Hey guys, i've got a quick question if you don't mind. I understand that in order to view your full length in a mirror, that only a half-length mirror is needed; however, I'm wondering if this is true to just only see your face (if it was held up in front of you). So if my face is 15 inches, I would, theoretically need a mirror that is 7.5 to see my entire face, right? The reason why I'm asking is that I don't know how the reflections will interact with "what I see." Is it the top half of my face (above the eyes) that can be disregarded of the mirror? I'm not sure. Thanks in Advance!
