This GIMP (GNU) tutorial demonstrates how to create vivid painterly forest stripes. 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.
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).
Launch GIMP & Organise Its Workspace & Palettes
Open your Start Image onto GIMP’s workspace - Ctrl then O.
2/ Increase Saturation
Now, from the top menu, choose Colours and then choose Hue-Saturation. And from the subsequent Hue-Saturation dialogue box, increase just the Saturation to around 55, and then click OK.
3/ Add A Motion Blur
Now, from the top menu, choose Filters then choose Blur and then choose Motion Blur. From the subsequent Motion Blur dialogue box, enter the following Linear Blur settings, and then click OK - as demonstrated below.
For personal results; it’s important to experiment with different Motion Blur settings.
To create extra impact, apply a Sharpening Filter of your choice - Filters then Enhance.
Congratulations, your forest stripes conversion is complete, and it is ready to save.
