You can try and guess how i took this image in the living room, there is software masking or layering done to the image. I have been looking for this method for a week as i want to try something similar in the woods with a mirror and just today found out by experimenting how to do it.
I have to focus on my face without showing me in the mirror, and then take the image. Its not done with a phone or timer, so how did i do it.
