An instrument that fixes light into an image. Also the chosen viewpoint a scene is seen from.
Latin camera (a vaulted room), from Greek kamara; through camera obscura ('dark chamber,' the pinhole box that projects an image) the word narrowed from a whole room to the instrument, and then to the viewpoint a shot is taken from.
An instrument that fixes light into a lasting image, and, by extension, the chosen point a scene is seen from.
