1. Yes, seeing yourself not-in-a-mirror is sometimes a bit jarring. (That also gets into all that "mirror image" option stuff in video conference tools like Hangouts.)
2. I'll go a step further from facial asymmetry and note that pictures of myself are often from different angles and body lengths than my blurry view in the bathroom mirror in the morning. That then calls to my attention various imperfections (mutterbaldspotmuttergutprofilemutter) that aren't visible in said mirror.
On the other hand, I do find pix of myself fascinating, not in some narcissistic way (sorry, Mrs. Snyder), but because they do show me a perspective that I don't normally have, (metaphorical) warts and all. That "getting out of my skull" point of view is fascinating (as well as educational).
Plus, I'm usually the guy holding the camera, so pix of me are much rarer than of the rest of the family crew.
Why do we hate seeing photos of ourselves?
There you are, clicking through your friend’s Facebook album, when suddenly you happen upon a picture of yourself — or rather, a slightly less attractive version of yourself. The “real” you appears to have been abducted, replaced with some second-rate knock off. What gives? you ask yourself. Is that really what I look like?
