I will be using three photos from this album.

1. Open a new file in Photoshop. I have made mine 500px by 300px.
   (CTRL+N)
2. Paste each image into the canvas, resize and arrange as you want them.
3. Next, select the eraser tool  and set the hardness to 0%.
4. For each layer, erase any parts you don’t want (in this case, the parts covering Ashley).
5. When you’re happy with the blending, you can save it or add extra effects (brushes, textures, colouring). I added PSD 006 to the image, to make it brighter.
6. Save as a .PNG or .JPEG file and you’re finished!
