I could never figure out why they call it a "vanity" mirror/light. "Insecurity" mirror is more like it.
Harsh lighting is my bane, as is any direct light. I still have some acne scarring (I'm working on it) and largish pores around the mouth, so direct light shows that up terribly. Diffuse light... I'm OK with.
Cameras. OMG. I'm a mutant in most photos. My face lengthens to 2', my nose looks like a clown's prop, my skin is dry as sand and yet the flash makes it look like an oil slick somehow... it's just AWFUL. I'll take photos, totally freak out at what I see, and run to decent mirror just to make sure I Do Not Look Like That.
Our bedroom mirror is the worst. Suspecting treachery, my wife and I actually conducted a scientific experiement on it a few weeks ago. And yup, it's confirmed: it adds 20-30 pounds in ALL the wrong places. Evil, nasty thing.
There's one small wall mirror in the hall outside the bathroom. Lighting is diffuse. Mirror is clear. And darn it, from most angles, I actually look basically *female* now in it. Honest to goodness. I LOVE that mirror.
If only society reflected me that accurately! Society seems to be more akin to cameras for me, lol...
