Why the images of a pinhole camera are upside down?
An inverted image is formed in a pinhole camera because the light rays coming from the top and bottom of the object intersect at the pinhole, the top of the subject becomes the bottom, the bottom of the subject becomes the top during the projection. Thus, we get an upside-down image in a pinhole camera due to the linear propagation of light (light travels in a straight line) through the hole of the pinhole camera.
Not only the pinhole camera produces inverted or upside-down images, but all cameras produce inverted images. We can’t see it in any normal camera like DSL, SLR and phone cameras because it uses a mirror.
