Pinhole camera


A pinhole camera is a camera without a lens.  The name comes from the English word pin-hole, i.e. a hole as small as a pinhead. 

The pinhole camera allows to see a real image through a dark chamber.  Light from a scene passes through this single point and projects an inverted image on the opposite side of the box.

The aperture is a small hole of about 0.5 mm or less to produce a reasonably sharp image.
