This is Manny Librodo's Sharpening moves. You can give it a try and you will be surpised with the quality. One caveat, there really is no one set formula for sharpening so you may want to experiment with different amounts for different images.

Questo script in python altro non è che una mia personalizzazione e relativa traduzione in italiano basato sul codice "Batch resize" di Carol Spears.
Ho volutamente messo i margini a zero perchè le miniature impaginate possano essere agevolmente tagliate ed ottenere delle piccole foto da un'impaginato grande. Io lo uso per creare in maniera del tutto automatica dei mini album partendo dall'impaginato grande, infatti ci sono pure le misure che uso io col mio laboratorio che stampa in banda 406mm. Si può comunque utilizzare pure per creare delle provinature nei vari formati.  read more »

This plugin losslessly decomposes a layer of an image into layers of wavelet scales. This means that you can edit the image on different detail scales (frequencies). The trivial recomposition of the image can be done by GIMP's layer modes so you can see the results of your modifications instantly. Among the applications are retouching, noise reduction, and enhancing global contrast.  read more »

This script automates a Photoshop tutorial on how to make "something that looks like a plasmid under an electron microscope." GIMP doesn't have the Chrome filter that Photoshop does, so this script uses a combination of gaussian blur, colorizing, and embossing to achieve a similar effect. It's not quite perfect, but it's close.
The attached jpg is something similar to what the resulting run will look like using the default parameters.
Enjoy!
