I don't know why there isn't a _sticky_ DNR thread. Or a sticky thread on film restoration techniques and their application.
Digital Noise Reduction (DNR) is a key topic. It comes up ALL THE TIME on hundreds of threads. Many people don't understand it, or why it can be bad. People need to be educated on it.
It's even more imperative now that 4K/UHD discs are becoming a bigger thing, and over-application of DNR still rears it's ugly head regularly.
