Can't figure it out...

I've studied a number of posts about this FFT malarky now, but still can't get it to work!

I have a photo with fairly pronounced paper texture, and it sounds like FFT is the thing to use. I've already had a go at the picture with Neat Image, but I did loose a fair amount of detail in the process (and went a bit overboard with unsharp mask to compensate)

If FFT is going to give me a better result I want to give it a go!

I used an RGB image as instructed (though the image is B&W), but when I use the FFT filter in PS7 my R,G,B channels just go completely black!

What am I doing wrong??

I haven't attached a copy of the whole photo as the pattern is too distorted by compression. But I have attached the 'fixed' version, and a sample of the before and after.

ps. I tried the scan it twice at 180degrees thing too without any success. Maybe I'm just having a 'not too bright' day.

Hi Caitlin

I'm not sure what I did in the past but I had exactly the same thing happen to me. With your image in RGB mode, just run it through the filter. You should be fine. Perhaps with a little experimentation you can get better results than mine.
