Now, from the foot of the Brushes Palette, click the following New Brush button.
And from the subsequent Brush Editor dialogue box, set the following Diamond settings. Then enter a unique name for your Sparkle Brush.
For personal Sparkle Brushes, it’s important to experiment with the Radius, Spikes, Hardness, Aspect Ratio and Angle settings.
Now that you have designed your Sparkle Brush, it will immediately appear in the Brushes Palette - as illustrated above-right.
If you cannot see your new Sparkle Brush, then click the Brush Palette’s Refresh button.

Set the Foreground Swatch to Solid White - or to a colour you would your Sparkle Brush to be.
(To set the Foreground to White, tap your Keyboard’s D Key then tap the X Key).
This type of Brush will always apply the Foreground Swatch’s Colour.
Now, from the left-side Toolbox, activate the Paintbrush Tool.
And enter the following Sparkle Brush settings into the Tool Options Box.
You can quickly Resize your Brush by tapping the Bracket Keys.
To apply your newly created Sparkle Brush, left-click over a shiny metallic area. To deepen the effect, left-click over the same area a further two or three times.
Reapplying the Brush will deepen its coverage.
Now, remembering to adjust the Brush Size wherever necessary, using the Bracket Keys: apply Sparkles (Catch Lights) over your image’s shiny reflective areas, such as the metallic helmet - as illustrated below.
Congratulations, your work is complete and your image is ready to save.
To permanently save your Sparkle Brush to GIMP’s Brushes Folder, apply your Brush onto a Transparent (Single) Layer. Then save it (top menu, then File then Save As) as a GIMP Brush gbr File, as Demonstrated Here.
Now you are familiar with this technique, you can have lots of fun applying catch lights to your favourite photographs.
