Subject: How do I see myself as others see me?

Hello. This has nothing to do with vanity and is just a science question!! I 
have noticed that I look different in practically every video or photo I look 
at. It can practically be different people sometimes. I have been told that 
cameras etc..not only mirror the image but can fatten people too. Mirrors 
mirror an image as the name of them suggests so apparantley dont show the true 
you (at least as others see you). I have been told of a trick of putting two 
mirrors at a 90 degree angle to each other and to stare at the gap in between 
to see the true image as others see you from their perspective. Is this true 
and does it work? Are there any special cameras etc or photographic tricks 
that can do this? I realise it is impossible to see yourself objectively 
anyway but as stated before I am only interested in the purely 
technical/scientific aspect of this nothing else! thanks
