Camera Test: Panasonic Lumix DMC-LX2

Noise Results at ISO 200

From the ISO 100 through 200 graphs you can see that the red channel has significantly higher noise levels while green has the lowest, a contributing factor to the excellent resolution rating of this camera at ISO 100 (most detail is found in the green channel). RGB curves respond in a similar fashion across the grayscale until the blue channel shows slightly higher noise in highlight areas and red channel noise drops. Therefore, if you want to apply any kind of noise reduction in post processing to images taken in this ISO range, target the Red channel especially in the mid-tones and shadows.
