Exceptional new plugin to restore faded transparencies/photos

Those of you following the ongoing discussions in our forums (connected to the official GIMP mailing lists) might have seen this already: There is an exceptional new plugin available to restore old/faded transparencies/photos!

Our user geoff has written an awesome new python plugin that makes it possible to enhance matt/faded transparencies or photos by reversing the aging process.

Some background: The plugin is based on an algorithm that recalculates the aging effect of color pigments based on physical considerations. It is possible for example to gain a nice new red color from a faded red color tone in a photo without having to do massive color/lighting corrections. It is a one-click-easy-and-simple-to-use plugin.

Installation instructions:
--------------------------
1. Find the script here: http://www.lionhouse.plus.com/photosoftware/gimp_plugins/ - download the restore.py file
2. copy it to the plugin directory of GIMP (Linux: /home/<user>/.gimp-2.6/plug-ins/)
3. make the script executable (in the plugins dir on a shell write "chmod a+x restore.py".
4. launch GIMP 2.6, and you should find a new main menu entry named "Restore".
5. open up a scan/photo and apply the plugin.

Here you'll find some Before/After images, as well as a really detailed pdf for the algorithm and a readme.txt:

Of course you can follow the original discussion in the forum!

Have fun with this amazing plugin!

PS: We've not tested this on the Windows platform yet.

    Thank you.
    It works fine under Windows too.

    The plugin seems to work with images from negatives too. But it seems to be aimed mainly on restoring transparencies.

    this is really cool! thanks a lot to the author of the plugin. i have a lot of kodak transparencies in my archive which are quite old. the plugin works very good and produces nice results.

    under windows you need to install pygtk, pycairo and pygobject in order to run the script with GIMP.

    Thanks for the encouraging comments. I have put out a new version of the plug-in with some bugs fixed. None of the bugs found affects restored images using the default settings. The main bug was that the "Degree of Restoration" slider did not always work as intended.

    I have been asked how to make the plug-in work in windows. I do not use gimp with windows and although the messages above confirm that it can be made to work it does not appear to be very simple. I wonder if someone could take the trouble to post some careful step-by-step instructions to help users interested in the plug-in.

    hello geoff!

    thanks for posting - our german community is posting more actively -> http://www.gimpusers.de/news/2009-02-28/aussergewoehnliches-plugin-fuer-alte-fotos.html

    they've been trying alot to get this working. here is a step by step-instruction for windows users:

    uninstall GIMP first.

    download:
    *ttp://www.python.org/download/releases/2.6.1/
    and install it. (don't use python 3)

    then download:
    *ttp://ftp.gnome.org/pub/GNOME/binaries/win32/pycairo/1.4/
    *ttp://ftp.gnome.org/pub/GNOME/binaries/win32/pygobject/2.14/
    *ttp://ftp.gnome.org/pub/GNOME/binaries/win32/pygtk/2.12/
    and install these packages.

    reinstall gimp - check "custom install" - then there will be a python-checkbox available. check it and install.

    IMPORTANT: you need python 2.6.1 - python 3 is not compatible as it seems... may people got it to work using this procedure!

    I would like to know how to install pygtk, pycairo and pygobject to run under windows. Where do I find this information?
    Thanks.
