SUMMARY

The discussion centers on the comparative accuracy of mirrors and cameras in representing images. It establishes that while mirrors flip images, cameras, particularly modern ones, utilize pentamirrors or pentaprisms to capture images, which can flatten the 3D perspective. Stereo cameras, equipped with dual lenses, provide the closest artificial representation of human vision. The conversation highlights that achieving a pseudo-3D effect in photography requires lenses with a shallow depth of field.

PREREQUISITES
  • Understanding of camera components, specifically pentamirrors and pentaprisms.
  • Knowledge of stereo cameras and their functionality.
  • Familiarity with the concept of depth of field in photography.
  • Basic principles of image representation and perception.
NEXT STEPS
  • Research the differences between pentamirrors and pentaprisms in camera design.
  • Learn about the functionality and applications of stereo cameras.
  • Study the principles of depth of field and its impact on photography.
  • Explore the latest advancements in mirrorless camera technology.
USEFUL FOR

Photographers, camera enthusiasts, and anyone interested in the technical aspects of image representation and perception in photography.

Which one is a more accurate representation of the image? (i.e. what we see with our own eye)

I've read that camera's actually flatten out the 3d image, but I have no clue what the consequence of this would be, while I do know that mirrors flip the image but I think that's the only thing that it does.
 
Science news on Phys.org
The closest we could get to actual human vision artificially is through stereo cameras which have two lenses and produce 3d images.

The two cases that you describe work in more-or-less the same way. "Modern cameras" also use a special kind of mirrors, called pentamirrors*. The "accurate" representation of an image depends on many parameters.

*High-end cameras use pentaprisms. Pentamirrors are used in order to decrease the cost. Mirrorless cameras have been recently introduced (~last year).

The only way to get a (peudo-)3d perspective in your photos is by using lenses with very shallow depth of field which allow you to isolate the focused object from its background.

I think what he meant by mirror is the normal plane mirror used in everyday life instead of the pentamirror used inside a camera.
