Discussion Overview

The discussion centers around the differences in appearance when viewing oneself in a mirror versus in photographs. It explores the implications of dimensionality, image flipping, and perception, touching on both theoretical and conceptual aspects of visual representation.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that the difference in appearance is due to the 2D nature of photographs compared to the 3D perception in mirrors, with one participant noting that two eyes provide a more complete depth perception than a single camera lens.
  • Others point out that mirror reflections are flipped, which can alter the perception of one's features, as illustrated by the example of hand positioning.
  • One participant mentions that individuals with one eye, lacking depth perception, may experience similar discrepancies in appearance, indicating that depth perception is not the sole factor.
  • Another participant introduces the concept of parallax, suggesting that movement relative to the mirror or photograph can influence perception, and questions the common understanding of how mirrors flip images.
  • There is a discussion about the direction in which mirrors flip images, with some participants asserting it is front to back, while others challenge this notion by considering the effects of rotation.
  • One participant notes that since people are not perfectly symmetrical, the mirror image can differ from the actual appearance, further complicating the comparison with photographs.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the reasons for differences in appearance, with no consensus reached on the primary factors influencing perception.

Contextual Notes

Limitations include the assumption that depth perception is a critical factor, the dependence on individual symmetry, and the unresolved nature of how mirrors flip images.

An explanation given to the question, "Why do I look different in pictures versus a mirror?", cited that in a picture one views a 2D image but in a mirror one views a 3D image. This difference can effect the depth perceived in ones face.

Is this explanation valid?

My take is that the single camera lens only captures one image while ones live two eyes capture 2 images allowing for a 3D render.
 
Science news on Phys.org
Part of it is the fact that a mirror reflection is flipped compared to a picture. Hold up your right hand in a mirror and in a picture, in the mirror it looks as if your left hand is up.
 
If you ask a one-eyed person, who is incapable of depth perception, you'll find that s/he experiences the same thing.
 
That's because you can move the photograph or move relative to the mirror. Parallax is what gives it away.

If you were kept perfectly still and only allowed to look with one eye, you would not be able to tell a mirror from a similarly sized photograph.

By the way, just for fun, in which direction does the mirror flip images? A lot of people are confused about this one.

Front to back.
 
I liked to ask this in optics labs. You invariantly get a lot of people saying left-to-right. Then I ask them what happens if you rotate the mirror and what happens if you rotate the person looking into the mirror. That usually leaves them thinking for a while.
 
in the mirror you see your reflection, your mirror-image, since ppl aren't 100% same looking left and right, your reflection will look a bit different than the real you.
(her left is your right and vice versa)...
it's like identical twins, most are mirror images of each other, not the same looking...
that's a mirror

the photograph shows you as you, not mirror image
but yes, it does miss details, esp 3D vision, you're going from a 3D person to a 2D image,
that's not perfect either
