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 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
One of the secrets of great image manipulation is to separate images into components. Frequency separation is often mentioned, breaking the image into so-called high-pass and low-pass layers. The high-pass layer separates out the sudden changes in an image and fiddling with this layer can enhance sharpening or even out blemishes. The low-pass layer can be used for smoothing out color transitions. Portrait photographers use this extensively for smoothing skin and removing spots. There is no native Frequency separation tool or filter built into gimp.
Hi this is my second Script-Fu and it seems a few people liked it so i thought i would post it here at the registry.
It's a SCM script so it will go in your scripts folder.
Just open a image and select the layer you want to work on and go to Filters>Artistic>Embroidery Stitcher.
The script is non interactive, that is to say it just runs with no adjustments (for now), and should work on any layer or image.I may add a stitch width adjustment later.
This script helps create simple rotating animations.
It asks for the desired number of animation frames (between 4 and 24 frames in increments of 4), and generates the corresponding number of layers each containing a rotated version of the image's background layer.
A choice of animation motion (circular and pendulum) is provided.
It has been tested in Gimp 2.6.11 on GNU/Linux and 2.8 on Windows XP.
Released v1.11 on 2012-07-02.
* Added pendulum motion
* fixed issue from lingering test code
