Re: Science To The Rescue Again

You can try different way. Just put your lens cap on and shoot with different ISO values. This way you will shoot only the noise. Without messing with other light.
Then get pictures in RAW developer/PS and play with exposure and shadows.
Then you will see what exactly noise will look like and where it is. Like colors, pattern and so on.

Then you can consider how much of this you can tolerate .
