Science Lab Experiment: Pinhole Camera
Demonstration Pinhole Camera
Object: To determine if light can be made to form an image by passing through a pinhole.
Materials: pinhole camera, photographic paper and developing chemicals
Diagram:
Method: A pinhole camera is constructed by placing a pinhole in
the end of a light proof container, such as a rolled oats
container, or crispy fries container. The cover is taken off
and photographic paper is inserted opposite the pinhole.
The container is placed outdoors on a sunny day and left
in a stable position for about 10 minutes.
At the end of that time the paper is removed (in the dark)
and developed and printed.
Observations: The print shows the scene in good focus, illustrating
that the light rays have passed into the box
to produce the image.
Conclusions: No lens can substitute for the clarity of a landscape
photographed through a pinhole.
