  • Applying FFT Filter - Problems with IFFT

    Trying to remove print texture from an old photo (image 1). Applying FFT and brushing out white stars in red channel (image 2) Applying IFFT to RGB yields black border around objects in print. What am I doing wrong?

    Thank for help!

    Difficult to tell as the images are too tiny, but it may be that you are working on a layer?

    You must make sure that there is only one layer and that the image is flattened and should be labelled automatically by PS as "Background". If not right click on layer and select flatten.

      Found problem. Yes, I was working on a background (flat) layer. For the Photoshop CC 64bit plugin to work, the file size needs to be below 130M.

        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 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...

        FFT Filter Grief
        by Liz
        Suddenly my FFT filter has stopped performing. See the attached image. I am in 8 bit, with flattened and duplicated file, which is approximately 6x4. So its not the size that's the issue. I click on the red channel, do the spot "thing" with a soft black blush. As I do so, I can see it...

        FFT filter
        by jmhinchey
        I used to be able to use the FFT filter on CS3. The last couple of times I tried it, it said "Microsoft had encountered a problem and needed to close".
        I deleted it from the computer and went back to the website and downloaded it again. Now it will run but when I go to the red channel...
