Step 1 - So what is it?
The name of this was trouble for me, so sorry if it's confusing at first. The tutorial is actually very easy to understand and can inspire you to do many things. This enables you to take a half of an image and turn it into a whole image. For example, I have a picture of a boy with half of his face on it. I flipped it horizontal and merged it with the other side after some touch-ups. Now it looks like a normal picture, if you ignore the eyebrows and hands.
Step 2 - Flip Horizontal
Start off by finding a picture or any time of image that you have half of. Click the link below to use the image I did from Stock Exchange:

Once you have it copied in your clipboard (right click > copy or CTRL+C) go create a new document. Before clicking OK, look at the width. Bring out the calculator and multiply the width by 2. This will give us room for both sides of the image. Now click OK, then paste the image inside the document. Then duplicate the layer. Now, finally go to Edit > Transform > Flip Horizontal.
Step 3 - Erasing away!
You should have two layers (both the same image). Move the second image to the right so it's identical to the left side. However, move it to the left a little bit more so it overlaps the edge. Now when we erase this part, it won't go to a transparent background. Now you should have some open space on the right side if you did this correct, that's OK.
Grab your eraser tool from the Toolbox on the left and change it to a brush on the top instead of pencil / block. Now change the size to anywhere around 100. I used 122. Also, make sure the hardness is at 0. Then gently erase the edges of the image on the right. Just make sure you don't see any grey/white boxes which represent transparency. If you do, then move the right side more to the left.
Step 4 - Finishing Touches
That's it! You should have one complete image now. If you don't fool around with the right side or move it to the left a little. Or choose a bigger brush and only use the ends of it to erase. This tutorial might seem simple to a few people, but I'm sure it might inspire you to do something larger then something like this or might expand your thinking cap!
Congratulations! You've completed the tutorial, however there is no PSD file for this since it came out to be one layer.
