Hello there,

I've done another video tutorial today.
This time, I show how to use the 'Fourier Transform' filter of the G'MIC plug-in for GIMP, in order to remove high-frequency noise in an old photograph.

Here is goal of this quick tutorial :

Another cool tutorial David; too bad this technique really only works with monochromatics (had issues with color in the past; maybe I was doing something wrong). :)

I'm loving these videos G'MIC tutorials!
Some minor differences between how I had been using, and how can be optionally (and better) used some filters.
Ty David!

I think it would have been better if I kept the original eyes, with perhaps a few minor changes, such as color and brightness. But laziness was greater.
Before / After.

Gnutux, I really like your tutorials, but they are very difficult to follow. I suggest that when you make a choice on the menu, leave the selection to stay awhile. Our look is different from the view of those who did the tutorial and already knows the choices on the menu.
Thanks.
