talking about forests and trees..

dark frames can only ever reduce the pattern noise in an image. all the random noise cannot be helped.. the reason you need a lot of dark frames is to subtract the noise that has some pattern/repeatability to it without making the random noise significantly worse. hope that makes sense..
