Dear experts, i found this video from David showing the descreening (with an older version). I want to use the Fourier transformation for an old photo, but i can not find the “invers” button which seems necessary for the procedure.
With Gimp and G’MIC 2.6.2_pre how can it be done?
Thanks a lot, Pithttps://www.youtube.com/watch?v=3137dDa6P4s
It changed to apply the filter a second time. Goes like this
Invoke the FFT filter, keep the one layer option until you get to know it. Ok to apply.
Paint out the defects, keep away from the ‘junk’ on the bottom half of the canvas and the bright spot in the centre.
You can open g’mic again and apply, but quicker is Filters → Repeat Last.
