1) Colour Negative Inverter

Because of the more or less orange material of analogue colour films it is not very easy to invert digital copies of these films. Manual correction of the orange colour cast may be very difficult. This script performs an automatic colour correction and inversion.

Menu location of the script: <image>Filters/Photo/Colour Negative Inverter

2) Digital Graduated Filters


This script simulates graduated gray filters (GND) and graduated coloured filters. Two differently exposed images of the same subject can be combined to get a well exposed image with a soft gradient. Some options are included to control intensity and colour of the gradient.

3) Automatic Creation of Selections and Layer Masks - The Range Selection Script



The Range Selection Script is a tool for easy and automatic creation of selections and lay­er masks. The selections or masks include all parts of the image that are situated within a defined range of tonal values, colours, saturation or edges. Selections can be based on one of 16 channels. For detailed information and several samples have a look at the instructions.

4) Another Way of Rotation - The Straighten & Crop Script



The GIMP rotation tool is quite good. But I think straightening an image could be done even a little bit easier. I like the way it is done by my former image processing program more than working with the grid of the GIMP rotation tool. So I tried to imitate it by a script. Now you just have to place two mark points on a line that should be exactly horizontal or vertical after rotation and to run the script.
