Whatbis a 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.
