I was thinking of which noise software to get, and was hoping I could get some feedback from the forums. which do you prefer, and why?? I have been thinking about Nik Define 2.0 because I use and love Silver Efex and and Viveza(Lightroom plugins). But I have also heard that Noise Ninja works well, although I don't know if you can use it with Lightroom? What other programs does anybody recommend? Thank you for your help in advance....Gregg
