Please explain this girls tattoos. She obviously didn’t get tattered that way.
I noticed this on videos of police cars too. Where the letters appear to be going backwards in the wrong way. But the letters orientation to the door don’t make sense to me. Just like this lady’s tattoo.
(Whatever she’s talking about his relevant to this thread. I’m just using her as an example)
As I understand it, some people post videos in reverse orientation to defeat some kind of security algorithm. Others probably know more about it than I do.
Sometimes people just flip videos before reposting them to avoid automated copyright filters and such
Ninjaed!
I get that part. TikTok’s default is reverse image but how does the letter go from being by the shoulder to starting out in the middle?
What do you mean? Which letter?
If you reverse the image, it just looks like a normal tattoo:
I have no idea what “dead ____ don” means, though. It’s probably not an homage to “Don’t Dead Open Inside” 
Ok I get it now. Lol
I guess I just have to see it. I’m not able to picture in my head on my own.
Maybe it’s a completely other tattoo. A curly q or something.
Yeah, it’s surprisingly difficult to flip things in our heads like that. Mirror images are a part of many IQ tests, e.g. Mirror Image Test — Spatial Reasoning Training | Cognitive Train
It says Dead Girls Don’t Cry.
Makes sense 
I wish I had x-ray vision too.
I just looked through her other videos.
It’s crazy how she lives her entire life in reverse.
I think that’s for stuff that might get taken down for copyright - the idea being that the automated systems won’t recognize a scene from a film if its flipped. I don’t think this actually works anymore, if it ever did.
In this case, though, it’s just that a lot of phones these days automatically flip the image when you’re taking a selfie, so that it functions more like a mirror - apparently, a lot of folks instinctively expect their camera to act like a mirror and get thrown when it doesn’t.
I think of lot of them just post the file generated by the selfie-camera, which is a mirror image; as opposed to the outward facing camera which produces right-reading imagery. This begs the question whether they care that text is reversed, or even KNOW that text is reversed…
Yep, my phone does this.
If you use the forward-facing camera, the image is normal. If you use the camera that faces the user (aka selfie mode), the image is flipped like a mirror.
I believe most phones work this way.
Well, the selfie camera isn’t any more of a mirror than the rear camera. There’s no optical flipping going on. It’s a setting that some camera apps or phones will do in software, but it’s because of user expectations (like Miller said), not because the front camera is optically reversed. You look the same orientation to either lens, but special software flips it to the “wrong” way so you look like you do in a mirror.
The settings on Samsung Android cameras include whether to mirror-image the selfie cam or not.
But the description for that switch describes it backwards because of the public’s assumption that mirror imaged is normal and so "flipped " is mirrored-mirrored.
I understand why the phone would display the mirrored image to the user while they’re recording the video, but why is it stored that way?
So WYSIWYG?
Yeah, exactly that.
I don’t have a cite handy (edit: ChatGPT found The Mirror Effect on Social Media Self-perceived Beauty and Its Implications for Cosmetic Surgery), but I remember reading somewhere that users prefer seeing their own faces as mirrored (that being the primary exposure we get of our own faces), even when they can’t reliably tell which version is the mirrored one.
I guess if you’re sharing a selfie instead of a group photo, you’d want to share it just the way you see it. Reversing it back the “correct” way makes it look a bit different to your own eyes.
On a technical level, though, it depends on the implementation. Different camera apps and phones and OSes will handle it differently. Some will let the user see it one way while saving it another way.
And different implementations also store it differently. For an image, sometimes the raw bitmap (well, compressed blocks) are actually flipped in the bytes, while other times it’s just a JPEG EXIF orientation bit that you can set — and that makes it trivially and losslessly rotatable/flippable, no matter the actual pixels on disk. The orientation is encoded in the metadata and the image viewer parses that before rendering (or not, which is sometimes why cross-OS photo sharing doesn’t show the right orientation).
For a video it’s more complicated and depends on the specific codec (and container format). I don’t know the deets offhand.
