Photo Booth

“O wad some Pow’r the giftie gie us
To see oursels as others see us!” - To a louse … - Robert Burns
I have an asymmetric face. I would like to see the image that is being transmitted on FaceTime or recorded by Photo Booth rather than the “mirror image” that reassures us all by its familiarity (and inaccuracy). I know that I can flip images once they’ve been captured, but it would be grand to see them in real time. Am I missing a setting or does any one have a suggestion?
