This script adds several tools under Script-Fu - BgMask: "Extract background...", "Mask against background...", "Average linked layers...", and in BgMask 0.2 there are also "Extract background manually" and "Mask adjustments...". It can be used to mask moving objects/characters from animations with still background.
BgMask 0.3 introduces a new tool, "Blend Edges" which allows your masked objects to blend seamlessly into different backgrounds. Also, it improves the denoising algorithm of Mask Adjustments and adds a "Smoothen via paths" option.
This plug-in implements load and save of MagicLantern compatible YUV422 raw files.
MagicLantern is a free software add-on for Canon EOS cameras. This software
can take "silent pictures" as snapshot of the Camera Display
and saves them as uncompressed raw YUV422 files with extension .422.
The silent picture feature is useful to record timelapse sequences without moving the mirror
of the camera.
If you want to process such sequences of .422 images with GIMP (or GIMP-GAP) you should install
this file-raw-yuv422 plug-in.
This simple script add a new layer on top of the image filled with neutral grey and in overlay mode. You can use this layer with the dodge and burn tool to work on shadows and highlights without destroying datas.
This Python plug-in helps in the comparison of the left part of an image to the right part (equilibrium or not). It can be applied to any type of image and computes the centroid of the gray image pixels. The centroid is similar to the centre of mass concept, where mass is replace by another quantity; here it is the lightness and the greyness of the pixel.
This script creates predefined black and white variations and saves them as layers. Users can choose which variations should be created.
For more sophisticated possibilities use the channel mixer or other tools. This script just uses typical black and white variations, to provide a quick overview - just switch the layers visibility afterwards.
Install to .gimp-2.6/scripts in your homedir as bwvariations.scm, then start GIMP or click Script-Fu->Script refresh, you'll find it then under Script-Fu->Misc->bwvariations
