This GIMP (GNU) tutorial demonstrates how to create a Strawberry Sunrise photo conversion, and how to apply Sun Rays to an image. 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.
Before you begin, you may want to Google the words Sun Rays. Looking at actual sun rays before creating yours, will provide a good starting point.
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.
The Free Select Tool
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 Colours and then choose Colourise. And from the subsequent Colourise dialogue box, set the following Saturation and Lightness settings, or experiment, and then click OK.
To create personalised hues, experiment with the Saturation and Lightness settings.
It’s time to create your sun rays. Therefore, from the Layers Palette, click the following to Create a new layer tab. And from the subsequent New Layer dialogue box, name the Layer something like Sun Rays. Then mark Transparency, as illustrated below-right, and click OK.
A New Transparent Layer will be applied above your image, as illustrated below. You’ll be creating your Sun Rays on this New Transparent Layer.
From the Toolbox, activate the Free Select Tool. (Tutorial for Beginners Here).
And enter the following Add to the current selection and 20 Feather edges settings into the Tool Options box.
The Feather setting is dependant on your image’s resolution and the Sun Rays you are seeking to achieve.
Now, (working on the Sun Rays Layer), left-click and draw multiple rectangular shaped sun rays, as illustrated below.

Disable the Free Select Tool by activating another Toolbox Tool. I always activate the Move Tool.
Now, ensure the Foreground Colour is set to Solid White.
Then from the Toolbox, activate the Bucket Fill Tool.
And enter the following settings into the Tool Options box.
Now, left-click over your sun ray selections, to fill them with Solid White - as illustrated below.
If you like, you can fade the Sun Rays by lowering the Sun Rays Layer Opacity.
From the top menu, choose Select then choose None.
Prior to Flattening your image, you may want to save it as an XCF File.
When you are happy with your Sun Rays - from the top menu, choose Image and then choose Flatten Image.
To create extra impact, apply a Sharpening Filter of your choice - Filters then Enhance.
Congratulations, your Strawberry Sunrise Conversion is complete, and it is ready to save - top menu, then File then Save As.
Now you are more familiar with this technique, you can have lots of fun applying Sun Rays to your favourite images.
