Removing photo noise

Jimmac has a nice blog post about problems of the noise in digital photography. It seems that my camera does not have such a big RGB noise problem as his test photos - it has some noise, but it does not have such a wide variance between the noise levels of different color channels. I had to look really hard to find a photo with noise high enough to be anoying (but I usually set it to ISO 100 manually, and my camera tends to over-expose slightly - the noise is usually in the lower-exposed areas). I will make tests at higher ISO values tomorrow.

Anyway, Jimmac points to the DCam Noise filter for Gimp, which looks really nice! And since I rarely do a batch editing of photos, the speed is not such a big issue for me.
