how do i get accurate photos for measuring ratios

[fein123]

hi,
ive read some threads about focal length and all that. I dont have a selfie stick or anything and I figure the mirror has no distortion so i should use that, which i tried, but ive asked my friend and he says that my picture (iphone 14 zoomed in on face in mirror to max) fucks with my face, makes my lips looks really weirdly small (for example). So is that distortion idk. Whats the best way to accurately measure proportions like FWHR etc using a phone, not buying a fucking professional camera.

I tried selfie camera and back camera both from arms length idk was also a bit weird.
thanks

Selfies are the worst form of photos to take.

Mirror pictures/videos are usually very accurate (if you invert them), but the only issue is that you can never get a direct neutral angle shot, because obviously the phone would cover your face if you try take a neutral shot, so you always have to film below your jaw (which will make certain features look stretched/larger) or above your head (which will make jaw and shit narrower), so your proportions can get a bit distorted (though I would still say this is relatively accurate if you can get the positioning right).

Back-cameras are usually the most accurate and this is basically how you will look like in real life. Arms length away there should be very little distortion, though, if you are trying to measure ratios n shit then better to be secure and get a professional photo taken. Just go to a place that takes photos and get one taken. I would argue though there isn't much point in measuring ratios cuz good ratios and such are immediately noticable to every single human being. Good ratios dictate a good looking face, and every human has the ability to dictate whether a face is good looking or not by looking at it once cuz they subconsciously pick up all the ratios. I would say just look at ur back camera pic/video and see if you look good or not.
