Restoring Photo just a question

[sergio2263]

Hi Guys,

When restoring photo with moire pattern, do you run the FFT filter before anything is done to the photo, or would you guys adjust levels etc. At the moment I am running the FFT filter to a moire photo before I do any work.

Many thanks in advance.

... and you are doing the right thing ...

FFT typically is not effective on a true Moire pattern which is different from the repetitive pattern you mighyt find on the textured photopaper uses in the 70's and 80's.
In any event, you would usually eliminate the moire first thing in your work flow. Level adjustments, sharpening, etc only tend to amplify the pattern making it more difficult to eliminate later in your workflow.

Hi Murray,

Thanks very much for your reply, much appreciated. I have tried to adjust level and found the photo to be worst off when running through FFT filter afterward.
