Cool Look filter

This is a bundle of two filters with similar action. The first one is cooling the white balance of the image while boosting red tones saturation, somewhat imitating Nikon look. The second one is cooling the dark tones while boosting red saturation on the brighter tones.

Balance colors through samples indicated as gray.

This little script was inspired by "GIMP tutorial - advanced color correction using sample point and curves" which nicely describes a method to get the color balance of a drawable right.
It expects an active path. If it's not there it exits unceremoniously.
The average RGB values of a 5 pixel radius area around the points in the path are taken and from these color adjustment curves are invoked with the aim to equalize them and thereby get the color balance right.

BIMP. Batch Image Manipulation Plugin.

BIMP is a graphical batch plugin to apply a set of GIMP manipulations on groups of images.
You can use predefined manipulations like resize, crop, flip, rotate, color correction, sharpen, watermark, format conversion, rename, but you can also select other installed plugins or script-fu and apply them to each image.

Windows version and source code for Linux/Mac systems:

Manual Lens filter

Batch Edit Color Balance, Brightness and Contrast

The script enables you to do two image adjustment operations to all images in a folder:

  1. Individually adjust the color balance in shadows, midtones and highlights
  2. Adjusting the Brightness and Contrast

You choose a folder with a folder browsing widget, you can also specify the file extension of the files you would want to change(useful if you have non supported files in the same folder).


This script converts the color temperature of an image. You can specify the color temperature of the original image, and the desired color temperature of the result, as well as a brightness correction factor. The script installs itself under the menu Filters/Colors/Convert Color Temperature.

The full documentation for the script is available at

The script works for Gimp 2.2, 2.4, and 2.6 .


This script converts the colors of an image, so that the foreground color (chosen, e.g., with the color picker tool) is either transformed to gray, or to the background color. The script can be used to remove color casts. The script installs itself under the menu Filters/Colors/White balance.
