What is »FFT Denoise« and how to use it?

Recommended Posts

Hi guys,


since I got Photo I wonder how to use the FFT Denoise filter the way it’s supposed to be used.

I never heard of it before and I can’t find a explanation for dummies or a tutorial for it.




Someone – please enlighten me! :D


Have a nice weekend

Short version: FFT means Fast Fourier Analysis. It means a transformation from the spatial domain (e.g. a matrix or an image) into the frequency domain. Different frequencies are separable there and selected ones can be lowered or eliminated ... such as image noise.

I was´t much into the help files either but as soon as I looked into them more seriously I find them pretty good!

I´d personally give them 8 out of 10 points :)


I just can´t search the html file in the browser and the german help file which I get from the MAS Version does not help me much cause I´m all english as far as Photography goes ;)
