Pinhole Camera

A pinhole camera is a simple camera, without lens, in the shape of a box. One of the sides has a small hole and it produces an inverted image of the outside world at other side.

The box should be painted black from outside and inside for better clarity.
The object whose image is to be seen should be in bright light.
Smaller the hole, sharper the image.
Temporary Black and White images are formed on the screen if a tracing paper is used. Permanent colored and b & w images can be obtained using photographic films instead of tracing paper.
In the below diagram, two boxes are placed one inside the other. The image of the outer object is created inverted on the inner box translucent screen.
