When looking through the toy photography images, this one stood out to be one of the most real-looking to me. One thing that makes it so realistic is the depth of field. The foreground is out of focus, while the mid ground is in focus, and the background is out. Also the vibrant colors bring the image to life. Lastly, the composition of the one fan standing with his arms up makes it seem as though there is actually a match happening.
This is actually real – it is called “toy” or “miniature” sometimes because the way itt is shot or manipulated post, makes the figures look like toys.
