I've edited some pics and used luminance to help reduce noise. After exporting, they still are noisy even though on lightroom they are not. I've read other people have the same problem. Anyone know what's happening?
What's happening is that you judging noise reduction in a view other than 1:1
Judging noise reduction and sharpening on a downscaled image (which Fit view is) is not representative.
Zoom to 1:1 and then compare your image in LR and exported one - I guess they will be identical.
