This GIMP (GNU) tutorial demonstrates how to paint onto a chalk board. To work along, you are welcome to download the Start Image I am utilising Here. Unzip the file and open it 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 choice of Start Image onto GIMP’s workspace - File then Open - Ctrl then O.
Tap your Keyboard’s D Key and then tap your Keyboard’s X Key. Your Foreground Colour should now be Solid White.
Chalk Colour Note
Set the Foreground Colour Swatch to a colour you would like your chalk to be.
Now, from the Toolbox, activate the Paintbrush Tool.
And (from the Options Box), activate the following Chalk 03 Brush.
Chalk Brush Note
There are three different Chalk Brushes, (as illustrated below). Therefore, experiment with all three, and discover a chalk application that suits your needs.
The Brush Size is entirely dependent upon your background’s Resolution, and the chalk appearance you are seeking. With this in mind, it’s important to experiment and find a Brush Size and Opacity that suits your needs.
Underneath the Dynamics tab, set the following Velocity Tapering Brush attribute.
Now, from the Layers Palette, create a New Transparent Layer above the Chalk Board Background.
Then, working on the New Transparent Layer, begin painting your name or a slogan over the chalk board - as demonstrated below.
Paintbrush Tool Note
You can alter the Brush’s application by experimenting with different mouse gestures. For example, a quick sweeping motion will produce a nicely tapered chalk application.
If you make a mistake, then press Ctrl then Z to go back a place.
Now, continue to paint your name/slogan onto the chalk board, experimenting with the Paintbrush settings to create a personalised look. After you have completed this, you are ready for the next step.
You can deepen the chalk effect by carefully painting over the same area until you are happy with the result.
Disable the Paintbrush Tool by clicking another Tool, perhaps the Move Tool.
Now, from the Layers Palette, right-click over the Chalk Writing Layer, and then from the subsequent drop-down list, select Duplicate Layer.
Layers Opacity Note
You can fade the chalk’s appearance by lowering the Layer Opacity.
Congratulations, after you have Flattened the Layers, (Image then Flatten Image), your work is complete, and it is ready to save.
To create extra impact, apply a Sharpening Filter of your choice - Filters then Enhance.
