This GIMP (GNU) tutorial demonstrates how to create a neon light swirls pattern. To work along, you are welcome to download the Start Images I am working with Here. Unzip the file and open the Start Images 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.
Understand Blend Modes
Launch GIMP & Organise Its Workspace & Palettes
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).
To open the Four Swirl Start Images onto GIMP’s workspace; from Gimps’ top
menu, choose File then choose Open - Ctrl then O. Now, from the Open Image dialogue box, navigate to the folder where your Three Start Images reside, then
Ctrl-click to highlight all four files - and then click Open.
Copy And Paste Note
You are looking to Layer all four Swirl Images together using the Copy and Paste method. The best way to achieve this is to Copy and Paste the three smaller images onto the single (maximised) image - as demonstrated in this tutorial.
Now, from the Swirl 2 Image’s Top Menu, choose Edit and then choose Copy.
Then from the Swirl 1 Image’s Top Menu, choose Edit and then choose Paste as and then choose New Layer - as illustrated below.
You will now have a Two Layered Image - as demonstrated below.
Now, Copy and Paste the Swirl 3 Image onto the Swirl 1 Image, just as you did in the last Chapter.
Then Copy and Paste the Swirl 4 Image onto the Swirl 1 Image.
It’s safe to Close the original Swirl 2, 3 and 4 Images. (Top menu, then File then Close).
It’s a good idea to save your Four Layered Image as a GIMP XCF File.
You should now have a Four Layered image open on your workspace, (Swirl 1, Swirl 2, Swirl 3 and Swirl 4) - as illustrated below.
6/ Understand Layers - Understand Blend Modes
Now, (one at a time), change the Top Three Layers’ Blend Mode from Normal to Screen. (Screen render black pixels transparent).
Changing each Layers’ Mode to Screen displays all four Light Swirl Images - as illustrated below.
Activate the Top Layer. And from the top menu, choose Colours and then choose Hue-Saturation. Now, from the subsequent Hue-Saturation dialogue box, drag the Hue and Saturation sliders to positions that produces a colour and saturation you like the look of, and then click OK.
Then activate the Second, Third and the Background Layers (one at a time), and alter their Hue and Saturation.
Duplicate Layer (Deepen The Colours’ Intensity)
To deepen a swirls’ intensity: right-click over the each Swirl Layer, and choose Duplicate Layer from the subsequent drop-down list.
Rotate, Scale And Flip Note
If you prefer, (prior to flattening the Layers), you can Rotate, Scale and Flip each Swirl utilising the Rotate, Scale and Flip Tools. Resize Images Tutorial.
9/ Flatten Image
To finish, from the top menu, choose Image and then choose Flatten Image.
Congratulations, your Neon Light Swirls are complete, and your work is ready to save - top menu, then File then Save As.
