Building a Pinhole Camera

1. Overview

In this project, a simple pinhole camera has been designed and built. Three different pinhole sizes were tried to obtain the best quality.

2. Approach

As suggested in the project description, a box was used as a camera body. Inside of the box, one side was covered by a white screen while all the other sides were covered by black papers. On the opposite side of the white screen, the area for a pinhole and a camera aperture was made. The following is the final pinhole camera:

3. Results

The camera model being used is Olympus E-PL2 with exposure time of 60s. The pinhole size of 0.1mm seemed lack of lights. The pinhole size of 1mm was also a little bit dark but produced well-focussed images with reasonable quality. The pinhole size of 5mm gave the brightest, but focussing was not accurate.

More Images

Overall, the pinhole size of 1mm did the best job. However, as the sun set, it was hard to obtain the right amount of light and focus.
