Honeycomb patterns in paper
« on: October 29, 2006, 06:56:54 AM »
I was browsing the 'difficult' photos and noticed one probably from the 70s which had a very marked honeycomb texture in the paper.  Difficult at the best of times since any cloning or pixel shifting then disturbs the underlying pattern.

I came across a plugin and technique called 'FFT (Fast Fourier Transform)' and it actually works quite well.  If anyone is interested, there's a tutorial together with a link for the download of the plugin on Retouchpro - "Using the FFT filter to remove photographic paper texture" under their tutorial section.  I'm not sure whether one has to be a member or not to look through those.  No biggie, it's a great place to be anyway :)

Just thought it worth mentioning as one of those little heard of plugins.

I understand the fft filter is pretty good. But it doesn't work on macs.   :(

Hi John

That issue was raised on the forum and here is the reply -

There IS a mac version. Itís called ImageJ

Image J is part of The Image Processing Toolkit
Available Here for Free
http://rsb.info.nih.gov/ij/download.html
ImageJ runs on Linux, Mac OS 9, Mac OS X and Windows
The Docs are here
http://rsb.info.nih.gov/ij/docs/
And the bit about FFT is here
http://rsb.info.nih.gov/ij/docs/menus/process.html#fft

It is Not a plugin but a complete program. You will need Java Installed.

I don't know whether that helps at all.  This was a thread from a year ago, so I'm unsure of recent developments.  I'm not a regular Mac user.

Worth a try maybe?
