This is me in front of a mirror with the camera. You can see my reflection and various objects in the background.
This demonstrates that when light hits the mirror, it is reflected into my eye. You may see that in the background it looks like there is an 'infinity' of the lighting equipment that I used during the project.
This is because the light that is reflected into the first mirror, (the one in front of me) is reflected to the mirror behind me. When this happens, it reflects again and will go infinatley.
