Zoom videos are mirrored by default, because it looks more natural to see yourself reflected back at you in that way. Other participants still see the non-mirrored, normal you. You can turn this mirroring feature off, but it's disorienting and takes some getting used to. Still, it’s useful to turn off mirroring if you find yourself wanting to share a physical object by holding it up to the camera, like a page of notes or some flash cards. Or maybe you just have a sick face tattoo and you don’t want it to read “STERGER ON.”
Go to your video settings and uncheck "Mirror my video." That’ll let you see your true self.
