The Latin words camera obscura can be roughly translated as darkened room
or chamber. A camera obscura is created when a small hole or aperture is made
in a darkened space, producing an inverted image of the scene outside onto an opposite surface within.
This phenomenon has helped to prove that light travels in straight lines. A lens is used to increase the brightness and sharpness of the image. Camera obscura have been used as an aid to drawing and, particularly during the Victorian era, a popular form of entertainment.

The following video below shows how to create a camera obscura in a room yourself. The video show how the projected image changes within the room as it adapts to the changes outside. This also proves that it is possible to film this movement and may actually look more accurate than just filming the view from directly outside with a camera.
