it works, but not as well. the amount of noise you get depends on how long the CCD is turned on, among other things. it would take care of hot and stuck pixels reasonably well.

Subject: Noise reduction


I am wondering if anyone has tried doing this as an out of camera operation? If it were possible, it would remove one of the problems with in camera noise reduction, which is the loss of camera functions while noise reduction is being calculated.
