I find removing noise in color lab mode is one of the easyest ways and does a good job. together with neat image that is 2 quick ways and does the job good, but i will definatly look into your way of doing it, when i get home.
i have just the right image to test it on.
Noisy image .Ofcause there the noise was added to make mood, but it could be fun to try and remove it agen

i will also test it on the normal noise i try to remove.
Thanks for the tip.
