The following images illustrate the pin-hole camera we built. The three inside sides of the box have been covered by black paper and one side with white paper. In addition, we taped black tape around the box to prevent light leaking.
In this project, we design a pin-hole camera with a cardboard box and a digital camera. During the experiment, we found the most difficulty part is the design of the pin.
The following images illustrate the pin-hole camera we built. The three inside sides of the box have been covered by black paper and one side with white paper. In addition, we taped black tape around the box to prevent light leaking.
We designed three sizes of pins. The following image illustrates, the small pin (0.1mm), the medium pin (1mm) and the large pin (5mm), from left to right, respectively.
The first scene we took is the outside of Smith Hall from the door of NSH. The following images illustrate the images captured by the small, medium, large pins, from top to bottom, respectively. We set 1 min as the exposure time for the small pin and 40 secs for the other pins. Observe that the top image is not very clear because the pin is so small and there was no enough light in last Sunday. The second image is a little sharper than the last image due to the smaller pin size. But the last image is much bright than others.
In this example, we took three pictures of the Cathedral of Learning from the 6th floor of Gates Building. We found all the images are quite blur. It is because the building is very far away.
In the following, we show four images taken by the large pin (5mm) and 40 secs for the exposure.
