9 is a bit more forgiving. 

You want to see noise? Underexpose in low light.

Enlarge to 100%, MacBeth color card is nice subject.  You will see noise. Reduce it.    Make one for each ISO .

 

Better if you can isolate blue, red and green like you can with photoshop,  then isolate channel by channel.  Save as an action with photoshop.

 

This is a tremendous help if you push ISO in post as you are starting with a cleaner image so noise does not get pushed..
