This GIMP (GNU) tutorial demonstrates how to apply GIMP’s Predator Filter. To work along, you are welcome to download the Start Image I am working with Here. Unzip the file and open the image onto GIMP’s workspace.
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu choose View then select a Zoom Tool from the subsequent drop-down list.
Launch GIMP & Organise Its Workspace & Palettes
Open your choice of Start Image onto GIMP’s workspace - File then Open - Ctrl then O.
Ensure the Layers and the Undo History Palettes are visible, and then drag them into position over your workspace - (Windows then Dockable Dialogues - then click Layers and Undo History).
Now, from the top menu, choose Filters then choose Artistic and then choose Predator. And from the subsequent Predator dialogue box, experiment with the settings, and then click OK.
This filter adds a “Predator” effect to the image. The predator effect makes the image/selection look something like the view the predator has in movies (kind of a thermogram and that type of thing). This will reduce the image to edges in a few basic colours on a dark background. If there is an active selection, the filter effect will be applied to the selected region, otherwise to the alpha channel (the filter will add an alpha channel, if necessary). The filter works best on colourful RGB images.
I applied GIMP’s default settings. However, for personal results, experiment with the settings, and create a look you prefer.
Congratulations, your Predator Conversion is complete, and it is ready to save - top menu, then File then Save As. GIMP 2.8 - File then Export. Save Images Tutorial.
