What Do You See When Replacing a Screen with Your Eyes for a Real Image?

[pivoxa15]

I've used 35mm slide film (transparency) projectors and have always had to insert the slide upside down in order to get the image on the screen to come out right side up. I don't know whether this is also true of movie projectors. Some might have a more complicated optical system that inverts twice.

I take it that the picture registered on the film inside a camera is also up side down.

What happens if a picture is taken of an object that is inside the focal length of the lens of a camera? It would be a virtual image which would be troubling?

hasn't anybody here seen a ruler go near a large converging mirror? or anyone of the "magic" boxes?

if you use a large mirror you actually see another object coming out of the mirror. As an example, if you move meter stick towards the mirror, anouther meter stick will seem to emerge from the mirror to come out and touch the real meter stick. Its very cool to see.

You are talking about a virtual image?

It happens in every plane mirror that the closer you put the object to it the closer the virtual image is to the mirror on the other side creating the effect you are talking about. Is this what you mean?
