I've never dealt with noise levels before, and it's not showing up much at all while post processing raw files. After seeing and reading your reply, I tried to lower the noise a few times and here was my latest at nearly 100% luminescence noise reduction.
I occasionally forget the noise too.
The more you manipulate the image, the more noise appears but since we're mostly working on an image "fit to screen", that noise is almost invisible. It's only when checking the 100% that it shows clearly.
Lowering noise can affect the image so you have to find the middle road.
