This GIMP (GNU) tutorial demonstrates how to blend two images using the Eraser Tool. To work along, you are welcome to download the Start Images I am working with HereUnzip the file and open the Start Images onto GIMP’s workspace.

Blend Two Images Using A Layer Mask Tutorial Here.

Notes
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.

Resize Images
Understand Layers
Understand Blend Modes
Launch GIMP & Organise Its Workspace & Palettes

Note
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).

Note
If you are utilising your own Start Images,
you must resize them so they are approximately the same size. In addition, it’s important to choose your Start Images with care: not all images are as easy to blend as my Longsands Start Images.

1/
To open the two Longsands Start Images onto GIMP’s workspace: from Gimps’ top menu choose File then Open - Ctrl then O. Now, from the Open Image dialogue box, navigate to the folder where your Start Images reside, then Ctrl-click to highlight both Longsands files - and then click Open.





2/
Now, from the Longsands 2’s Top Menu, choose Edit and then choose Copy.



3/
Then from the Longsands 1’s Top Menu, choose Edit and then choose Paste as and then choose New Layer - as illustrated below.



The Tynemouth 2 Image will now be Pasted onto the Tynemouth 1 Image - as illustrated below.





Note
It’s safe to Close the original Longsands 2 Image - top menu, then File then Close



4/
Now, from the left-side Toolbox, activate the Eraser Tool.



And to begin with, set the following Hard Round Brush settings into the Tool Options Box.

                        

Note
To produce a seamless blend, (throughout this tutorial) - you’ll need to change the Brush Size (Scale) and Opacity as needed.

Tip
You can quickly change the Brush’s Scale (Size) by tapping your Keyboard’s Square Bracket Keys.


 
Now, (still working on the Longsands 2 Image’s Layer); left-click and begin removing part of the Longsands 2 Image -as illustrated below.





Then reduce the Eraser Tool’s Opacity to around 48%.



And still working on the Top Layer, (Longsands 2): carefully remove (blend) the hardness between the Longsands 2 and Longsands 1 Images - as illustrated below.
 


Then further reduce the Eraser Tool’s Opacity, to around 20%, and continue to blend the two images together.



Undo Tip
If you find you have removed pixels in error, then return your image to a previous state by tapping Ctrl then Z.

Note
This blending technique quickly improves with practice.

Tip
Changing the Brush from Hard to Soft - Circle Fuzzy, (and further reducing the Opacity if necessary) helps to blend the two images together, seamlessly.



Tip
Final blending of the transition line between the two images requires very low Opacity
setting: - for full control, if necessary, apply the Brush one click at a time - until you have successfully faded the transition area.

After you have successfully blended your images, you are ready for the next step.



Zoom Tip
You will find removing stray pixels much easier if you enlarge your image by Zooming into it.



Tip
Now is a good time to save your Layered Image as a
GIMP XCF File.

5/
Now, from the left-side Toolbox, activate the Blur/Sharpen Tool.



And enter the following Blur settings into the Options Bar.



Then left-click and carefully blur away any stubborn hard areas.



Blend Modes Tip
If necessary, you can blend the Top Layer with the Bottom Layer using Layer Blend Modes - as fully demonstrated in my
Blend Modes Tutorial Here.





Tip
Now is a good time to save your Layered Image as a
GIMP XCF File.

6/
When you happy with your work: from the top menu, choose Image and then choose Flatten Image.
 


Face Image Tip
Open the Transparent Face Image onto GIMP’s workspace. Then Copy and Paste it onto your Flattened Image Blend. I demonstrate how to Copy and Paste Images at the beginning of this tutorial. And with the Move Tool, drag the Face Image to a suitable area. You can rescale the Face Image using GIMP’s Rescale Tool,
as fully demonstrated in my tutorial here.



7/
Congratulations, your Eraser Tool Blend is complete,
and it is ready to save - top menu, then File then Save As.
