I recently took some photos with all natural light. There was some noise in the photos so I used the luminance feature to get rid of it. The pictures look great in the develop tab but when I go back to the library to export them the noise comes back. If I save them onto a flashdrive or even just my desktop the noise is still there even though it disappears in the develop tab. Can't figure out how to get rid of it and keep it that way. I've already tried putting the luminance all the way to 100 to see if it will offset it but it doesn't. HELP PLEASE.
