Performs a value-inversion on the current layer, based on its representation in the YCC colorspace. The result is similar to the existing "Value Invert" command (but without that command's color-distortion introduced from low RGB values) and can be quite striking on certain source images.

This script simulates the cut-off of the first picture of a film roll of cheap cameras like Lomo. Role model was this picture from flickr. Copy it into the scripts folder from GIMP, you will find it then under Filters -> Generic -> Photo Border.
Unfortunately without FFTW3 so far (because I do not have it on my system yet), and thus slow.
The attachment is meant to be extracted into the GIMP program directory, if you want to place it elsewhere, just drop the executable to the right place. Translations for Italian, Japanese and Russian are included.
Creates a Lightsaber effect.
To successfully create the effect, you need a black layer with a white line (roughly 2-10 pixels wide)
The layer must be selected.

This script automates many of the steps in MarvinX's fantastic "Make a Planet" tutorial, with a couple of added features. There is an atmospheric haze around the planet, and there are stars on the background layer. This script does not do the IWarp step. I leave that to the individual user to make wherever they want.. Everything else is in here.
Lomo-Gimp tries to give your digital pictures the warmth of those taken by an old rangefinder analog camera. Think of it as a Kodak Instamatic or a Lomo Holga faking effect. It enhances contrast and saturation, and applies a light and a dark overlay, trying to emulate incorrectness in exposition. Please note this does nothing to emulate the chromatic aberration peculiar in pictures taken using a real Lomo.
