Some types of ambigrams read the same from different perspectives.
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.
That would be the Leonardo who hailed from Vinci, Italy. He could also write upside-down, right-to left, or left-to right, and did so on occasion.
As light travels through a convex lens (used in most slide projectors), the light and slide image are turned upside-down. Therefore, in order to appear correctly on screen, the image must enter the lens upside-down, which would then be inverted by the lens to appear right-side up. **** Furthermore, they are reversed left to right. What applies to the vertical holds true for the horizontal. The above holds true for any type of slide projector that performs similar to a Kodak carousel. However, the cube projector (Bell & Howell?) was different because the image bounced off of a mirror before going through the lens. I believe those slides were inserted into the cube right side up, but backwards (left to right), but I'm not sure.
"Henri Matisse's Le Bateau hung in New York's Museum of Modern Art for 47 days in 1961 before someone noticed it was upside down."-- Snopes Message Board, via googling "matisse upside down"
It's Wonderland, of course! Everything, as Alice had made up, was meant to be nonsense and everything that made sense would be twisted to be nonsense. Am I making any sense? (heheheXD)
Something that looks the same upside down has point symmetry.

The word is NOON.

Yes.
If it's both upside down and reversed from left to right, it would be equivalent to the image rotated 180 degrees.
Right. because if you are upside down you would flick your hands the other way so left= Right Right= Left
This is an ambigram.
