Lightning Bolt

This is a script to generate animated lightning bolts, like the one below, with various options.

Lightning

Here is a quick summary of the options for this script:

Image X and Y size: Controls the dimensions of the final image. Recommended dimensions are a really tall image.
Number of frames: Number of frames (layers) in the final image.

Instability: large values make for quick fluctuations and jagged lightning, small values make for gentler curves

Old weathered paper effect

This GIMP script adds an old paper effect to the image. It is based off of the tutorial by RobA at http://forum.cartographersguild.com/showthread.php?533-Tutorial-Creating...

Seperate layers are added so the image can be fine tuned after the script is run.

Interpolation Plugin

This is an interpolation plug-in for the GIMP. It works by doing plane/curve fitting and calculating weighted averages. It takes samples from a grid of pixels from 'known' image areas, trying to fit a plane or a curve to each, and then uses those samples to estimate the 'unknown' image areas.

Upper-left: original image, upper-right: result after interpolation,
lower left: selection (a.k.a. output mask), lower right: input mask

FIL 1.7.2


FIL (Film Imitation Lab) is a powerful script for old photo simulation. FIL has a modular architecture and can use binary extension (plugins).

Current version: v1.7.2 (June 14th 2013).

Features:

Simple two colors border

This script produces a two colors border. You can choose the border width in % of the smallest image dimension, and the inner border width as a % of the whole border (and the colors, of course).
This can seem a bit complicated, but if you have pictures of different sizes and want a same-looking border, % will get you there.

Just remove .txt from the filename after downloading the script (don't know why it was added..)

Manual Lens filter (batch script)

This plug-in changes color balance to imitate images taken with Manual / Classic lenses but without any effect of degradation similar to images made with toy lenses.

See samples:

Version 0.1.2:
Introduces Linux support.

Copy the .scm file to:

Windows Vista/7 C:\Users\[USER]\.gimp-2.6\scripts

Manual Lens filter

This plug-in changes the color balance and brightens up the image to imitate images taken with Manual/Classic/Vintage lenses.

Below you will find two versions of the script one with Manual lens only (manual-lens_filter.scm) and one with Manual lens and Cool Manual lens (cool-manual-lens_filter.scm). Cool Manual lens uses the engine of http://www.registry.gimp.org/node/28306 to cool the image.

Adaptive saturation curve for LabCurves

Hi folks,

there is an update for LabCurves to have a curve for adaptive (or absolute) saturation adjustments. It is an external 16 bit program which can be semmlessly used from gimp with a python script.

Lab curves for GIMP

Basically it is not a plugin. It is a small standalone program in C++ and a wrapper script for seemless integration into GIMP.

It allows to alter an image with 16 bit L*a*b* curves with preview. You call it like a script from gimp. The image is send to that program, you play with the L*a*b* curves and when you save the altered image is send back and everything is cleaned up...
