  • Fast Fourier

    I'm trying the FFT Tutorial and it's all good until I apply the IFFT. I get these crazy blotchy patterns. Can anyone help?

    It is difficult to tell without seeing the images. Try posting a copy of both the before and the after.

      nicksfan,

      make sure you follow the instructions EXACTLY. one missed or incorrect step in this and it will come out rather badly.

      also, i seem to recall that there may have been an image size limit to the FFT plugin. are you using FFT or FFT RGB?

      you might also try 'image analyzer'. it's a free program and it has a built in fft filter that's pretty easy to use.

        FFT greyed out
        by Liz
        Hi,
        Big fan of FFT and it happily does the right thing on my work computer. On my home laptop with CS3, FFT is greyed out under filters.

        I copied and pasted both FFT and IFFT into (through the Adobe Path) Filters. Shut down, restart, open Photoshop...it can see it but it's greyed...

        Help: FFT Filter
        by Liz
        Hi
        I've been using FFT for quite some time now. I sometimes have erratic results, but more so today. Despite re-installation of FFT, none of my problems were resolved. I'm using it on black and white wedding photos from the 70's, full of honeycomb. Lovely B&W's slightly discoloured through...

        FFT Madness
        by cheg
        Hi all

        I'm at my wits' end on this. I've searched this forum and pulled up all that had to do with FFT, I've installed the fft and ifft filters (in three different folder because I never see this filter appear anywhere!)

        I run Pshop 7.01 on a PC....where exactly do I find...

        FFT RGB Problem
        by Scrappy
        Hi there,
        My name is Jim from Japan.
        Recently, I found this filter.
        Then, after installing, put it on the scanned file, looks different.
        I'm using CS5. Is there any mistake?
        open a file, run FFT filter.
        It look below this.

        How can I fix this problem....
