Question Restoring Photo just a question

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.

Regards

helen

Re: Restoring Photo just a question

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.

Re: Restoring Photo just a question

there are also moire pattern remover filters. i dont know of any that come with photoshop or paint shop pro, but there is at least one pay-for type out there.

i also just did a search on 'remove moire pattern' and came up with this tutorial on about.com: http://graphicssoft.about.com/cs/pho...emovemoire.htm . i dont know how good it is. i've never tried it, so, maybe you can tell us
