because you do.......
the brain processes the raw information,same reason you see pictures the right way up on a digital camera screen!
When the image reaches the eye, it is right-side up. The optics in your eye flip the image upside down in the process of absorbing the light. The up-side down image is then sent to your brain. You brain translates it back to right side up, and then creates the image for you to see. The image never appears upside down to you, because your brain does not create the image for you to see until it has flipped it back right-side up.
Just draw a couple of ray diagrams through a positive lens and you will see that a real image has to end up inverted, just like the image in your eye, which your brain then sorts out to a right-way-up image.
If you mean during printing and are referring to the projected image, it is upside down if you put the negative in the carrier the wrong way. The image should go upside down in the carrier so that it is projected right side up.
Your brain turns the image right side up because it is easier to try to have coordination right-side-up than upside down.
Inside the camera it's inverted but afterwards you take the negative or the print and turn it up the right way.
The stereoscopic microscope provides a right side up image
No, TV pictures are broadcast the 'right' way up - however, your eyes' lenses form an image on your retinas of everything in the world upside-down, and your brain adjusts the image to look correct.
yes they can see 65% of what they can see the right way up
The image is inverted when it reaches the retina. The brain then interperets the image as right-side-up.
Just draw a couple of ray diagrams through a positive lens and you will see that a real image has to end up inverted, just like the image in your eye, which your brain then sorts out to a right-way-up image.
Because the lense of a projector inverts the image, you put the slide in upside down to view it right side up.Iin the process of inverting the image, up becomes down and right becomes left..
