This GIMP (GNU) tutorial demonstrates how to apply GIMP’s Cubism 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 Cubism. And from the subsequent Cubism dialogue box experiment with the settings, and then click OK.
The Cubism plugin modifies the image so that it appears to be constructed of small squares of semitransparent tissue paper.
I applied GIMP’s default settings. However, for personal results, experiment with the settings, and create a look you prefer.
Congratulations, your Painterly Cubism 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.
Your image will benefit from a Sharpening Filter: Filters then Enhance.
